description: This paper proposes an algorithm to minimize weighted service latency for different classes of tenants (or service classes) in a data center network where erasure-coded files are stored on distributed disks/racks and access requests are scattered across the network. Due to limited bandwidth available at both top-of-the-rack and aggregation switches and tenants in different service classes need differentiated services, network bandwidth must be apportioned among different intra- and inter-rack data flows for different service classes in line with their traffic statistics. We formulate this problem as weighted queuing and employ a class of probabilistic request scheduling policies to derive a closed-form upper-bound of service latency for erasure-coded storage with arbitrary file access patterns and service time distributions. The result enables us to propose a joint weighted latency (over different service classes) optimization over three entangled "control knobs": the bandwidth allocation at top-of-the-rack and aggregation switches for different service classes, dynamic scheduling of file requests, and the placement of encoded file chunks (i.e., data locality). The joint optimization is shown to be a mixed-integer problem. We develop an iterative algorithm which decouples and solves the joint optimization as 3 sub-problems, which are either convex or solvable via bipartite matching in polynomial time. The proposed algorithm is prototyped in an open-source, distributed file system, {\em Tahoe}, and evaluated on a cloud testbed with 16 separate physical hosts in an Openstack cluster using 48-port Cisco Catalyst switches. Experiments validate our theoretical latency analysis and show significant latency reduction for diverse file access patterns. The results provide valuable insights on designing low-latency data center networks with erasure coded storage.

Sexual morph: Ascostromata solitary to gregarious, or in groups, superficial, shield-like, dark brown to black, carbonaceous, flattened, connected to internal stroma by hyphal tubes or clusters, ascomata margin smooth, Internal stroma easily distinguished, well-developed, with ridges radiating from the centre to the outer rim, ridges containing elongate locules, which open by a longitudinal slit and contain numerous asci, cells of ascostromata thick-walled, elongate and composed of black, amorphous tissues in the stromatic crust. Hamathecium of dark brown to hyaline, septate pseudoparaphyses, swollen and brown at their apices. Asci 8-spored, thick-walled, bitunicate, cylindrical, short-pedicellate, with a distinct ocular chamber. Ascospores 2–3-seriate, ellipsoidal, with rounded ends, hyaline to dark brown, 1-septate, constricted at the septum, smooth walled (Hyde et al. 2013).
 Notes:— Sections of fruit-bodies of the type specimens of Cocconia palmae F. Stevens (Stevens 1927), current name Dianesea palmae revealed two different taxa and Imicio & Cannon (2002) stated it was clear that the original description was a composite of both species. Hence, in this study we re-examined the morphology of both Cocconia placenta under Cocconia and Cocconia palmae under Dianesea. We have provided only a single description as this genus contains a single species with two varieties.

description: The propagation of surface plasmon polaritons in thin films of topological insulators is studied. The materials considered are second generation three dimensional topological insulators Bi$_2$Se$_3$, Bi$_2$Te$_3$, and Sb$_2$Te$_3$. Dispersion relations and propagation lengths are estimated numerically, taking into account the variation of bulk dielectric functions of topological insulators as well as substrate using the Drude-Lorentz model. Key factors affecting propagation length are identified and ways to modify the dispersion relations are suggested. The explanation of the apparent discrepancy between the experimental data for Bi$_2$Se$_3$ and theory is proposed.

description: The intrinsic nuclear shapes deviating from a sphere not only manifest themselves in nuclear collective states but also play important roles in determining nuclear potential energy surfaces (PES's) and fission barriers. In order to describe microscopically and self-consistently nuclear shapes and PES's with as many shape degrees of freedom as possible included, we developed multidimensionally-constrained covariant density functional theories (MDC-CDFTs). In MDC-CDFTs, the axial symmetry and the reflection symmetry are both broken and all deformations characterized by $β_{λμ}$ with even $μ$ are considered. We have used the MDC-CDFTs to study PES's and fission barriers of actinides, the non-axial octupole $Y_{32}$ correlations in $N = 150$ isotones and shapes of hypernuclei. In this Review we will give briefly the formalism of MDC-CDFTs and present the applications to normal nuclei.

description: The magnetic properties of the layered oxypnictide LaMnAsO have been revisited using neutron scattering and magnetization measurements. The present measurements identify the Néel temperature $T_N$ = 360(1) K. Below $T_N$ the critical exponent describing the magnetic order parameter is $β$ = 0.33$-$0.35, consistent with a three dimensional Heisenberg model. Above this temperature, diffuse magnetic scattering indicative of short-range magnetic order is observed, and this scattering persists up to $T_{SRO}$ = 650(10) K. The magnetic susceptibility shows a weak anomaly at $T_{SRO}$ and no anomaly at $T_N$. Analysis of the diffuse scattering data using a reverse Monte Carlo algorithm indicates that above $T_N$ nearly two- dimensional, short-range magnetic order is present with a correlation length of 9.3(3) Å within the Mn layers at 400 K. The inelastic scattering data reveal a spin-gap of 3.5 meV in the long-range ordered state, and strong, low-energy (quasi-elastic) magnetic excitations emerging in the short-range ordered state. Comparison with other related compounds correlates the distortion of the Mn coordination tetrahedra to the sign of the magnetic exchange along the layer-stacking direction, and suggests that short-range order above $T_N$ is a common feature in the magnetic behavior of layered Mn-based pnictides and oxypnictides.

description: In a previous article we suggested a method to overcome the diffraction limit behind a telescope. We refer to theory and recent numerical simulations, and test whether it is indeed possible to use photon amplification to enhance the angular resolution of a telescope or a microscope beyond the diffraction limit. An essential addition is the proposal to select events with above-average ratio of stimulated to spontaneous photons. We find that the diffraction limit of a telescope is surpassed by a factor ten for an amplifier gain of 200, if the analysis is restricted to a tenth of the incoming astronomical photons. A gain of 70 is sufficient with a hundredth of the photons.

description: Using ab initio calculations, unexpected structural instability was recently found in the ground state of the U$_2$Mo compound. Instead of the unstable $I4/mmm$ structure, in this work the $P6/mmm$ ($\# 191$) space group, usually called $Ω$-phase, is proposed as the fundamental state. Electronic and elastic properties are studied in this work in order to characterize the physical properties of the new ground state. The stability of the $Ω$-phase is studied by means of its elastic constants calculation and phonon dispersion spectrum. Analysis of isotropic indices shows that the new phase is a ductile material with a minimal degree of anisotropy, suggesting that U$_2$Mo in the $P6/mmm$ structure is an elastic isotropic material. Analysis of charge density, density of electronic states (DOS) and the character of the bands revealed a high level of hybridization between $d$-molybdenum electronic states and $d$- and $f$-uranium ones.

description: Research on Life Cycle Assessment (LCA) is being conducted in various sectors, from analyzing building materials and components to comprehensive evaluations of entire structures. However, reviews of the existing literature have been unable to provide a comprehensive overview of research in this field, leaving scholars without a definitive guideline for future investigations. This paper aims to fill this gap, mapping more than twenty years of research. Using an innovative methodology that combines social network analysis and text mining, the paper examined 8024 scientific abstracts. The authors identified seven key thematic groups, building and sustainability clusters (BSCs). To assess their significance in the broader discourse on building and sustainability, the semantic brand score (SBS) indicator was applied. Additionally, building and sustainability trends were tracked, focusing on the LCA concept. The major research topics mainly relate to building materials and energy efficiency. In addition to presenting an innovative approach to reviewing extensive literature domains, the article also provides insights into emerging and underdeveloped themes, outlining crucial future research directions.

description: Spontaneous symmetry breaking is an important concept for understanding physics ranging from the elementary particles to states of matter. For example, the superconducting state breaks global gauge symmetry, and unconventional superconductors can break additional symmetries. In particular, spin rotational symmetry is expected to be broken in spin-triplet superconductors. However, experimental evidence for such symmetry breaking has not been conclusively obtained so far in any candidate compounds. Here, by 77Se nuclear magnetic resonance measurements, we show that spin rotation symmetry is spontaneously broken in the hexagonal plane of the electron-doped topological insulator Cu0.3Bi2Se3 below the superconducting transition temperature Tc=3.4 K. Our results not only establish spin-triplet superconductivity in this compound, but may also serve to lay a foundation for the research of topological superconductivity.

Active Learning for User-Tailored Refined Music Mood Detection
Creators: name: Sarasúa, Álvaro
Publisher: name: Zenodo
Year: 2011

description: Mood detection is an increasingly area of interest in Music Information Retrieval (MIR). This thesis, which is built on top of the work by Cyril Laurier and Perfecto Herrera in the Music Technology Group (MTG), deals with two identified problems which are interrelated: first, the need for expanding current mood tags (happy, sad, aggressive and relaxed) to more specific and complex emotions; second, the need for customization that these complex emotions require. For the first problem, four new mood classifiers are implemented: mysterious, humorous, sentimental and triumphant. New song collections are created and user-validated in order to achieve this task. For the second issue (customization), the use of active learning techniques is explored. Active learning is based on the idea that a system can converge to its best performance more quickly by being able to smartly select those songs with which it is trained. A state-of-the-art review on active learning techniques is presented and uncertainty-based techniques are tested over the new and already existing song collections. ANalysis Of VAriance (ANOVA) showed that there is no significant improvement between active learning and standard full-set batch training. Active learning, though, would require the processing of fewer instances to achieve equivalent performance. As an extra experiment, a new happy collection with classical music is created. Different cases are studied and compared: a system trained with the old collection (that does not contain classical music) tested over the new one and vice versa, a system trained joining both collections and tested by 10-fold cross validation, etc. The results suggest that systems trained with certain genres do not generalize well to others.

description: We argue that Hartle-Hawking states in the Regge quantum gravity model generically contain non-trivial entanglement between gravity and matter fields. Generic impossibility to talk about "matter in a point of space" is in line with the idea of an emergent spacetime, and as such could be taken as a possible candidate for a criterion for a plausible theory of quantum gravity. Finally, this new entanglement could be seen as an additional "effective interaction", which could possibly bring corrections to the weak equivalence principle.

description: Our concern in this Thesis is to study gestures in classic guitar, it covers research made in the Mields of gestures analysis, sensors, gesture acquisition models and guitar gestures. Recent papers and books along with other Thesis are presented as scientiMic background for this project which is mainly inspired by the research of Guitar Lab 1, in fact their gesture acquisition model is used as a starting point, with the goals of (1) improving the gesture acquisition system and (2) get a deeper analysis of gestures that could help Guitar Lab's research towards expressivity. With regard to the gesture acquisition prototype, it is based on capacitive sensors that are able to detect the presence and pressure over a fret of the guitar a brief analysis of the original model is made to demonstrate it's capabilities and its weakness, the capacitive sensors were renewed using new components, an addition to the hardware was made by placing a linear potentiometer that detects the position of the thumb in the back of the neck of the guitar. The renewed prototype was probed and an deep analysis of the achievements and failures of the model is presented. Towards one of the aims of the Guitar lab to use the prototype for an application different to the gesture analysis, we created an augmented guitar using the sensors as controllers to generate sound and trigger music samples.

description: We face a need of discovering a pattern in locations of a great number of points in a high-dimensional space. Goal is to group the close points together. We are interested in a hierarchical structure, like a B-tree. B-Trees are hierarchical, balanced, and they can be constructed dynamically. B-Tree approach allows to determine the structure without any supervised learning or a priori knowlwdge. The space is Euclidean and isotropic. Unfortunately, there are no B-Tree implementations processing indices in a symmetrical and isotropical way. Some implementations are based on constructing compound asymmetrical indices from point coordinates; and the others split the nodes along the coordinate hyper-planes. We need to process tens of millions of points in a thousand-dimensional space. The application has to be scalable. Ideally, a cluster should be an ellipsoid, but it would require to store O(n2) ellipse axes. So, we are using multi-dimensional balls defined by the centers and radii. Calculation of statistical values like the mean and the average deviation, can be done in an incremental way. While adding a point to a tree, the statistical values for nodes recalculated in O(1) time. We support both, brute force O(2n) and greedy O(n2) split algorithms. Statistical and aggregated node information also allows to manipulate (to search, to delete) aggregated sets of closely located points. Hierarchical information retrieval. When searching, the user is provided with the highest appropriate nodes in the tree hierarchy, with the most important clusters emerging in the hierarchy automatically. Then, if interested, the user may navigate down the tree to more specific points. The system is implemented as a library of Java classes representing Points, Sets of points with aggregated statistical information, B-tree, and Nodes with a support of serialization and storage in a MySQL database.

Automatic Recognition of Samples in Musical Audio

Publisher: name: Zenodo
Year: 2011

description: Sampling can be described as the reuse of a fragment of another artist’s recording in a new musical work. This project aims at developing an algorithm that, given a database of candidate recordings, can detect samples of these in a given query. The problem of sample identification as a music information retrieval task has not been addressed before, it is therefore first defined and situated in the broader context of sampling as a musical phenomenon. The most relevant research to date is brought together and critically reviewed in terms of the requirements that a sample recognition system must meet. The assembly of a ground truth database for evaluation was also part of the work and restricted to hip hop songs, the first and most famous genre to be built on samples. Techniques from audio fingerprinting, remix recognition and cover detection, amongst other research, were used to build a number of systems investigating different strategies for sample recognition. The systems were evaluated using the ground truth database and their performance is discussed in terms of the retrieved items to identify the main challenges for future work. The results are promising, given the novelty of the task.

description: En este trabajo nos propusimos analizar el discurso político de Miguel Antonio Caro en sus intervenciones en el Senado de la República entre 1903-1904, a través de un análisis del discurso (texto y contexto), con el fin de develar los aspectos ideológicos de su discurso político y acercarnos a su idea de nación. Para ello, se acudió a la interpretación retórico-discursiva de algunos de los discursos recopilados en el libro Miguel Antonio Caro. Discursos y otras intervenciones en el Senado de la República 1903-1904, publicado en Bogotá por el Instituto Caro y Cuervo en 1979. Para ello, realizamos un análisis de los modos de operación de la ideología y estrategias de construcción simbólica, el significado de “nación” y la construcción discursiva de sus adversarios políticos y del espacio. El análisis del corpus revela que Miguel Antonio Caro representa una legítima oposición al gobierno de facto presidido por José Manuel Marroquín. En su discurso el significado de nación está ligado a los valores morales y a la tradición. Y las estrategias de construcción simbólica que usa están ligadas a la legitimación en su expresión más frecuente: la racionalización. Como es un expresidente que se encuentra en el Senado, se ve en la obligación de legitimar su pasado gobierno y de enfrentar y diferenciar a sus contrincantes políticos que hacen parte del gobierno actual.

description: Core-collapse supernovae, the culmination of massive stellar evolution, are spectacular astronomical events and the principle actors in the story of our elemental origins. Our understanding of these events, while still incomplete, centers around a neutrino-driven central engine that is highly hydrodynamically unstable. Increasingly sophisticated simulations reveal a shock that stalls for hundreds of milliseconds before reviving. Though brought back to life by neutrino heating, the development of the supernova explosion is inextricably linked to multi-dimensional fluid flows. In this paper, the outcomes of three-dimensional simulations that include sophisticated nuclear physics and spectral neutrino transport are juxtaposed to learn about the nature of the three dimensional fluid flow that shapes the explosion. Comparison is also made between the results of simulations in spherical symmetry from several groups, to give ourselves confidence in the understanding derived from this juxtaposition.

title: Partitioning algorithms for induced subgraph problems
Creators: name: Trimble, James
Publisher: name: University of Glasgow
Year: 2023

description: This dissertation introduces the MCSPLIT family of algorithms for two closely-related NP-hard problems that involve finding a large induced subgraph contained by each of two input graphs: the induced subgraph isomorphism problem and the maximum common induced subgraph problem. The MCSPLIT algorithms resemble forward-checking constrant programming algorithms, but use problem-specific data structures that allow multiple, identical domains to be stored without duplication. These data structures enable fast, simple constraint propagation algorithms and very fast calculation of upper bounds. Versions of these algorithms for both sparse and dense graphs are described and implemented. The resulting algorithms are over an order of magnitude faster than the best existing algorithm for maximum common induced subgraph on unlabelled graphs, and outperform the state of the art on several classes of induced subgraph isomorphism instances. A further advantage of the MCSPLIT data structures is that variables and values are treated identically; this allows us to choose to branch on variables representing vertices of either input graph with no overhead. An extensive set of experiments shows that such two-sided branching can be particularly beneficial if the two input graphs have very different orders or densities. Finally, we turn from subgraphs to supergraphs, tackling the problem of finding a small graph that contains every member of a given family of graphs as an induced subgraph. Exact and heuristic techniques are developed for this problem, in each case using a MCSPLIT algorithm as a subroutine. These algorithms allow us to add new terms to two entries of the On-Line Encyclopedia of Integer Sequences.

description: Evolved stars are crucial pieces to understand the dependency of the planet formation mechanism on the stellar mass and to explore deeper the mechanism involved in star-planet interactions. Over the past ten years, we have monitored about 1000 evolved stars for radial velocity variations in search for low-mass companions under the Penn State - Torun Centre for Astronomy Planet Search program with the Hobby-Eberly Telescope. Selected prospective candidates that required higher RV precision measurements have been followed with HARPS-N at the 3.6 m Telescopio Nazionale Galileo under the TAPAS project. We aim to detect planetary systems around evolved stars to be able to build sound statistics on the frequency and intrinsic nature of these systems, and to deliver in-depth studies of selected planetary systems with evidence of star-planet interaction processes. For HD 5583 we obtained 14 epochs of precise RV measurements collected over 2313 days with the Hobby-Eberly Telescope (HET), and 22 epochs of ultra-precise HARPS-N data collected over 976 days. For BD+15 2375 we collected 24 epochs of HET data over 3286 days and 25 epochs of HARPS-S data over 902 days. We report the discovery of two planetary mass objects orbiting two evolved Red Giant stars: HD~5583 has a m sin i = 5.78 M$_{J}$ companion at 0.529~AU in a nearly circular orbit (e=0.076), the closest companion to a giant star detected with the RV technique, and BD+15~2735 that with a m sin i= 1.06 M$_{J}$ holds the record of the lightest planet found so far orbiting an evolved star (in a circular e=0.001, 0.576~AU orbit).

description: Electroencephalogram (EEG)-based Brain-Computer Interfaces (BCIs) have garnered significant interest across various domains, including rehabilitation and robotics. Despite advancements in neural network-based EEG decoding, maintaining performance across diverse user populations remains challenging due to feature distribution drift. This paper presents an effective approach to address this challenge by implementing a lightweight and efficient on-device learning engine for wearable motor imagery recognition. The proposed approach, applied to the well-established EEGNet architecture, enables real-time and accurate adaptation to EEG signals from unregistered users. Leveraging the newly released low-power parallel RISC-V-based processor, GAP9 from Greeenwaves, and the Physionet EEG Motor Imagery dataset, we demonstrate a remarkable accuracy gain of up to 7.31\% with respect to the baseline with a memory footprint of 15.6 KByte. Furthermore, by optimizing the input stream, we achieve enhanced real-time performance without compromising inference accuracy. Our tailored approach exhibits inference time of 14.9 ms and 0.76 mJ per single inference and 20 us and 0.83 uJ per single update during online training. These findings highlight the feasibility of our method for edge EEG devices as well as other battery-powered wearable AI systems suffering from subject-dependant feature distribution drift.
Detection of genre-specific musical instruments: The case of the mellotron

Publisher: name: Zenodo

description: When facing the problem of organizing, categorizing, browsing and retrieving data from large music collections, musical instruments play a predominant role, as they define the timbral qualities in any piece of music. Recent technological developments in digital audio have made possible to automatize these tasks. Specific instruments can also be directly related to concrete musical genres, which increases the possible applications of such systems. This document addresses the problem of detection of musical instruments in polyphonic audio, exemplifying this specific task by analyzing the mellotron, a vintage sampler used in popular music. The mellotron presents interesting technical and perceptual qualities, which make it ideal for the study of timbre descriptors in the context of automatic classification in polyphonic audio. For accomplishing this task a novel methodology is presented, based on the idea that it is possible to train classifiers with audio descriptors (temporally integrated from the raw feature values extracted from polyphonic audio data) using extensive datasets. A series of experiments were designed in order to gather information about the specific descriptors that could help accomplish the detection and classification tasks, by employing custombuilt datasets classified according to instrumentation features. Several machine learning techniques are tested and evaluated according to the effectiveness of the system, that is, performance based on the accomplishment of the objectives by selecting different measures. The results obtained were relevant for the tasks proposed, with values far above chance in most cases, which indicates some statistical significance for assuring that the models tested are indeed recognizing the presence of the mellotron in a polyphonic context. The evidence shows that the methodology used proves to be effective for solving the task.

description: Erasmus University Rotterdam has used the issue of open access as an opportunity to engage with researchers, finding new ways of helping them to share their work with the world. Erasmus — ranked globally among the top 100 universities — is among a growing number of institutions worldwide that is committed to data sharing and open access (OA) research. Erasmus’s policy is that all short scientific work must be published in an OA journal or deposited in an institutional repository. As an important part of that commitment — and to cope with the growing amount of research content — the Dutch university established the EUR Data Repository (EDR).

description: We introduce a new aspect of nonlocality which arises when the task of quantum states distinguishability is considered under local operations and shared entanglement in the absence of classical communication. We find the optimal amount of entanglement required to accomplish the task perfectly for sets of orthogonal states and argue that it quantifies information nonlocality.

Extending the control of a musical tangible tabletop with mobile phones
Creators: name: Katsaprakakis, Alexandros
Publisher: name: Zenodo
Year: 2011

description: This project proposes the use of the sensory features of modern mobile phones that were previously unavailable for the wide consumer public, such as the accelerometers and the multi-touch surfaces, as an input for a musical tangible tabletop. The development of a mobile application operating simultaneously with the reactable is carried out based on a conventional wireless connection. The application is a formant voice synthesizer controlled by both the mobile device and the reactable. The proposed system seeks to give an additional degree of freedom in the musical experience and expression with this instrument and tries to take advantage of the advancing mobile technology to extend the control of the reactable and provide alternative ways of musical interaction.

description: Generative language models hallucinate. That is, at times, they generate factually flawed responses. These inaccuracies are particularly insidious because the responses are fluent and well-articulated. We focus on the task of Grounded Answer Generation (part of Generative IR), which aims to produce direct answers to a user's question based on results retrieved from a search engine. We address hallucination by adapting an existing genetic generation approach with a new 'balanced fitness function' consisting of a cross-encoder model for relevance and an n-gram overlap metric to promote grounding. Our balanced fitness function approach quadruples the grounded answer generation accuracy while maintaining high relevance.

The EyeHarp: A Gaze-Controlled Musical Instrument
Creators: name: Vamvakousis, Zacharias
Publisher: name: Zenodo

description: In the thesis, we present the EyeHarp, a digital musical instrument based on eye tracking. The EyeHarp consists of a self-built low-cost eye-tracking device which communicates with an intuitive musical interface. The system allows the performer to produce music in real time by controlling sound settings and musical events only through eye movements. The instrument can also be controlled using any input device that can take control of the mouse pointer, and thus it could be appropriate for many cases of people with disabilities. Following the EyeWriter' s initiative instructions, a €50 eye tracking device was constructed and used along with the provided open source code for getting the user's gaze coordinates on the screen. Having that as an input, the EyeHarp digital musical instrument was implemented in openFrameworks C++ toolkit. The user can play music in real time controlling the chords and melody of his composition through an intuitive interface based on the pie menus. On top of it, an arpeggiator machine and a step sequencer provide the opportunity of creating a harmonic and rhythmic background. Depending on the desired task, dwell time or screen button gaze selection technique is applied. A preliminary discount usability experiment is conducted having the eye gaze versus the head movements as input.
Interactive music system based on pitch quantization and tonal navigation

description: Recent developments in the field of human computer interaction have led to new ways of making music using digital instruments. The new set of sensors available in devices such as smartphones and touch tablets propose an interesting challenge in the field of music technology regarding how they can be used in a meaningful and musical way. One to one control over parameters such as pitch, timbre and amplitude is no longer required thus making possible to play music at a different level of abstraction. Lerdahl and Jackendoff presented in their publication “Generative theory of tonal music” a perspective that combines Heinrich Schenker’s theory of music and Noam Chomsky linguistics to explain how tonal music is organized and structured. This idea opens up the possibility of investigating ways to manipulate a “wider” aspect of music through an assisted interactive musical system that takes into account the “principles” or common knowledge used in music composition and performance. Numerous publications exist in the field of music theory regarding how the tonal aspect of music works. Due to aspects related to psychoacoustics and cultural inheritance, there is a certain common base on how to form and use chords and scales, and how they are organized in terms of hierarchies, movement tendencies and tonal functions. This project deals with the design of a graphical representation about the use of tonality in jazz and popular music, organizing chords and scales in a hierarchical, semanticall and practical way. This representation, which we call “Tonal map”, is then used as the graphical interface of an interactive system to manipulate different data types in realItime. The process consists in adjusting note values (pitches) using a set of rules that characterize each sector of the graphical representation. The output produced by system is the “tonally quantized” version of the input data using as transformation parameter the set of rules that the user chooses through the graphical interface. The graphical model was constructed using different methods for learning modern harmony and taking also into account models of music perception and cognition. The interactive system was implemented through a Max for Live patch that works as a MIDI effect. Input data is first transform into MIDI note events that are modified according to the users selection in the tonal map. The hardware interface uses a Wacom tablet with a printed version of the tonal map. The interaction can be seen as a tonality selector for real time transformations of MIDI data. The prototype can also be used with several inputs at the same time allowing collaborative playing
