Question: The drum software synthesizer "Superior Drummer" is compatible with what modern electronic musical instrument that consists of an electronic or digital sound module and can be struck by sticks or by the hands?
Context: A MIDI controller is any hardware or software that generates and transmits Musical Instrument Digital Interface (MIDI) data to electronic or digital MIDI-enabled devices, typically to trigger sounds and control parameters of an electronic music performance.  The most commonly used MIDI controller is the electronic musical keyboard MIDI controller, which has keys that can be pressed.  When the keys are pressed, the MIDI controller sends MIDI data about the pitch of the note, the velocity and duration, which can be used to trigger sounds from a MIDI-compatible sound module or synthesizer. Hit Stix is a toy electronic musical instrument manufactured by Nasta and Radio Shack in the 1980s.  A set of Hit Stix consists of 2 drum sticks which are tethered to a small amplifier by audio cables.  When the drum sticks are thrust forward in mid air, mimicking actual drum playing, a snare drum sound effect is produced.  A rapid succession of thrusts produces a drum roll.  It is a common misconception that Hit Stix are meant to be hit against another surface.  In fact, the sounds are produced simply by the motion of drumming and do not need to come in contact with any surface in order to produce a sound. Superior Drummer 2.0 is a sample based drum software synthesizer developed by Toontrack, similar to previous software such as Drumkit from Hell, but with a complete overhaul of the original Drumkit from Hell Superior engine.  The software has been re-developed for optimised use with electronic drum kits with more effective use of sample layers and much improved loading times.  The software comes with multiple built in fx such as a 5 band EQ, High-pass and Low-pass filter, compressor, gate and a transient design filter. An electronic drum module is an electronic or digital music device in an electronic drum kit that serves as the central processing unit and sound module.  The drum module creates or produces the drum kit sounds or other sounds selected by the drummer.  By itself, a drum module cannot play or sound drum beats.  It only produces drum sounds when a performer strikes electronic drum pads or acoustic drum kit instruments that have electronic "triggers" (or sensors) attached to them.  When the electronic drum pads or trigger-equipped instruments are struck, this sends a signal to the drum module, which produces the corresponding electronic drum sound (or other sound).  Even when drum pads and/or triggers are connected to a drum module, the drum module by itself does not make any audible sound.  Like other electronic instruments such as the synthesizer, the drum module only outputs an electronic signal.  The performer can hear this signal by connecting headphones to the drum module (i.e., for individual practice) or by plugging the drum module into a amplifier and loudspeaker or PA system for audible practice or live performances.  The drum module's output signal can also be patched into an audio console for concerts or sound recording.  The nomenclature varies (see below).  For example, electronic drum modules are called "percussion sound modules" in the case of Roland Corporation, or sometimes simply modules.  A common colloquial term for this device is drum brain.  (see below). EZdrummer is a sample-based drum software synthesizer developed by Toontrack.  It is a simplified version of its predecessor, DFH Superior.  EZdrummer is based upon approximately 7000 16-bit 44.1 kHz samples of real drum kits.  EZdrummer contains a mixer that allows the user to adjust the independent volumes of each of the microphones on the drum kit.  EZdrummer also comes with approximately 8000 MIDI drumloops that can be directly drag and dropped.These loops are tempo-synchronized and volume-adjustable. A digital piano, also known as piano synthesizer, portable piano, weighted keyboard, or in the late 1980s, personal electronic piano, is a modern electronic musical instrument; a variation of electronic keyboard or synthesizer designed to serve primarily as an alternative to the traditional acoustic piano, both in the way it feels to play and in the sound produced.  It is intended to provide an accurate simulation of an acoustic piano.  Some digital pianos are also designed to look like an acoustic piano, both the upright or grand piano body style.  Digital pianos use either an electronic synthesized emulation of the piano sound or a sampled piano sound, which is then amplified through an internal loudspeaker.  Digital pianos typically have weighted or semi-weighted keyboards, which attempt to recreate the feel of an acoustic piano. An electronic musical instrument is a musical instrument that produces sound using electronic circuitry and/or digital devices.  Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and/or listener. An electric musical instrument is one in which the use of electric devices determines or affects the sound produced by an instrument.  Electric musical instruments are an example of electric music technology.  It is also known as an amplified musical instrument due to the common utilization of an electronic instrument amplifier to project the intended sound as determined by electric signals from the instrument.  Two common types of instrument amplifiers are the guitar amplifier and the bass amplifier.  This is not the same as an electronic musical instrument, like a synthesizer, which uses entirely electronic means to both create and control sound. A sound module is an electronic musical instrument without a human-playable interface such as a piano-style musical keyboard.  Sound modules have to be operated using an externally connected device, which is often a MIDI controller, of which the most common type is the musical keyboard (although wind controllers, guitar controllers and electronic drum pads are also used).  Controllers are devices that provide the human-playable interface and which may or may not produce sounds of its own.  Another common way of controlling a sound module is through a sequencer, which is computer hardware or software designed to record and play back control information for sound-generating hardware (e.g., a DJ may program a bassline and use the sound module to produce the sound).  Connections between sound modules, controllers, and sequencers are generally made with MIDI (Musical Instrument Digital Interface), which is a standardized protocol designed for this purpose, which includes special ports (jacks) and cables. An electronic drum, also known as digital drums or digital percussion, is a modern electronic musical instrument, a special type of synthesizer or sampler, primarily designed to serve as an alternative to an acoustic drum kit or other percussion instruments.  An electronic drum consists of an electronic or digital sound module which produces the synthesized or sampled percussion sounds and one or more electric sensors to trigger the sounds.  Like regular drums, the sensors are struck by drum sticks or by the hands (depending on the type of drum pad) and they are played in a similar manner as an acoustic drum kit.
