Maps w/ Trent: Harmonics, Subharmonics, and everything *just* in between
Channel: Trent

Capture of the twitch stream from 5/14.

Starts with an exploration of harmonics, aka overtones, in the context of synthesizers. Demonstrating how the series can be recreated with a filter near self-oscillation, or using two oscillators in a soft-sync configuration.

Then we outline the subharmonic series using Mangrove's Formant & Barrel behaviour, followed by two different methods with the Just Friends module. Lots of techniques are demonstrated for different patch configurations.

Finally we get into recreating these effects with Crow, and write a script that allows dynamic control over both the harmonic and sub-harmonic series simultaneously.

The second hour starts with exploring the 'Just' ratios created by this crow script. These are explored in a sequencer with 'slew' added, which steps through the ratios in an integer-wise manner. This section gets a bit complicated with the slew section, but comes through in the end.

By the end we create a sequencer that steps through *overtone* and *undertone* values independently, and finally places the stepping of each into it's own timer for doubly-phasing ratios. It gets a bit cacophonous at times, but there's some magical moments to be found!
