Ramp Tree proof of concept is working now! These stupid sine chirps are a beautiful sound this morning after days of work.
What's going on: an external phasor signal (period ramp going 0-1) is going into the Ramp Tree, and the Ramp Tree is dynamically subdividing the phasor signal by analyzing and resynthesizing a new version.
To use some musical terms, what comes in as a signal pulsing at quarter notes comes out shaped as a 3/4 rhythmic phrase (1 measure): 2 eighth notes, a quarter notes, followed by 3 eighth note triplets.
The next step is to use these ramps as alpha values for linear interpolation. Then it'll be a real gesture!
gestures synthesizer updates
I added "step" behavior to make gestures sound more like a traditional step sequencer. Also makes it easier to debug.
I also implemented monoramp transformation.
So, if a polyramp takes a single 0-1 ramp and divides it into N equal steps, a monoramp takes N ramps and merges it into 1 ramp. From there, a polyramp could be applied to it, creating arbitrary divisions of rhythm.
This gesture example features two eighth notes, followed by a set of quarter-note triplets.
The quarter note triplets were made by creating a monoramp from 2 beats, then converting that monoramp into a polyramp of 3 beats.
I let the last note have linear behavior so it could dynamically gliss back into itself.
