FM Polynator V1
Polyrhythmic FM Drum Machine
Polyrhythmical Quadphonical FM Modulor
File this one under "ensembles I'll never finish" but thought I'd share it. Its a version of my Triphonic FM Modulor ensemble:
This ensemble is different in that its made as a drum machine - sync-able to the tempo - and has 4 FM oscillators modulating each other instead of 3. Top left modulates top right, top right modulates bottom left, bottom left modulates bottom right, and bottom right modulates top left. Its like Human Centipede but for FM modulations.
Each oscillator has a Filter, an Envelope, LFO, and a Sequencer.
The sequencer is done by making each FM Oscillator have a different speed based on different subdivisions of a measure. So one synth could be going at 1/32 repeating, the other at 3/24, and so on.
The sequencer is an XY grid:
- X axis controls the type of subdivision (2, 3, 4, 6, 12, 16, 24, 32)
- Y axis controls how many of those subdivisions (1, 2, 3, 5)
So, when Y = 2 and X = 12, its two 12th notes repeating. Y = 3 and X = 32, its three 32nd notes repeating.
I made an annoying knob for the LFO which only shows the type of LFO (Sine, Tri, Sqr). It works, but its weird.
I've included a bunch of random presets , plus a "RANDO" button that randomizes everything.
Each oscillator is being panned with an envelope of one of the other oscillators, so its very stereo. Unchecking the "Stereo" button will make the drum machine sound in mono.
Its not great, but can make some fun sounds & beats!
