Caustic Song file (optional):
Word of warning: my poor little phone screams in agony every time I press a key on this thing, but I've exporting minute long chunks out of it all day with no problems. Your results may vary.
So what we have here is a 14 machine modular set up. The first three machines act as control devices for the remaining eleven tone generators. Each of those tone generators consists of six waveform generators, a DADSR envelope, and a 6 input mixer. The outputs of the eleven are collected in the third machine "inputs". The signal is then passed to the first machine "mod 1" which has an assortment of filters, effects, and other goodies. "Mod 1" is the main output, all the actual tone generators can have their channel volumes turned down completely (though in the uploaded file I did leave #1 turned up a little with lots of delay just to give some ideas). The "Arp" machine is just an arppegiator, with room for extra goodies if you so desire.
Effects wise, I went with a phaser and flanger on the output and distortion and chorus on the master to go along with the built in reverb, delay, parametric eq, and limiter. The whole thing can be played with the "mod 1" or "arp" keyboards.
As uploaded, it's playing a random arppegiator across all machines. You could also save the patch on one of the tone generating machines as a preset, load that preset on to the other ten tone generators, turn off the arpeggiator, and suddenly the whole thing becomes a six oscillator multi-filter synthesizer with 11 note polyphony (program each of the eleven notes on different tone generators). For the record, the "6 OSC" preset is just six wave generators, the envelope, and mixer wired together as shown without any further editing from their default settings.
Lots of experimentation available here. As an example, what would happen if you dropped a wave generator from each of the machines and put in an lfo and pan module? What if each machine consisted of two three oscillator FM chains? And so on and so on.
