Low Frequency Expander using MPE to control OB-6's pitch, sync and filter, changing clock divisions

video by Steve Hunt

"Demo 4 of the LFE using Midi Polyphonic Expression (MPE) to modulate each of the synth's 6 voices independently. This also works for the Prophet 6.
LFO1 square wave controlling pitch of VCO1 and 2 stepping an octave.
LFO2 square wave controlling filter cutoff running at a faster clock multiple.
LFO3 ramp up/tri/ramp down controlling VCO1 frequency, sync making the classic sync sound.
Each LFO is sync'd to the synth's clock and has its own clock divisor so they can make crazy synchronised patterns.
Later I turn on the synth's delay and play with its clock divisor, also sync'd to the same clock.
MPE allows each of these 3 LFOs to run a separate LFO for each of the synth's 6 voices, so that's 3 x 6 = 18 LFOs running together. There's actually an extra set of 3 global LFOs and 7 envelopes that I'm not using in this demo."
