What it’s all about? is, every row of the seq-3, has 3 oscillators with different octaves and different semi octaves. as you can see on the title? 9 VCO’s means 9 oscillators. and what’s that mean? is, every 3 oscillators will run through the sequencer row, and if you change the forms on the mixers (not the master mixer)? you will make a cool difference i guess if so!
forms i ment waveforms.
