The E330 is a digital oscillator with three very different synthesis methods and two voltage controllable "effect inputs". The audio signal is emitted at two outputs.
The three modes of the E330 are:
2OP FM: classic Yamaha sine operator/carrier, outputs 90 degrees in phase apart. VC'd FM Index range of 0 - 300%. VC'd FM Ratio from 0 to 7.125 in steps of 0.125 (1/8 ratio).
MORPH: 32 E350 'best of' wavetables in a Z MORPH setup. The 2 outputs have independent waveform outs (same frequency), each CV controls the waveform output for that channel.
CLOUD: a subset of the E340, it has sine and saw outputs using a fixed 4-VCO detuning. Independent SPREAD and CHAOS CVs. The CHAOS is a combination of the E340 CHAOS and CHAOS BANDWIDTH
