I’m a +1 for a Unison mode or two ( ex: 4 voice unison w/detune .3 voice with detune and 4th voice becomes a sub , perhaps even a duphonic unison too ?
I’d love to see a dedicated PWM Saw oscillator ... mmmm
A minibrute
or a Juno type Osc with multi waveform and sub Osc mixing .
Since the vocoder ...why not just have an external input mode too to use that tasty filter and mods on other sound sources ?
