I’d like to make a playable 3x Oscillator in Max. The basic functionality will be three separate oscillators with switchable waveforms which can be (de)tuned and volume adjusted separately. On top of hooking this up to a keyboard (and maybe functionality to have it read from USB Midi input?) I could also implement a bunch of user-customizable options like hi/lo pass filters, panning, reverb, and EQ options. I could also add some visualizations of the resulting waveform.
