Would really appreciate some help. I want to build a synth where each tone generator/oscillator module has waveform selectors in the form of 6 toggles and a horizontal slider with 6 values, ranging from (left to right) my saw(ramp down), square, rev. saw(ramp up), triangle, sine, and noise~. I have other things I would like to modify like making the oscillators polyphonic, pulse width, modulating crossfader and other params, etc. this crossfader seems to be a unique and difficult task for a noob like myself.

img of patch attached, i welcome any other thoughts as well. obviously i know only one osc is connected to dac~ in my img.

Many thanks
