Discussion: Filter Section

[billvanloo]

During the last work session with @joebauer and @thynk we discussed a few possible changes to the filter section.

1. We discussed adding back the resonance control, since we're moving to the MUX board which gives us additional inputs.
2. We also discussed the possibility of adding a second filter section, so the instrument would have both lowpass and highpass filters as separate filters. These could be combined to create a bandpass effect. These would have separate cutoff controls, and could either share a common resonance control or have their own resonance controls.
3. We also discussed the possibility of moving from the DJ-style filter control (where it's a lowpass when turned to the left, or a highpass when turned to the right) to using a selector switch of some kind to switch between different filter types (lowpass, bandpass, highpass). In my head, I'm envisioning something like what the Jove filter uses:

I think I might be leaning more to option #3, but perhaps with the selector being another knob (one I/O used vs. 4?)?
