I can already see multiple banks as useful. 16 knobs and switches should allow for a comprehensive mixer control. Perhaps a bank for sequencing and one for filter control. It might take a bit of effort to set up all the mappings but I think it will definitely be worth it. Although you could certainly map as you go, I think some premapped templates might be useful. I see one with a mixer, a set of outputs for sequencing, a set for filters and one for whatever (tempo, on/off etc.). It’s flexible enough to handle everything but actual keyboard/drums type input. This and a MIDI keyboard would be an awesome combo for Audulus input.
