Analog GAS

[GoldenVulture]

I'm pretty basic with the left hand myself but my piano and most uprights had a sustain and a soft pedal. The sustains had a lot more variation than an elctronic one does in most cases. Using the two was pretty easy but I didn't find a lot of use of the soft pedal.
I modded my polySix so I had a foot pedal control on the release control in the envelope section. Essentially gives you a massively variable sustain from chopped short/ no sustain to continuous sustain and all inbetween. It's just a pot in a wah pedal housing. I put in a stereo jack at the back that cuts out the on synth control when the pedal cord is plugged in.
I had to insulate it all from everything else as the cable uses all three connects passing voltage as it is voltage control parameter electronically
