Is it possible to satisfy the input offset and output slew knobs/pots with
programmable offset and slew?  

If slew is only used to prevent zippering, then a digitally set programmable
slew per output seems much easier, repeatable, plus saves panel space.

Input offset might be a little more difficult, depending on the usage.  If
only used to change from 0-10 volt range to +/- 5V range, then a
programmable function is easy.  If used to tweak the nominal value of a
function, let's say four voltage controlled LFOs, then it becomes a
necessity.  Opinions appreciated, especially from those who have wired this
function in their PSIM and used it.

I could personally do without MIDI, but it seems that a lot of people want
this feature.

If we were to take a poll, I'd guess that most people would vote for all the
features but want it in a 2U MOTM or standard width Frac Rack panel...
