Multi Timbral Setup for Step B

From the Step B page

Note: the PIC18F implementation of MIDIbox SID allows to split the voices over different keyboard zones, so that up to 12 voices can be played and layered individually.

Does this mean multitimbral setup?  Octave 3 is sid 1, octave 4 is sid 2, etc.. ?

I’m so stupid, i pose my questions, then i spend 9 hours, and then i find the answers by accident..

Regardless, i have a control surface A now that completely works!  i have set up multitimbral settings for a single sid, i bet for multi sids that’s not hard.. so amazing..
