Shruthi XTC as a controller for Ambika

Discontinued DIY products
#1

I’m building both a Shruthi XT and an Ambika, and wondering if I plug Shruthi Midi Out to Ambika Midi In, and a keyboard to Shruthi Midi In, will that allow patch editing on the Ambika with the Shruthi XT Pots?

And… if so, would a cut down Shruthi XT, with no Voice cards / LCD work as a simple patch editor for Ambika?
It would cut cost in half If I were to build another solely for that purpose

#2

No, the voice structure of Ambika and Shruthi is different from each other. Consequently, also the MIDI CC mappings are not compatible.

#3

a kit like 60 knobs might be more what you want.

#4

Well the shruthi XT layout is really nice, plus I’m building one anyway.
Being that the Ambika has all the same parameters, and it can receive midi CCs for those parameters, and the Shruthi sends midi CCs for it’s knobs, can I just modify firmware of one of them so the CCs match?

Could I just edit this table?
