I have finally built my Shruthi, apparently everyting is ok, 90%
I have successfully built the firmware and apparently it uploads with no errors, using a usbasp programmer
Seems to be mostrly working (MIDI in is OK; I can change presets and play with it)
But when I turn the pots like Cutoff or Resonance, the value on screen change, but there’s apparently no change in sound…and then the value reverts to the original value (128)
or, another example, I set attack to 0 decay to 0 and so on, nothing changes in soud and then sthe atk-dec-sus-rel showas all values at 128…
firmware issue or hardware issue?
