I have build up a Shruthi 1 XT PCB. I flashed the actual software 1.02 with avrstudio.
Triggered the Shruthi with my midi keyboard gives a bad tone out of it and display always shows up -> a ! (means ! The Shruthi is busy accessing memory - this can interrupt sound generation)
When I rotate i.e. a cutoff pot the display flips also back to 128 value. It always has the same sound.
someone who knows this problem ?
