i ask you if you have any idea of where my problem is located, and if you have any solution. i verify a lot of solders, but can't find any mistakes.
the lowest note of my sequencer begin in A0, instead of C-1....when i play note G#0, it sounds very high, and when i play the next one, A0, it plays a very low note.
the range of the pitch is note "center" as it must be.
i'm lost with the schematics, i don't know what gives the initial pitch.....
thank you for any help.
