thanks for stopping by! 🙂
The factory firmware is the NS1NANOSYNTH_BASE_NO_DIGIPOT. As the name states, the four digital potentiometers are not active because of an incompatiiblity between the MOZZI library (that is inserted just as an example, generating a saw wave related to the MIDI note on the M–> pin)and the i2c (wire.h) lib.
To gain the midi control change to digital potentiomenter function we wrote the other firmware that gets rid of the MOZZI libraries and implement this very nice MIDI integration function..
Please take a look at the other threads in this forum as there are three or four notable alternative firmwares with source code and also instruction on how to load libraries etc….
