…after the suggestions (thanks Wesley) I redesigned the nanodrum:
- without Arduino
- 24 inputs
- MIDI IN and MIDI OUT
- simple direct connection with LCD, 2 buttons and Wav Trigger
- expansion connectors
- shift register for the LCD (3 free digital inputs)
- USB port (for MIDI and firmware upload)
and therefore I propose again the idea of collecting funds to print the first PCBs. The use of the shift register is well documented on the internet then it will work right away, instead firmware USB-MIDI will need more time to be completed. Currently we can use the firmware MICO-MOCO that has some limitations but it works. When the MIDI-USB firmware will be complete I realize a new version of microDrum, for now I will test it only on nanoDrum.
Unfortunately with the new components, the cost rises. For the phase of fundraising I set the price at 60 €.
