I finished my first own MIDI-Controller with the Brain Jr. Works like a blast, only glitch I have is that the encoder I use on 8+10 gets into conflict with two buttons i have on 9+11 the other encoders are on 12+14/13+15. Anyone had this behavior? When I enable the encoder on 8+10 the two buttons turn into an encoder as well. Other than that - I am quite happy. I tried to get the most out of all the available inputs and managed to use every single one of them:
2 pots
3 Faders
3 Encoders
4 Switches
14 Buttons with LED Feedback
2 Status LEDs
ps: Livid, your headers are super tiny and unconventional, that makes some things a bit hard to solder.

Looks Great!
I'm thinking you may try putting a diode on the (-) row side of each button or encoder pin that is giving you trouble.
thank you for the response. what kind of diode would you recommend?
This is the part # we use from Mouser.com
1N4148TR
Looks great! i wouldn't solder to the headers of the Brain, try the breakout shield for solder holes.
thanks for the part no. I will give this a try and let you know how it works out :)
god job! looks really cool. I like the switches in rectangular form with led (he ones in colors) Remember me the "avolites buttons" ,, can you tell me the Tecknical name of this switches?? i will try to buy some but didnt find they.
