How many MIDI notes can I get out of Brain Jr.?
I bought a Brain Jr to build a MIDI foot controller, but in the process came up with an idea to build an isomorphic keyboard as well. Is it possible to get more than 32 notes out of a Brain Jr (I'm assuming I can use all the digital and analog I/O's for notes, though i'm not sure how to wire a push button to the analog section at the moment). Would there be a way to add octave buttons? Perhaps Transpose buttons? I want some help understanding the limitations of the Brain Jr before I start making my plans for building this.

You can wire buttons to analogs, so you can get 32 notes. The transposing would have to be done with software.
Button Mode Allows you to connect a button as an Analog Control. To connect a button as an analog:
1. Connect 1 side of the button to Analog Power (pin 2 of any Analog pin header)
2. Connect other side of the button to Analog Signal (pins 3-10 of any Analog pin header).
3. Connect a 10k resistor between the Analog Signal and Analog Ground (pin 1 of any Analog pin header).
