Hello everybody,
I'm new here and an absoute beginner to the programming of the teensy, but quite an expert at soldering etc. I should say that English is not my first language and I do apologize if I do not adopt the right tone sometimes.

I've got a commercial MIDI foot controller that sends program changes. I would like to add an expression pedal that means the teensy should convert 0-5 volts into MIDI CC 0-127 without jitter. Secondly, the teensy should be able merge the generated CC message with the incoming program change messages from the existing MIDI foot controller.

What kind of teensy hardware do I need? It does not seem to be such a big job for the teensy.
I guess the code required may already exist, too.
Could someone point me in the right direction, please?

Kind regards and stay at home programming and soldering ...
