ChrisTenone:
Your title should mention MIDI
I posted a topic in the "Project Guidance" forum about this, that described the project in the title (got no replies), but this thread was originally about the LEDs and resistor question.. I didn't intend to get this far into the overall project in this thread, but it sorta morphed.. 
Grumpy Mike pretty much answered my question about feasibility, so I don't really need an answer on that other thread now anyway.. Probably won't get too far into the thing here in this one either..
From here on, the electronics/hardware is pretty straightforward (at least until I get into putting together the UI).. Where I'll need a 'ton' of help is in the code, so when I get there, I'll start a new thread and that will mention MIDI controller in the title for sure..
