Or is there a better solution when working with a large set of LEDs like this?
Is there a way I could tap into this harness and capture the key strokes on the way to the midi output in order to manipulate it?
However, it would be very simple to wire up a din input to the Arduino itself and bypass the USB altogether.
I could add some potentiometers and switches to do arpeggios and control the tempo,
Would it?I remain to be convinced of that, it is not the way things usually work.
Worst comes to absolute worst, I can leave the internals of the keyboard in tact and mount the midi breakout board I/O on the back of the keyboard and take the existing output to the new input and then out again from there to whatever I want to control.
Are you trying to hold out so i buy your book?
Where is your concern at with it?
