Defender Panel Redesign

No, don’t panic, the panel layout is staying the same. What is changing is the backend for the panel, I had numerous problems with the first revision of the panel control board, mostly with it talking to the main CPU board and then the voice.

So, I’ve shrunk things, the panel board now controls the voices, handles MIDI and will handle patch storage. This all fits onto a 100 x 80 mm PCB (I love surface mount). Below is the PCB almost assembled (I’m missing the pull ups for the switches). I have two of these and I’m sure the other will come in useful soon for something.

Below is the current PCB in situ, I plan to rewire this to the new panel PCB soon.
