Pressing a key depresses the tactile button and we get a note-on signal. The bottom of each key has a raised area that makes contact with the tactile switches that are the actual key switches beneath the keybed. There are no return springs beneath the keys, they simply use a "living hinge" (oh how I dislike those things, they NEVER live very long). You can see they come in octave chunks, and with a single "C" key to fill in the end gap and create an even number of C-C octaves. It's interesting to see how manufacturers buy these little keybeds. ).Ī few screws and the keybed chunks come right out. I used an Alesis Micron as a keyboard controller, connected it's midi out to the MicroBrute's midi-in.
I then tested the synth's functions with the keybed disconnected. There now, there's nothing else between the keybed and the rest of the synth. Carefully remove the connector from it's socket.
Keybed is attached to main pcb via a very small and very delicate ribbon connector.
