Planning (delayed indefinitly due to expensive)

The interface for the ?sequencer? is going to be a grid of buttons. The intended effect is that you could tap in a beat, and it records the pattern and timing. and then play it in a loop autominiously. I intend to use arduino to control this segment of the instrument. as the requirement to implement would be minimal and would a 9v battery to power it. the only possible issue will be the speed of it descerning input. and the subsequent fine tuning of playback.

this will trigger a parrallel switch with a reed relay to shut the circuit.

During playback, led's will light up on the corresponding button. 4 leds to indicate what status the module is in idle, recording, playing, and stalled (when both activation switches are engadged).
