This board is most usable in organ emulators for stops/pistons control. It takes care of 24 contacts and every one of them is paired with LED driver. This is to enable the use of momentary normally-open switches to work as bistable lighted stops/pistons. One press of a button lights up associated LED, and sends appropriate message to the main MIDI controller. Next button press turns the light off and again sends the message to MIDI controller. Part of the inputs can be assigned to work in 1-of-many mode, where pressing one button light up associated LED, and turns off the other ones in the group. Although most intended for stop control, it can be used as any other scanner/expander

Features:

• scans 24 contacts
