CTM64
The counterpart to MTC64 is the Contact To MIDI interface CTM64 that converts up to 64
free contacts into 64 succeeding note or program change messages. Closing a contact
connected to the CTM64 causes the transmission of the corresponding MIDI note or program
change message. CTM64 can be used to retrofit keyboards, switches, button arrangements
or any other types of contactes with MIDI out.
A typical application of CTM64 and MTC64 is the following:
Contacts → CTM64 → (Computer-Sequencer) → MTC64 → lamps/relays/electromagnets
This arrangement can be used to record any contact operations with a computer sequencer
and play it back later to lamps, relays, magnetic valves, motors and so on. If recording is not
required the sequencer can be omitted:
Contacts → CTM64 → MTC64 → lamps/relays/electromagnets
