The MLRT-1 is a MIDI-based controller board that works with the Classic Organ Works LRT-3A Lighted Rocker Tabs.
It is designed especially for use with organ consoles used to control Hauptwerk virtual organs via MIDI.
Up to eight full LRT-3A boards (128 stops) can be controlled.
Lamps on the LRT-3As are controlled by the MLRT-1 from MIDI data returned from the Hauptwerk's internal combination action.
The MLT-1 could be used with lighted drawknobs that push-on and pull-off. However, the lamps require a separate lamp-driving board.
The two MIDI-Through connectors allow other MIDI-driven devices to be used in order to reduce cabling. These outputs are simply duplicates of the MIDI-In signal.
The MLRT-1 may be mounted by either clips or screws and does not require any special cooling.
