TM-1 Trigger Multiplexer allows you to connect multi-gate rack sequencers like Redrum, Propulsion, Euclid, Elementary and more, to instruments that only have the standard Gate and Note CV input pair. This opens up a whole new palette of drum instruments and sounds to use: NN-XT, Combinators and VSTs.

Product details

Using a technology called multiplexing, TM-1 converts 16 separate gate CV signals into the standard Gate and Note CV pair used by most instruments in Reason. It comes packed with pre-routed Combinator patches for all popular rack sequencers, and a variety of key mapping patches. All ready to use your rack sequencer with drum sounds from NN-XT, Combinator or VSTs!

Each channel has a name label, a note setting, and mute/solo buttons. There is a MIDI learn mode for the note setting, and it can even be automated and Remote-controlled. An Audition feature sends triggers when the note setting is changed, making it easy to find the right note. The mute and solo states are stored in the patch, which opens up creative possibilities for live use.

Besides its main functionality, TM-1 can also be used to write rack sequencer patterns into Note Clips in Reason’s sequencer. There is info on how to do this in the TM-1 User Guide, and in one of our Quick Tip videos.
