Sequencer tracks and playing Combis When you create a Combinator device, a sequencer track is automatically created. This track is also given Master Keyboard Input just like standard instrument devices. When the Combinator track receives incoming MIDI data, this will be routed to all instrument devices in an instrument Combi. This means that the devices will be layered when you play (taking default velocity and key ranges into account). You can turn off Receive Note or selected Performance controller data for individual instrument devices in the Programmer panel. See “Using the Programmer” for details.
