they can help save you time from having to build them from scratch,
and they also take away the guesswork of where the Matrix curve should be to trigger the desired pattern...
Here are some patches I put together for all my players with patterns.
Simply program the Matrix to play the pattern order you want (like a sequencer).
Robotic Bean Step Note Recorder
Robotic Bean Select CV Switch (not a player, but has an 8-way switch)
Robotic Bean Sequences
Lectric Panda Kompulsion
Lectric Panda Evolution
Reason Studios Drum Sequencer
Reason Studios PolyStep
