Plexum by Sevenfifteen
Plexum mixes the best properties of an arpeggiator and a multitrack sequencer by allowing you to trigger up to five independent parallel sequences. Each sequence loops over one bar in the host’s tempo, but it starts when the assigned MIDI note starts and loops as long as it is held.
MIDI Note management is exactly as would be with an arpeggiator. First incoming note routes to the first sequence module, second note to the second, and so on. And just like an arpeggiator, notes that you release will force a re-assignment.
Example: Incoming notes C3, E3, G3:
- C3 plays in the first sequence
- E3 in the second
- G3 in the third.
- E3 is released.
- Now G3 plays in the second sequence.
Each sequence module’s steps can be freely set between 1 and 32. This allows for polyrhythms. Each step of each sequence has independent settings for MIDI channel, velocity and gate length parameters.
Everything can be tweaked at runtime, allowing experimentation.
Usage:
- Left click on a step to switch a step on or off.
- Right click on a step to switch parameter editing on or off.
- Left click and hold on a control to change value.
