MIDI controlled Step Sequencer



I am in need of a sequencer that would be triggered by a MIDI note “On” and keep running the sequence until note “Off”. A note “On” message would always reset the sequencer to step 1.

Also, the sequenced notes would be transposed according to the triggering note.

I am currently using an app called " Arpeggist" in my iPad to do this but having a plugin in the Mod Duo would illiminate the need for the iPad.

X42 Plugins are almost there but do not take a MIDI note as an input to trigger the sequence.


There is at least one sequencer in the duo that has an assignable start/stop
I just loaded a pedalboard that used it


Can you give me the name of that sequencer or the name of the pedalboard?
