I suggest a new midi fx, a note on random, it creates a random value for a CC, means each note would play a random modulation value. (Solved with Maartens answer ! Thank you.)
2nd suggestion: after x count notes, a set CC value is send to the synth. (last note in bar sends a CC to the synth to activate delay send fx, reverb etc) to extend the phrase, would save a lot of automation work.
The suggestion is essentially building on the random “lot” effect - its adding a capability to the pass x amount of notes - i.e. send a CC value before and with the last note of the passed group of notes.) The random fx is already there, it should only allow to set a additional CC value pair before and on the last note of the the passed notes.
Conditional values for automations would also be welcome, i.e. randomize which automation bar would be played, or not played. Or a stretch/double time for automation data…
