Just having a look @LandscapeSetting
One thing I started to wonder about with the previous patches - that also applies to this one:
how do they know where to send the Note_Off? Or does this not matter with the device you’re sending to?
Looking back up the thread I see I mentioned Note_Off issue before.
If it is an issue, how about using your LFO(s) to do your random switching directly within the Dispatcher itself? (this might be an avenue already rejected)
For this you’d probably adopt a sample and hold strategy using ideas like those mentioned by @Brachland and @sdk75 last year here.
