is there a way to create a MIDI note probability gate? i.e. take an incoming MIDI note, and allow it pass through based on the user-defined probability of doing so

so if set to "0.10". there is a 10% chance the note will pass through, and at "1.0" a 100% chance...

Hi !
this is the easy way if you don't need the note off :

of course you can. here's an example:

just make sure to set Random module to only generate number on trigger. btw, notice that Random module also got random MIDI note output if you need it. this is for trig/gate situation. as for value randomisation, you can go farther than that, like setting a probability map for values (so your random values are more likely to land on specific spots). solving those problems helps getting better at math, because it's a fun way to solve math problems.

@x.iso I am attempting to replicate your patch but have encountered a couple small issues

Image

- I don't see any "trigger in" on my "Random" module

- I am not sure how to get "probability" on my fader for "Chng Scale"

EDIT: also not sure how to get my image file to display here!

about image, you've added additional '[' right after img tag, that makes tag invalid.

about Random, sorry, I've just checked and it turns out this option was added in HH4 beta, which I used for example. I'll make example patch for HH3 189 soon

EDIT: in HH3 Random module got 'generate' input as trigger, you just need to set synchro - button as well in it's settings.

you can use it as sub-patch in your patch if you want, or just between patches in rack.

Hi everyone,
sorry if this is a bit off topic, but this is my first post- I'll create a new topic as soon as I'm allowed to. Where in the manual do I have to look to figure out how to patch a simple midi switcher? Here's what I want to achieve: I've got a MIDI foot controller connected to my computer and it's controlling plugin A. I want to hit a MIDI note to re-direct the MIDI data of that controller to plugin B.
Sorry for such a noob question, I guess that's really easy to do, but I've watched the first 10-12 tutorial videos and I'm still not sure where to search for an answer...

Hello Holz&Strom and welcome,

Most of the flow's in Usine are compatibles, so you can use a simple data mix dispatcher module to route the MIDI in messages to 2 directions, directly or via MIDI buses if if needed
Add a switch to the select inlet (values 1-2) and create a MIDI learn on it
