Hi @CUSTOM_ROBO

I've managed to do this following [these instructions](https://tidalcycles.org/index.php/Controller_Input#MIDI)

I slightly edited the SC code to get it to do what I wanted:

And then using code in Tidal like this:

`d4 $ sound "arpy" # up (cF 1 "n")`

Depending on the pitch of your samples etc you will probably need to transform the midinote to a lower number, as `up` maps to semitones, rather than midinotes.

Something like:

`d4 $ sound "arpy" # up ((cF 1 "n")-60)`

And you might need to have a play around with noteon/noteoff (I used this in a kind of drone/noise setting so wasn't such a big deal for me, but this setup will still play the tidal pattern even when a note isn't being pressed - you could try mapping noteon/noteoff to `#gain` to help with this).

Hopefully this will get you started - shout back if you need any help.
