Incremental midi note value out

You can add button step 127,

then use self:button_value() in the MIDI block Parameter1. To send the note’s full value, set Parameter2 to 127.

Crazy way to do it, but thanks

Here's an alternative approach... Set a self:note variable in the Setup and then increment it on each button press. You can set your starting point by whatever value you assign to the self:note variable. I also added a check so it loops back to 0 once it reaches 127.

self.note = self.note + 1
if self.note > 127 then
    self.note = 0
end

This will never turn the notes off, keep that in mind.

Yeah i thought about that too

perhaps unles I used button:state, instead of 127 in parameter 2

Yes it was just an example to start with, I don’t know your exact usecase:)

The world of MIDI is still a bit foreign to me but out of curiosity, how would you approach sending the note off command? Would you put it in the Release block? I guess that's also where you'd increment the note number...

Well of course, it would depend on the use-case.

Your solution is good, just use -1 for param2 in the midi block and simplify the code part with a modulus.
You also shouldn't use the Press/Release to have the button trigger on both ways to actually release the notes.

Thanks for the tips! 🙂

It would look like this (just got to a PC to make an image to illustrate what I mean).

(Even I messed it up.)

It's actually quite tricky, because the button would run its event twice, so it would count up twice if you just used it without press/release.

Ah yes, there are quite a few traps in this seemingly simple setup!
Even the modulus operator is tricky with having to use 128 instead of 127 so you can hit all the values. Sometimes I prefer to use more verbose code because it reduces the cognitive load. However, in the character limited environment of the Grid, I see why you used it!

Thanks for taking the time to illustrate it and point out these subtle details, it helps us learn!
