thanx

Scripting is your friend

davepine · February 24, 2019, 4:33pm

i’ll never know how to do that, sorry

davepine · February 24, 2019, 4:34pm

i found something that should work, but it doesn’t

pianopaul · February 24, 2019, 4:46pm

What do you want exactly, maybe I can write a piece of Code.

i have a footswitch that sends midi notes momentary on/off, i want to send G9 midi note on/off, and reassign that in the computer to send G9 off= cc 21 000 G9 on= cc 21 127

@pianopaul is right GP script is you friend, and what a friend

Create a MIDI in block in the back view
right mouse click on it => Osc/GPscript Handle => Set handle, then give MIDIin as a handle name
go to Window (in menu bar) => Show script editor

copy and paste the following script in the editor and compile:

Var
 MIDIin   : MidiInBlock

On NoteEvent(msg : NoteMessage) Matching G9 from MIDIin
  If msg.IsNoteOn()
  Then
    MIDIin.SendNow(MakeControlChangeMessage(21,127));
  Else
    MIDIin.SendNow(MakeControlChangeMessage(21,0));
  End
End

That’s it, be happy

i cant get past step one, i don’t know what you mean by create a midi block in the background…

cant i just open the script editor?

davepine · February 27, 2019, 12:23am

actually got pretty far but when i hit compile…

Syntax Error: Line 7, Col 35: Unexpected or unrecognised token
‘Matching’
missing From at ‘Matching’

and now i cant seem to paste that script in at all anymore, even after i quit and shutdown without saving anything

Take it slowly and most positively follow the pics…

This name is MIDIin has you can see in the script.
Then compile (The error you got is this missing handle name)

Try again with this help…

@davepine
Don’t forget to select “Use in GPScript”

davepine · February 27, 2019, 4:56am

did it again, exact same error message, i’m on gp ver 2.0.18 if that makes a difference

davepine · February 27, 2019, 5:06am

yes i named it
yes, i also tried checking the box “use gp script”

keyman · February 27, 2019, 11:07am

Change the MIDI Note number to G8

If you open Mldi Monitor and press the pedal what do you get?

David-san · February 27, 2019, 2:02pm

I cannot tell you if GP 2.0.18 had the Matching option for the MIDI block callback, but if it was not the case you can do it like this:

Var
  MIDIin   : MidiInBlock

On NoteEvent(msg : NoteMessage) from MIDIin

  If GetNoteNumber(msg)==127
  Then
    If msg.IsNoteOn()
    Then
        MIDIin.SendNow(MakeControlChangeMessage(21,127));
    Else
        MIDIin.SendNow(MakeControlChangeMessage(21,0));
    End
  Else
    MIDIin.SendNow(msg);
  End
End

Concerning the G9 “issue” raised by @keyman, I didn’t check at the time I wrote the first script, but I supposed G9 was thought to be the highest possible MIDI note. So I replaced G9 by 127. Please, following the differents steps adviced by @keyman, check if it works this way.

And of course, think of updating to GP 3, which is probably the best advice I can give to you.

davepine · February 27, 2019, 2:17pm

tried again, made sure midi notes were correct, tried different ones, still no luck and same error message

pianopaul · February 27, 2019, 2:34pm

Can you upload screenshots of the script window showing the error
and the complete code?

davepine · February 27, 2019, 2:37pm

davepine · February 27, 2019, 2:38pm
