I want to take a preset MIDI instrument and make it ignore every inputted note besides "A." The transposer MIDI effect unfortunately does not do what I want because even if I hit notes that aren't "A," it will still send an "A" to the instrument. I don't want this. Thanks. I'm using version 10.4.1
Okay, I figured it out. If anyone's interested, I was able to achieve what I wanted by modifying the script for the Scripter MIDI effect preset "Key Range" and saving it as a new preset. The modified script looks like this:
var activeNotes = [];
function HandleMIDI(event)
{
if (event instanceof NoteOn) {
if (event.pitch % 12 != GetParameter('Pitch') % 12)
return undefined;
else {
activeNotes.push(event);
event.send()
}
}
else if (event instanceof NoteOff) {
for (i=0; i < activeNotes.length; i++) {
if (event.pitch == activeNotes[i].pitch) {
event.send();
activeNotes.splice(i,1);
break;
}
}
}
else { // pass non-note events through
event.send();
}
}
var PluginParameters = [
{ name:'Pitch', type:'lin',
minValue:0, maxValue:127, numberOfSteps:127, defaultValue:115},
];

Sorry, I wasn't very clear. What I actually want is to be able to play ANY "A" notes (of any octave) but have the instrument ignore all the other notes I play. What you mentioned here is a good feature I didn't know about, but unfortunately, it can't do what I want.
Use the "key limit" parameter in the track inspector.
I should have mentioned: I specifically want to be able to play every octave of "A," (so A1, A2, A3, etc.) while all other notes I play are completely ignored.
How can I filter out certain midi notes from entering an instrument?
