midi plugin - deactivate certain midi notes

[apricotandpearjam]

hi all. 

i know there is a key range in the inspector for each midi track but id like to know if there was a way of choosing which notes you allow through and which you don’t. 

for example i might need C-2 > G-3 but also B-4 > G-5. 

this is to prevent me from hitting notes which change certain things like keyswitches or custom settings which certain libraries have laid out on keys. 

thanks!

This is something you could script in Scripter: 

function HandleMIDI(event) {
	if(event instanceof NoteOn) {
        if (event.pitch >= 36 && event.pitch <= 51 || event.pitch >= 65 && event.pitch <= 98) {
            event.send();
        }
    } else event.send();
}

Ok here's a better version, along with an interface to dial in the min/max for both pitch ranges! 🙂 

function HandleMIDI(event) {
	if(event instanceof NoteOn) {
        if (event.pitch >= GetParameter('Range 1 Min Pitch') && event.pitch <= GetParameter('Range 1 Max Pitch') || event.pitch >= GetParameter('Range 2 Min Pitch') && event.pitch <= GetParameter('Range 2 Max Pitch')) {
            event.send();
        }
    } else event.send();
    event.trace();

}

var PluginParameters = [
	{	name:"Pitch Range 1",
		type:"text"},
	{	name:'Range 1 Min Pitch', type:'lin',
		minValue:0, maxValue:127, numberOfSteps:127, defaultValue:30},
	{	name:'Range 1 Max Pitch', type:'lin', 
		minValue:0, maxValue:127, numberOfSteps:127, defaultValue:45},
	{	name:"Pitch Range 2",
		type:"text"},
	{	name:'Range 2 Min Pitch', type:'lin',
		minValue:0, maxValue:127, numberOfSteps:127, defaultValue:68},
	{	name:'Range 2 Max Pitch', type:'lin', 
		minValue:0, maxValue:127, numberOfSteps:127, defaultValue:88}
];

thankyou so much for this.

its incredibly helpful.

is there any way of editing this so that the pitch is displayed as midi notes ie G2 / B#3 etc rather than a number?

cheers 🙂

cant seem to get it working.

for some reason when i set the two key ranges its allowing some through that should get through and stops some that should come through.

have a look at this screen recording:

Yes! Here you go: 

var NOTES = MIDI._noteNames;				//array of MIDI note names for menu items

function HandleMIDI(event) {
	if(event instanceof NoteOn) {
        if (event.pitch >= GetParameter('Range 1 Min Pitch') && event.pitch <= GetParameter('Range 1 Max Pitch') || event.pitch >= GetParameter('Range 2 Min Pitch') && event.pitch <= GetParameter('Range 2 Max Pitch')) {
            event.send();
        }
    } else event.send();
    event.trace();

}

var PluginParameters = [
	{	name:"Pitch Range 1",
		type:"text"},
	{	name:'Range 1 Min Pitch', 
		type:'menu',
		valueStrings:NOTES,
		minValue:0, 
		maxValue:127, 
		numberOfSteps:127, 
		defaultValue:40},
	{	name:'Range 1 Max Pitch',
		type:'menu', 
		valueStrings:NOTES,
		minValue:0, 
		maxValue:127, 
		numberOfSteps:127, 
		defaultValue:45},
	{	name:"Pitch Range 2",
		type:"text"},
	{	name:'Range 2 Min Pitch',
		type:'menu',
		valueStrings:NOTES,
		minValue:0,
		maxValue:127, 
		numberOfSteps:127, 
		defaultValue:68},
	{	name:'Range 2 Max Pitch',
		type:'menu',
		valueStrings:NOTES,
		minValue:0,
		maxValue:127,
		numberOfSteps:127,
		defaultValue:88}
];

Seems to work as expected here? Try the new one and let me know. 

[David Nahmani]

@apricotandpearjam Did you get a chance to try my new script? It should work, and you now see note names: 

Let me know... and I'll move this thread to the Scripter forum later. 🙂

FWIW script works perfectly here. Attaching a Logic project that incorporates it.

this is absolutely amazing thankyou @David Nahmani.

the only improvement i would ask for is 3 pitch ranges and the ability to switch them on and off.

but other than that it works brilliantly.

Come on, you know how to do copy and paste don't you 😉 ?

jk I know it's not that simple, so here's the three range version.

Fair enough!

Version with switches:

Seems I copy & pasted a bit too quickly, here's a cleaner version

Thanks @polanoid for expanding on this script! Much appreciated. I'm moving this thread to the Scripter forum so we know where to find it. 🙂

You're welcome!
