How to make a Panic Button (Send All MIDI Off)?

[Lindon]

@WillDevelop just send 128 note off messages?

[WillDevelop]

@Lindon can you give me an example code how I can send this via a button click?

[Lindon]

@WillDevelop

do you know how to generate a midi note off message?

[d.healey]

@Lindon Ah such a simple idea!

thats me - full of simple ideas.....

@Lindon Not really, only in conjunction with a Note On command

@Lindon Not really, only in conjunction with a Note On command

so look in the documentation for NoteOff

eventually` you will find:

Synth.noteOff(int noteNumber)

so ...

for(i=0; i<128;i++)
{
   Synth.noteOff(i);
}

[WillDevelop]

@Lindon
But does it also send a Note Off command to another plugin?
Because the plugin does not generate its own sounds, but only outputs MIDI data.

[Lindon]

@WillDevelop really, just type it in and try it.. if not - then you have learned something.

[WillDevelop]

@Lindon Okay, I tried it and it didn't work.

[WillDevelop]

I have found a solution

Button Callback

if(isMidiPanicBtnActive == 0)
{
   isMidiPanicBtnActive = button.getValue;
   button.setValue(0);
}

onNoteOff Callback

if (isMidiPanicBtnActive == 1)
{

	for(i=0; i<128; i++)
	{
		Message.setNoteNumber(i);
		Message.sendToMidiOut();
	}

	isMidiPanicBtnActive = 0;
}

The only downside of this solution is that you have to press the button and then press a midi key
Because I don't think it is possible to send a message command with a button click, at least not "Message.setNoteNumber()"

I know you guys are always looking at the “coding” way to do this…but wouldn’t a simple “no code” way to do this be to just create a button…make it momentary and assign it to the project master bypass? Because doesn’t that send an “All notes off” message that kills any midi/audio playing?

[WillDevelop]

@johnmike that would be a much simpler solution, but I found nothing in the documentation about project master bypass.

[d.healey]

That would just bypass your plugin, it wouldn't send MIDI out.

[Christoph Hart]

The proper solution would be adding a sendToMidiOut() to the MessageHolder API object, then you can call this from anywhere. But it's a sensible request, I just didn't use the MIDI out functionality myself too much in order to need it.

[d.healey]

@Christoph-Hart Would it be possible to add a more generic midi out that allows to send artificial events too?

[Christoph Hart]

@d-healey sure, the idea would be that you can send any message type like this.

[johnmike]

Gotcha...def the scripting stuff for sending midi out to other plugins...but as far as just creating a generic "Panic" button this is what I was talking about...just for the guys and gals that are trying to accomplish a simple task of creating a simple "Panic" button...WARNING turn speakers down for the audio example...

sendToMidiOut

That's a good suggestion, but when trying around with the MessageHolder object I noticed that the object does not have the function sendToMidiOut() at all and if I understand correctly sendToMidiOut() only works in the Midi callbacks, which is only triggered when a Midi signal comes in

[d.healey]

@WillDevelop Christoph is saying he needs to add this functionality to HISE, it isn't there yet
