Some basic questions

AAAA) getUptime!
I was confused by the "seconds" word in the API, but it uses ms

d.healey

Yeah that confused me too :)

Levitanus

emmm.... The same problem with while loop. Even don't know who could expect)))
Well, it seems, the unique timer is the best solution at the moment)

Christoph Hart

A key difference to KSP is that there is no wait() instruction. Instead you delay events using Message.delayEvent(). The problem with stuck notes can be solved by delaying the note off command with the same amount (it's hardly noticeable on note off commands).

Don't use the Engine.createTimerObject() for audio stuff. This is running in the GUI thread and has absolutely no predictability or accuracy.
There are scripting callbacks for adding volume fades. Check out Synth.addVolumeFade().
the onTimer callback runs in the audio thread and has sample accuracy.

Thanks for the hint, I'll fix the getUptime doc in the API...

Levitanus

Ok, I think, the last question in this direction))
How about JUCE API? Can it work inside the script processor?

Levitanus

can't find are reg global, and if not, 32 per plugin or 32 per script?

Christoph Hart

32 per namespace:

namespace n1
{
    reg n1_1 = 1;
    // ...
    reg n1_32 = 32;
}

namespace n2
{
    reg n2_1 = 1;
    // ...
    reg n2_32 = 32;
}

Levitanus

Very interesting)))
So i can use 32 pieces of
reg atck_var
and 32 of
reg sus_var &

And they are global, am i right?

Another question. I placed Synth.noteOffByEventId(atck_id); into timer callback, as well as to the note_off callback. Now, pretty predictable i receive error in console about missing event by timer or by noteOff callback depends on situation. Is it bad? Or I can eat it as usefull information and newer mind?

and more, more questions ))))
When does envelope work? I know that once triggered by the voice KONTAKT envelope works as it was before triggering, even if it has been changed during the note playback.
For example, if I move some points in noteOn, will it "eat" them respectivelly to the current note and not for any other already triggered?
or it will work with all currentely produced samples? Or new values will be produced only with next notes, or with artifically played with a bit of delay?

P.S. and.. I have been confused a little by the dates od requests, so can;t understand actual things. Is timer global for the plugin, or local for each script?

Levitanus

Well I have almost done the "Hello world", but can't find how to set persistence of wigets... Or they will be saved automatically (as fbx)?

Christoph Hart

Widgets are persistent by default. If you don't want this, you can call

widget.set("saveInPreset", false);

Levitanus

Thanks! But I can't get the widget value by simple:

modwheel = Content.addKnob("modwheel", 346, 110);// [JSON modwheel]
Content.setPropertiesFromJSON("modwheel", {
  "max": 127,
  "stepSize": "1"
});
// [/JSON modwheel]
modwheel.showControl(false);
Globals.MW = modwheel.getValue();

What should be here else?

Christoph Hart

The persistent data is not available in the onInit callback. This happens behind the scenes:

The persistent widget values are stored.
The script gets compiled.
The persistent widget values are restored.
For all persistent widgets, the onControl callback gets executed.

In your case, you need to move the

Globals.MW = modwheel.getValue();

line in the onControl callback.

Levitanus

why Event is not been ignored?

reg note = 0;
reg vel = 0;

reg newnote = 0;
reg lastnote = 0;
var i = 0;
Globals.pos_interval = 0;
Globals.neg_interval;

Globals.Attack_length = 600;
Globals.Attack_fade = 150;
Globals.Release_fade = 200;

Globals.Attack = 0;
Globals.Legato = 0;
Globals.Glissando = 0;

function onNoteOn()
{
	if (lastnote == 0)
	{
		Globals.Attack = 1;
	} 
	if (lastnote != 0)
	{
		if (Message.getVelocity() < 80)
		{
			Globals.Legato = 1;
			interval = lastnote - Message.getNoteNumber();
			Globals.pos_interval = Message.getNoteNumber() - lastnote;
			Globals.neg_interval = lastnote - Message.getNoteNumber();
			if (Globals.pos_interval >0)
			{
				Message.setVelocity(Globals.pos_interval);
			}
			if (Globals.neg_interval >0)
			{
				Message.setVelocity(Globals.neg_interval);
			}
		} else
		{
			Globals.Glissando = 1;
			interval = lastnote - Message.getNoteNumber();
			Globals.pos_interval = Message.getNoteNumber() - lastnote;
			Globals.neg_interval = lastnote - Message.getNoteNumber();
			if (Globals.pos_interval >0)
			{
				Message.setVelocity(Globals.pos_interval);
			}
			if (Globals.neg_interval >0)
			{
				Message.setVelocity(Globals.neg_interval);
			}
		}
	}
	lastnote = Message.getNoteNumber();
}
function onNoteOff()
{
	Globals.Attack = 0;
	Globals.Leg = 0;
	Globals.Glissando = 0;
	if (Message.getNoteNumber() == lastnote)
	{
		lastnote = 0;
	}
}

//script perocessor 2
Sampler.enableRoundRobin(false);
reg leg_grp = 0;
reg vel = 0;
reg note= 0;

if (Globals.MW > 64)
{
	leg_grp = 1;
}else
{
	leg_grp = 2;
}
function onNoteOn()
{
	note = Message.getNoteNumber();
	vel = Message.getVelocity();
	Message.ignoreEvent(true);
	if (Globals.Glissando = 1)
	{
		Synth.playNote(note,vel);
	}
}

The problems are:
Globals.Legato and Globals.Glissando are set with every event.
And even with setting them to 0 leg and gliss samplers are played. But shouldn't because of ignoreEvent

d.healey

I might be too tired to be thinking striaght but I think you need to ignore the event in your first script too

Christoph Hart

Yes. Events have a natural signal flow so if it gets ignored in the second script, the first script is long gone waiting for the next event...

Levitanus

Well, in HISE all works pretty fine. Just couldn't add CC gain modulator to the master container.
But with compilled VST trash: https://www.dropbox.com/s/oa8xbrnxhqx0k7r/Hise Hello World by Levitanus.rar?dl=0

Problem A: engine settings button is visible and crushes the host.
Problem B: nothing is sounding, but voices are triggered.

Playable keys G3,A3,E4. And CC1

d.healey

CC Modulators can't be added to the master container but you can add them as a global modulator :)

Levitanus

but you can add them as a global modulator :)

wah! of course!

Levitanus

And what is with compiled VST? Where have I mistaken?

Christoph Hart

I'll need to take a look. The engine settings button is definetily a bug and if HISE makes sound but the compiled plugin doesnt then theres something wrong too.
