Browsable Snippet: [Clocksynced Arpeggiator]

M_Holloway

@Christoph-Hart I have a project that currently uses three samplers, each with its own arp. I stumbled across this yesterday and was initially excited because of the improved sync but then spotted this:

// The only real limitation of this approach is that it doesn't allow multiple arpeggiators to run
// simultaneously (because there's only one grid callback) but that is a rather exotic use case

As an experiment, I made a project with three waveform generators and added a script processor to each to run this code in and, following a bit of tweaking, observed that everything could be set individually with the exception of the Tempo value. Tempo value was global and reflected whichever of the three Tempo controls was last moved.

Is the reason you can only have one Tempo value because you can only have one transport handler? Is there any possible way to enable all parameters to be set on a per instance basis?

Found one solution to this question:

Regarding the octave range, is it possible to make it go negative?

First, customize the min, max and middlePosition for the octave knob properties:

 // The number of octaves. This will create octaved copies of the currently held notes
 const var numOctaves = Content.addKnob("Octaves", X_OFFSET + 0, Y_OFFSET + 60);
 numOctaves.set("min", -4);
 numOctaves.set("max", 4);
 numOctaves.set("middlePosition", 0);
 numOctaves.set("stepSize", 1);

Then make changes to the rebuildSortedList function to:
Calculate absolute value of the octave range knob.
Add if statement to discern upwards from downwards transposition.

 
 inline function rebuildSortedList()
 {
 	// Clear the sorted list
 	sortedList.clearQuick();
 
 	// Sort the notes before stacking them up in the octaves
 	activeNotes.sort();
 
 	// for each octave, insert the sorted list into the note array
 	for(i = 0 ; i < Math.abs(numOctaves.getValue()) + 1; i++)
 	{	
		for(s in activeNotes)
 		{
 			// Copy all relevant properties (currently we don't)
 			// use the velocity property at all, but that can be
 			// used for further customization
 			if (numOctaves.getValue() >= 0) scratch.noteNumber = s.noteNumber + i * 12;
 			else scratch.noteNumber = s.noteNumber + i * -12;
 			scratch.id = s.id;
 			scratch.velocity = s.velocity;
 			sortedList.insert(scratch);
 		}
	}
 };

I think you can have several arps running in different tempos with Christophs "Clocksynced Arpeggiator" if you have them set per/voice source.
I haven't tried this but I managed to do it in this experiment where I built an arp using the Transport Handlers setEnableGrid() function

Take a look in the snippet and maybe you can find a way to do it in your project
Remember this is only a test and I know nothing about the performance or any complications that can come from it, but so far so good.

@ulrik Thanks for this, definitely a pointer in the right direction. I'll have a proper play around with it tomorrow :)

Orvillain

Heya!

I modified the clocksynced arpeggiator example slightly for my own needs.

But I am wondering - what advantage does it have over just using the Arpeggiator midi processor???

DanH

@Orvillain I couldn't get this working nicely - the sliderpacks would never recall the settings properly. Does it work ok your end?

I'm not using slider packs. I'm using custom drawn script panels, and I save the step data into the panel value field for preset store/recall.

I don't really like slider packs, and I try to avoid them at all costs. Coz they're ugly and mean.

DanH

@Orvillain Yes I agree.

HISEnberg

@Orvillain Indeed, as far as UI components go the sliderpack is a bit of an ugly duck. It's much nicer with the new CSS facelift:

https://docs.hise.dev/ui-components/plugin-components/sliderpack.html

Just curious do you have an example of a using a panel to control an arpeggiator?

I'll have to put one together, because the one I have is the clients.

But basically I did a piano roll kind of interface, where I can specify pitch and length, in a grid. Then an extra velocity lane below. I draw a grid according to the steps count, centre lane across the middle, +12 and -12 range below. So it's a load of squares in a grid. Each cell can be clicked on and off, and when you click it off, you can drag the right-most edge to change the size of the note.

It's all pretty straight forward graphics context drawing to be honest; tied in with Christoph's arp snippet.
