Arrays as arguments to SynthDef?

We’re all and always ! :slight_smile:
There’s no way to circumvent this, when wanting dynamic length array input you have to decide for a max size first in your synthdef. Then you’re free to pass smaller arrays and handle them appropriately. This appropriate handling can be done in different ways

(
~qp1 = [0,1,2,3];
~qp2 = [0,1,2,3,4,5];

SynthDef(\testArray_1, {
	arg size = 7, points = #[111, 222, 333, 444, 555, 666, 777];
	// indicator is a multichannel *UGen*
	var indicator = { |i| i < size } ! points.size;
	(indicator * points).poll; 
}).add;
)

// compare

z = Synth(\testArray_1, args: [\points, ~qp1]);

z = Synth(\testArray_1, args: [\points, ~qp1, \size, ~qp1.size]);


// alternatively - then 'size' and indicator in the synthdef isn't needed

z = Synth(\testArray_1, args: [\points, ~qp1.copy.extend(7, 0)]);

Of course it’s possible to fill/extend with numbers different from 0.

NamedControl doesn’t change anything about the fixed array size limitation, it only makes it easier to write large array args.
