Re: [sc-users] array dynamically in synthdef

["Andrew C. Smith" <acsmith@xxxxxxxxxxxxxx>]

I think that you can't pass arrays as arguments.  Anyway, here's an
idea for you:

(
SynthDef('dynKlanklac', {

| base = 30, num = 30 |

var freqs = (Array.fill(n, { (base + num.rand).midicps})), // Look at
the variable controls on this line
amps = (Array.fill(n, { 0.06 + 0.007.rand })),
ringtimes = (Array.fill(n, { 1.75 + 10.rand }));

	Out.ar(0,
		DynKlank.ar(`[freqs, amps, ringtimes], WhiteNoise.ar(0.01)))
}).load(s)
)

x = Synth('dynKlanklac');
x.setn(\num, 35, \base, 27);

So this way you can change the parameters without actually passing a
new array.  In order to get stranger (non-tuned) filters, you should
really move away from midicps and go toward a floating-point
exponential system.  It'll get much better detuned results.  Any other
ideas?
