[sc-users] Can MixerChannel and PbindFX play nicely together?

[jimwhelan63@xxxxxxxxx]

Hi,

Does anyone successfully use PbindFx (miSCellaneous_lib) and
MixerChannel (ddw) together? I'm trying to use the MixerChannel to
record stems from some PbindFX-driven patches I'm working with.
Unfortunately, my test patch is throwing an error and I'm not sure how
to fix it. Both MixerChannel and PbindFx have differing naming
conventions for their SynthDef inputs and outputs. According to the
MixerChannel help, I think I've addressed this. Quoting:

-------------------------------------------------------
Note that if you use MixerChannel.play, you don't have to specify the
bus number as long as your synthdef uses outbus as the output bus
argument. Otherwise, do this:

a = m.play("pinkfilt", [\freq, 2000, \rq, 0.02, \out, m.inbus.index]);
-------------------------------------------------------

I'm using an outdated SC (v 3.6.6) on an old OSX (10.6.8). My PbindFx
is pretty recent, but my MixerChannel help has a "New feature (16 July
2005)", so it might be ancient. I'm unable to use the Quarks system to
update, so I'm hoping this is just me not understanding something.

Here's some test code:

// test FX SynthDef
(
SynthDef(\freeverb, { |out, in, damp(0.5), room(0.5), amp(1), mix(1)|
	var signal, rvb;
	signal = In.ar(in, 2);
	rvb = FreeVerb.ar(signal, mix, room, damp, amp);
	signal = signal + rvb;
	Out.ar(out, signal);
}).add;
)

// the mixer channel
m = MixerChannel("test1", s, 2, 2, 1);

(
// the sequence
p = PbindFx([
	\instrument, \default, // use default Synth for test
	\dur, 0.25,
	\amp, 0.2,
	\midinote, Pseq([60, 67, 70, 73], inf),
	\fxOrder, [1],
	\out, m.inbus.index, // not sure about this
	// \out, 0,
	\cleanupDelay, 0.1
	],[
		\fx, \freeverb,
		\amp, 1,
		\room, 0.9,
		\mix, 1,
		\cleanupDelay, Pkey(\room) * 9
	]
);

// play sequence through a mixer channel
x = m.play(
	p,
	[\out, m.inbus.index], // this, according to MixerChannel help
	(quant: 2.0)
);
)

This is the error I'm getting:

-------------------------------------------------------
ERROR: Primitive '_BasicAt' failed.

-------------------------------------------------------

Does anyone successfully use PbindFx and MixerChannel together? For
me, they're both very useful additions to SuperCollider, so it would
be unfortunate if they didn't play together.

Thanks very much (and sorry for the long post).
