Hi!
I am not sure if the problem is regarding the VSTPlugins, the plugin itself (ambisonics 7th order with 64 channels) or some sort of client-server timming, but when I try to set many parameters of the VSTPluginController I am getting lots of error messages ERROR: non bolean in test. This is the code that I am using:
//Windows - SC 3.13.0
//vstplugin v0.5.4
~percussionSample = Buffer.read(s,"path/to/some/sample/percussionSample.wav");
~outOffset = 4 ; // interface bus offset
~numLoudspeakers = 25;
(
s.waitForBoot({
Server.freeAll;
s.newBusAllocators;
s.boot;
s.sync;
// SynthDefs
~order = 7; // set this to the order you want
~numChannels = ((~order + 1)**2).asInteger;
// 1 - Sound Source (Stereo)
SynthDef(\sampler, { | out = 0, vol = 1.0, buf=0 |
var sig;
Out.ar(out, PlayBuf.ar(2, buf, BufRateScale.kr(buf),loop: 1.0, doneAction: Done.freeSelf)* vol);
}).add;
// 2 - directivity shaper encoder (mono -> ~numChannels) - coverts a mono signal into a ambisonics ~numChannels signal
SynthDef.new(\directivityEncoder, { | bus = 0 |
ReplaceOut.ar(bus, VSTPlugin.ar(In.ar(bus, 2), ~numChannels));
}).add;
// 3 - helper Synth (throws audio from ambi bus to ambi master bus)
SynthDef.new(\ambiThrow, { | from, to |
Out.ar(to, In.ar(from, ~numChannels));
}).add;
// 4 - all round decoder (~numChannels -> ~numLoudspeakers) - reads from 'bus' and sums into 'out'
SynthDef.new(\allraDecoder, { | bus, out = 0 |
Out.ar(out, VSTPlugin.ar(In.ar(bus, ~numChannels),~numLoudspeakers));
}).add;
// Paralel Bus AmbiFX- ambisonics insert FX (replaces input with output)
SynthDef.new(\ambiFX, { | bus = 0, bypass |
ReplaceOut.ar(bus, VSTPlugin.ar(In.ar(bus, 2), ~numChannels, bypass));
}).add;
s.sync;
// create ambisonic master section
// bus + group
~ambiMasterBus = Bus.audio(s, ~numChannels);
~ambiMasterGroup = Group.new;
// binaural decoder (writes to master output)
~decoder = VSTPluginController(Synth(\allraDecoder, [\bus, ~ambiMasterBus, \out, ~outOffset], // INTERFACE CHANGE!!!!
target: ~ambiMasterGroup, addAction: \addToTail)).open("AllRADecoder");
// a group for ambisonic master effects
~ambiMasterFXGroup = Group.before(~decoder.synth);
s.sync;
// load decoder preset
~decoder.readProgram("some/path/to/your/preset/preset-decoder.fxp");
s.sync;
// create ambisonic busses
//add ambi groups *before* master group!
~numBus = 1;
~ambiBus = Array.newClear(~numBus);
~ambiGroup = Array.newClear(~numBus);
~encoder = Array.newClear(~numBus);
~numBus.do { |i|
~ambiBus[i] = Bus.audio(s, ~numChannels);
~ambiGroup[i] = Group.before(~ambiMasterGroup);
// sound source (head)
Synth.new(\sampler, [\out, ~ambiBus[i], \vol, 0.03 / ~numBus, \buf, ~percussionSample], ~ambiGroup[i], addAction: \addToHead);
// encoder (after sound source)
~encoder[i] = VSTPluginController(Synth(\directivityEncoder, [\bus, ~ambiBus[i]],
target: ~ambiGroup[i], addAction: \addToTail));
// open plugin and randomize azimuth
~encoder[i].open("DirectivityShaper", action: { |self|
"encoder loaded".postln;
self.set(11, rand(7.0));
self.set(12, 0.5);
self.set(19, rand(7.0));
self.set(20, 0.5);
self.set(27, rand(7.0));
self.set(28, 0.5);
self.set(35, rand(7.0));
self.set(36, 0.5);
});
// throw to master section (after encoder)
Synth(\ambiThrow, [\from, ~ambiBus[i], \to, ~ambiMasterBus], target: ~ambiGroup[i], addAction: \addToTail);
};
s.sync;
// move around with the VST editor:
~encoder.do(_.editor);
~encoder.do(_.gui);
//configure the decoder
//~decoder.do(_.editor);
s.sync;
})
)
and here is the error message:

^^ The preceding error dump is for ERROR: Non Boolean in test.

I’ve also tried to set the parameters in other parts of the code instead of doing it at the VSTPluginController.open() initialization, for example, after the penultimate s.sync with ~encoder.do(_.set(11, 0.0)) but I still get the same error.
Any ideas how to solve this?
Thanks a lot!
