mode switches detected on the audio thread!

sps should i say yes to it to continue?

Yes. That just means that it's the first time you connect to the board.

This is what happened after "yes". But the problem (mode switch detected on the audio thread) still shows up after i get back to my code:

s = Server.default;

s.options.numAnalogInChannels = 8;
s.options.numAnalogOutChannels = 8;
s.options.numDigitalChannels = 16;

s.options.blockSize = 16;
s.options.numInputBusChannels = 2;
s.options.numOutputBusChannels = 2;

s.options.postln;

s.waitForBoot({
"Server Booted".postln;

SynthDef(\pressSensorL, {arg inbus = 0, outbus = 0;
var toe, heel, signal;
toe = AnalogIn.ar(0);
heel = AnalogIn.ar(1);
signal = toe * heel;
Out.kr(outbus, signal);
}).add;

SynthDef(\pressSensorR, {arg inbus = 0, outbus = 0;
var toe, heel, signal;
toe = AnalogIn.ar(0);
heel = AnalogIn.ar(1);
signal = toe * heel;
Out.kr(outbus, signal);
}).add;

//System Specifications
~variableMappingRate = 0.01;

// create Buses
~leftBus = Bus.control(s, 1);
~rightBus = Bus.control(s, 1);

// create Variable
~leftVar = 0;
~rightVar = 0;

// Which Bus should be
l = Synth(\pressSensorL, [\outbus, ~leftBus] );
r = Synth(\pressSensorR, [\outbus, ~rightBus]);

Tdef(\VariableSwitch, {
loop{
~leftBus.get({arg value; ~leftVar = value;});
~rightBus.get({arg value; ~rightVar = value;});
~variableMappingRate.wait;
}
}).play;

SynthDef('pm', {arg freq=200, amp=0.5, pan=0, dur=1, modfreq=200, idx=0.1, modphase=0, trig=1;
var sig, env;
sig = PMOsc.ar(freq, modfreq, idx, SinOsc.ar(modfreq 3));
env = EnvGen.ar(Env.perc(0.01, 1), trig, timeScale: dur, doneAction: 2);
Out.ar(0, Pan2.ar(sig env * amp, pan));
}).add;

Tdef(\Test_The_VariableSwitch, {
~synthPm = Synth(\pm, [\out, 1]);
loop {
~synthPm.set(\freq, ~leftVar);
~synthPm.set(\dur, ~leftVar);
~synthPm.set(\amp, ~rightVar);
}});

Tdef(\Test_The_VariableSwitch).play;
})

Do you have any ideas what the problem could be?
Best,

An Error shows up:
error: cannot access archive 'Supercollider-v3.11.2-bela.debssh': No such file or directory

could you run the commands exactly as I wrote them in the previous post?

giuliomoro Right you have some errors in the code you ran so far ( the trailing d).

Could you point out what you mean by the trailing d?

sps it shows no such file or directory

did you download the file I linked to to your desktop? If you download it to some other location you will need to adjust the path in the command accordingly, which is why I recommend you download it to the Desktop.

yes, I am sorry for misunderstood. And no error message has printed on terminal.
Back to Bela IDE, and got a new error:

although it does not shows any error. But i couldn't even run the SuperCollider Example Code on Bela IDE after it...
Any ideas how could i fix it?
Thanks

giuliomoro thanks alot! It works out!!

Great, sorry it took a while
