Bela and SuperCollider Server localhost not running, could not send SynthDef.

Mila

Hey!
Hi to all, pleased to meet you!
I am kind of pretty new to Bela.

I am trying to run a SC on Bela, but I have some problems about it!
Right now it tells me that:

WARNING: Server localhost not running, could not send SynthDef.

There is the code if you want to have a look and hopefully give me some feedback!

s = Server.default;

s.options.numAnalogInChannels = 2; // can only be 2, 4 or 8
s.options.numAnalogOutChannels = 2;
s.options.numDigitalChannels = 0;
s.options.maxLogins = 4; // set max number of clients
s.options.bindAddress = "0.0.0.0"; // allow anyone on the network connect to this server

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

s.options.postln;

b = Buffer.read(s,"/root/Bela/projects/Start3/MitWMitL.wav");
q = Buffer.read(s,"/root/Bela/projects/Start3/MitWOhneL.wav");
w = Buffer.read(s,"/root/Bela/projects/Start3/OhneWaMitL.wav");
w = Buffer.read(s,"/root/Bela/projects/Start3/WohneLohne3.wav");

(
SystemClock.sched(2.0,{ //um zu Demonstration nur 2 Sekunden
"2.0 seconds later".postln;

//Mit Wasser mit Licht
(~a = 0;
~z = if (~a >4,(
SystemClock.sched(2.0,{
"2.0 seconds later".postln;
(SynthDef(\help_PlayBuf, {| out = 0, bufnum = 0 |
Out.ar(out,
PlayBuf.ar(1, bufnum, BufRateScale.kr(bufnum), doneAction: Done.freeSelf)
)
}).play(s, [\out, 0, \bufnum, b]) ; );}; ); ); ); );

//Mit Wasser Ohne Licht
(~a = 1;
~x = if (~a > 3, (
SystemClock.sched(2.0,{
"2.0 seconds later".postln;
(SynthDef(\help_PlayBuf, {| out = 0, bufnum = 0 |
Out.ar(out,
PlayBuf.ar(1, bufnum, BufRateScale.kr(bufnum), doneAction: Done.freeSelf)
)
}).play(s, [\out, 0, \bufnum, q]); );}; );
); ); );

//Ohne Wasser Mit Licht
(~a = 1;
~c = if (~a > 0, (
SystemClock.sched(2.0,{
"2.0 seconds later".postln;
(SynthDef(\help_PlayBuf, {| out = 0, bufnum = 0 |
Out.ar(out,
PlayBuf.ar(1, bufnum, BufRateScale.kr(bufnum), doneAction: Done.freeSelf)
)
}).play(s, [\out, 0, \bufnum, w]); );}; );
); ); );

//Ohne Wasser Ohne Licht
(~a = 1;
~c = if (~a > 5, (
SystemClock.sched(2.0,{
"2.0 seconds later".postln;
(SynthDef(\help_PlayBuf, {| out = 0, bufnum = 0 |
Out.ar(out,
PlayBuf.ar(1, bufnum, BufRateScale.kr(bufnum), doneAction: Done.freeSelf)
)
}).play(s, [\out, 0, \bufnum, e]); );}; );
); ); );

}; ); )

Thanks in advance!

s = Server.default; is not enough to boot the server. It just tells sclang where to find the server, but you need something like s.boot or s.waitForBoot() to start it up - unless you start it separately (e.g.: via a script). waitForBoot() is the pattern used in most of our examples. See a simple example here (or on the board under examples/SuperCollider/0-hello-sc)

In your case, adding s.waitForBoot() around the relevant code should work. E.g.:

s = Server.default;

s.options.numAnalogInChannels = 2; // can only be 2, 4 or 8
s.options.numAnalogOutChannels = 2;
s.options.numDigitalChannels = 0;
s.options.maxLogins = 4;  	   // set max number of clients
s.options.bindAddress = "0.0.0.0"; // allow anyone on the network connect to this server

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

s.options.postln;


b = Buffer.read(s,"/root/Bela/projects/Start3/MitWMitL.wav");
q = Buffer.read(s,"/root/Bela/projects/Start3/MitWOhneL.wav");
w = Buffer.read(s,"/root/Bela/projects/Start3/OhneWaMitL.wav");
w = Buffer.read(s,"/root/Bela/projects/Start3/WohneLohne3.wav");


s.waitForBoot(){
	(
SystemClock.sched(2.0,{ //um zu Demonstration nur 2 Sekunden
	"2.0 seconds later".postln;

//Mit Wasser mit Licht
(~a = 0;
~z = if (~a >4,(
SystemClock.sched(2.0,{
    "2.0 seconds later".postln;
(SynthDef(\help_PlayBuf, {| out = 0, bufnum = 0 |
    Out.ar(out,
        PlayBuf.ar(1, bufnum, BufRateScale.kr(bufnum), doneAction: Done.freeSelf)
    )
	}).play(s, [\out, 0, \bufnum, b]););};););););

//Mit Wasser Ohne Licht
(~a = 1;
~x = if (~a > 3, (
SystemClock.sched(2.0,{
    "2.0 seconds later".postln;
(SynthDef(\help_PlayBuf, {| out = 0, bufnum = 0 |
    Out.ar(out,
        PlayBuf.ar(1, bufnum, BufRateScale.kr(bufnum), doneAction: Done.freeSelf)
    )
	}).play(s, [\out, 0, \bufnum, q]););};);
	);););

//Ohne Wasser Mit Licht
(~a = 1;
~c = if (~a > 0, (
SystemClock.sched(2.0,{
    "2.0 seconds later".postln;
(SynthDef(\help_PlayBuf, {| out = 0, bufnum = 0 |
    Out.ar(out,
        PlayBuf.ar(1, bufnum, BufRateScale.kr(bufnum), doneAction: Done.freeSelf)
    )
	}).play(s, [\out, 0, \bufnum, w]););};);
	);););


//Ohne Wasser Ohne Licht
(~a = 1;
~c = if (~a > 5, (
SystemClock.sched(2.0,{
    "2.0 seconds later".postln;
(SynthDef(\help_PlayBuf, {| out = 0, bufnum = 0 |
    Out.ar(out,
        PlayBuf.ar(1, bufnum, BufRateScale.kr(bufnum), doneAction: Done.freeSelf)
    )
	}).play(s, [\out, 0, \bufnum, e]););};);
	);););

};);)
} // close waitForBoot

Many many thanks! Everything works correctly now! <3

also make sure you checkout the SuperCollider/7-remote-control example if you want to do quick prototyping by live-coding from the Supercollider IDE on the host.
