I try to send FFT data using OSC.

getnSynchronous dosenot work .

Is there Alternative way,method,function?

```
var fftArray= ~kbus.getnSynchronous(~buffersize2_fft);
~oscOut.sendMsg("/fftArray", *fftArray); //sending 1024 values
```

I referred this.

Hm… FFT data are in a Buffer (not on buses).

`getnSynchronous`

is only for control buses, not buffers. So, if you’re only running an FFT synth, then `getnSynchronous`

can’t access the buffer data.

The sccode example uses a Synth to write the buffer data onto a series of consecutive bus numbers – after transferring the data to buses, *then* `getnSynchronous`

can operate.

So… are you running a transfer-to-buses synth? Or only the standard FFT?

Definitions is below.

I thought , if i play some synth ( just SinOsc is fine) then i could get FFT data.

But var fftArray= ~kbus.getnSynchronous(~buffersize2_fft);

fftArray has no value.

```
~buffersize_fft= 2048;
~buffersize2_fft= ~buffersize_fft.div(2);
~kbus= Bus.control(s, ~buffersize2_fft);
~fftData= Synth(\fft_synth, [\in, 0, \bus, ~kbus]);
//for fft
(
SynthDef(\fft_synth, {
arg in= 0, bus;
var z= Mix( In.ar(in, 2) );
var chain= FFT( LocalBuf( ~buffersize_fft ), z);
Array.fill(~buffersize2_fft, { |i|
var a= Unpack1FFT(chain, ~buffersize_fft, i);
var d= Demand.kr(chain>=0, 0, a);
Out.kr(bus+i, d.min(1));
});
}).add;
);
```

Check the order of execution. The `In`

synth needs to come *after* its source.
