I thought my processing loop in Cabbage could handle multichannel
signals. And I can remember experimenting without any problems in the
past. Now I get some high pitched artefacts on all channels. Does the
processing function presented below look ok to you guys? (note that
nchnls==getNumOutputChannels())
I'm testing with a simple oscil instrument, outputting the same signal
to each channel. I have nchnls set to 8 and I'm using outch 1-8 to
output the samples. The odd thing is that CSspout[channel+pos] changes
value every second channel. My understanding would be that it should
stay the same until channel returns to 0 and the for loop starts all
over again? getNumOutputChannels() returns 8, as does
csound->GetNchnls().



void CabbagePluginAudioProcessor::processBlock (AudioSampleBuffer&
buffer, MidiBuffer& midiMessages)
{
float* audioBuffer;
    for(int i=0;iGetKsmps())
            {
                csCompileResult = csound->PerformKsmps();
                csndIndex = 0;
            }
            if(csCompileResult==OK)
                {
                for(int channel = 0; channel < getNumOutputChannels();
channel++ )
                    {
                    audioBuffer = buffer.getWritePointer(channel);
                    pos = csndIndex*getNumOutputChannels();
                    CSspin[channel+pos] = audioBuffer[i]*cs_scale;
                    audioBuffer[i] = (CSspout[channel+pos]/cs_scale);
                    }
                }
            else
                buffer.clear();
        }
}

I don't have enough channels on my sounds card to test a simple API
version(but I guess I don't need if I'm only checking the contents of
CsSpout?). Anyway I'm wrapping it into an 8 channel VST. Is my
assumption that CSspout[channel+pos] should remain the same until it
has looped through all 8 channels correct? If I log the variables it
looks like this:

csndIndex:0 Channel:0 Value:0
csndIndex:0 Channel:1 Value:0
csndIndex:0 Channel:2 Value:0.0283748
csndIndex:0 Channel:3 Value:0.0283748
csndIndex:0 Channel:4 Value:0.0567268
csndIndex:0 Channel:5 Value:0.0567268
csndIndex:0 Channel:6 Value:0.0850331
csndIndex:0 Channel:7 Value:0.0850331
csndIndex:1 Channel:0 Value:0.113652
csndIndex:1 Channel:1 Value:0.113652
csndIndex:1 Channel:2 Value:0.141797
csndIndex:1 Channel:3 Value:0.141797
csndIndex:1 Channel:4 Value:0.169828
csndIndex:1 Channel:5 Value:0.169828
csndIndex:1 Channel:6 Value:0.198098
csndIndex:1 Channel:7 Value:0.198098
csndIndex:2 Channel:0 Value:0.225831
csndIndex:2 Channel:1 Value:0.225831
csndIndex:2 Channel:2 Value:0.253382
csndIndex:2 Channel:3 Value:0.253382
csndIndex:2 Channel:4 Value:0.281097
csndIndex:2 Channel:5 Value:0.281097
csndIndex:2 Channel:6 Value:0.308214

I'll see if I can throw together a quick command line app now..

I mean the Csound command, not your own app.

Anyway, what you printed looks 2 channels to me.

Unless I'm mistaken, that is what I'm doing?

pos = csndIndex*getNumOutputChannels();
hostBuffer[i] = CSspout[channel+pos]/cs_scale;

When I try to increase the number of channels in jack and start the
server it says no can do. If I just run with nchnls=8 with jack
started in stereo I get:

 0: dac:system:playback_ (system:playback_)
 *** rtjack: error connecting output ports

How do I set up more channels that I have?

I missed that line. ..

yes, it’s trying to autoconnect. I need to add something to disable it. Anyway, you could test it to a file. I’ve just done it on OSX and
it’s fine.

Fine here too. Ok, must be elsewhere in my code, and hold on. Yes, I
know what it is now. Buried somewhere I bet I have used csound_prams
to set the channels! Arrgghh. Why must I keep cutting myself with
Occam's razor. I really wonder about me at times!
