	I sent the following message to the QuteCsound forum. Andres believes the problem is with csound, so here it is: Begin forwarded message: From: Louis Cohen Date: October 20, 2010 10:47:32 AM EDT To: qutecsound-users@lists.sourceforge.net Subject: Trouble with Quad sound I am having difficulty using QCS to output quad sound. I'm wondering what I might be doing wrong -- perhaps some QCS settings? Environment: MacOSX 10.5.8, MacPro (Intel, 4 quad cores), QuteCsound 0.6.0 When I run the following csd, I get highly granulated sound. Output to channels 1 and 3 goes only to channel 1 (left front.) Output to channels 2 and 4 goes only to channel 2 (right front.) The csd crashes if I use portaudio, and only runs when I select coreaudio. My audio device is a 4-channel USB device made by Native Instruments ("Audio Kontrol 1") If I "Run in Term" I get the same result, granulated sound, nothing to channels 3 or 4. If I modify the csd to specify 2 channels and modify the score to send only to channels 1 and 2, I get clean sound, but of course only to the left and right front channels. If I run the same csd under MacCsound I get clean sound, correctly sent to all 4 channels.

	It's strange that portaudio is crashing. Did you try using a different program, like PD to see if it works (it also uses portaudio). MacCsound uses its own IO, so it is probably doing the right thing. The coreaudio module is probably not. But I would have thought that portaudio would be OK. Could you run it on the terminal and see if there are any messages from portaudio before it crashes?

	Victor and John, thanks for looking into this problem. I used QuteCsound's configuration option to select portaudio and ran the test in Terminal mode. No crash, but no sound. Apparently portaudio doesn't like something about the number of channels. Here's the output. Since an error message possibly refers to the code in the csd, I'm providing the csd again. John, you mentioned that the buffer sizes seem small. What do you recommend, and how can I control the buffer sizes? best, Lou sr = 44100 ;samples per second for sound kr = 4410; 100 nchnls = 4 0dbfs = 1 instr 1 print p4 asig oscil 0.1, 400, 3 outch p4, asig endin f3 0 513 7 1 256 1 1 -1 0 -1 255 -1 1 ;square wave i 1 0 2 1 i 1 2 2 2 i 1 4 2 3 i 1 6 2 4 Last login: Thu Oct 21 06:46:25 on console % /var/folders/r6/r6Z-7IuZHzexTY-MxH9LPU+++TI/-Tmp-/ qutecsound_run_script-WYy673.sh ; exit; /var/folders/r6/r6Z-7IuZHzexTY-MxH9LPU+++TI/-Tmp-/ qutecsound_run_script-WYy673.sh: line 3: cd: /Volumes/A_G5Int1TB/ Documents1/Lous compositions/granularImprovisor/wiimoteimproviser echo "/usr/local/bin/csound "/Volumes/A_G5Int1TB/Documents1/Lous: No such file or directory PortMIDI real time MIDI plugin for Csound PortAudio real-time audio module for Csound virtual_keyboard real time MIDI plugin for Csound 0dBFS level = 32768.0 Csound version 5.12 (float samples) Jun 4 2010 libsndfile-1.0.21 UnifiedCSD: /Volumes/A_G5Int1TB/Documents1/Lou's compositions/ granularImprovisor/wiimoteimproviser/quadtest.csd STARTING FILE Creating options Creating orchestra Creating score orchname: /var/folders/r6/r6Z-7IuZHzexTY-MxH9LPU+++TI/-Tmp-//csound- OVOSY1.orc scorename: /var/folders/r6/r6Z-7IuZHzexTY-MxH9LPU+++TI/-Tmp-//csound- Ik7qdQ.sco rtaudio: PortAudio module enabled ... using callback interface rtmidi: PortMIDI module enabled orch compiler: instr 1 sorting score ... ... done Csound version 5.12 (float samples) Jun 4 2010 midi channel 1 using instr 1 midi channel 2 using instr 1 midi channel 3 using instr 1 midi channel 4 using instr 1 midi channel 5 using instr 1 midi channel 6 using instr 1 midi channel 7 using instr 1 midi channel 8 using instr 1 midi channel 9 using instr 1 midi channel 10 using instr 1 midi channel 11 using instr 1 midi channel 12 using instr 1 midi channel 13 using instr 1 midi channel 14 using instr 1 midi channel 15 using instr 1 midi channel 16 using instr 1 0dBFS level = 1.0 The available MIDI in devices are: 0: A-80 (CoreMIDI) 1: Audio Kontrol 1 VirtualIn (CoreMIDI) PortMIDI: Activated input device 0: 'A-80' (CoreMIDI) orch now loaded audio buffered in 64 sample-frame blocks reading 512-byte blks of shorts from adc (RAW) PortAudio V19-devel (built Feb 12 2010 09:42:54) PortAudio: available input devices: 0: Built-in Microphone 1: Built-in Line Input 2: Built-in Digital Input 3: Audio Kontrol 1 PortAudio: selected input device 'Audio Kontrol 1' PortAudio: available output devices: 0: Built-in Output 1: Built-in Line Output 2: Built-in Digital Output 3: Audio Kontrol 1 PortAudio: selected output device 'Audio Kontrol 1' WARNING: buffer size should be an integer multiple of ksmps in full- duplex mode *** PortAudio: error: -9998: Invalid number of channels Failed to initialise real time audio output inactive allocs returned to freespace end of score. overall amps: 0.00000 0.00000 0.00000 0.00000 overall samples out of range: 0 0 0 0 1 errors in performance Press return to continue On Oct 21, 2010, at 3:07 AM, Victor Lazzarini wrote: > It's strange that portaudio is crashing.

	Victor, Regarding testing quad with other software, I have no knowledge of PD although I have a version currently on my system. If you could send me a simple PD file I would run it on my system. I do use Logic extensively and there are no problems running quad. I suspect that Logic uses coreaudio, however. best, Lou On Oct 21, 2010, at 3:07 AM, Victor Lazzarini wrote: > It's strange that portaudio is crashing.

	That's the problem, portaudio seems to think your device does not allow 4 channels. Does it have a different number of inputs and outputs? If so, that could be the problem. For this there are two solutions: if you are not using input, just remove -iadc from the qutecsound configuration. Otherwise, you can try setting nchnls_i = 2 to set the number of input channels to be different to the output.

	Victor, This is definitely the right direction. First, nchnls_i in my csd gave me a syntax error when I first tried it, but after finding the setting below, it was accepted by csound. This is confusing to me. I have no model in my mind about what's going on here. However.... After trial and error I found some settings that work for my immediate application: Using portaudio and running with QuteCsound (not in terminal mode): Input device NONE (even though the Audio Kontrol device actually has one, which I'm not using presently.) Output device dac3 (which specifies the Audio Kontrol 1 device.) RT MIDI module NONE (although the Audio Kontrol device has MIDI in and MIDI out.) The result is a stutter on the first sound, then clean sound afterwards, sound showing up on all four channels. I'm not sure what I would do if I needed audio input or MIDI, but for now I've got what I need. Any hints about how to deal with audio input and MIDI? I never really paid attention to the QuteCsound configuration before. The defaults worked just fine. Now that I'm looking at all the options, it seems that some explanation would be quite useful. For example, what happens when various combinations of "Use QuteCsound options" and "Ignore CsOptions" are checked or unchecked? What is the difference between portaudio and coreaudio? What is "buffer size" all about? Same for "HW buffer size"? What happens if I check or uncheck these options? etc.... best, Lou On Oct 21, 2010, at 8:18 AM, Victor Lazzarini wrote: > That's the problem, portaudio seems to think your device does not > allow 4 channels.

	Lou, nchnls = 4 nchnls_i = 2 should work for you (it's been in Csound since 5.12). It works here. RT MIDI can be set to portmidi (it's independent of audio). The 'ignore CsOptions', ignores options set in , the use QuteCsound options uses the options on the configure window. Otherwise you can set Csound options in CsOptions as usual.
