Hello,
I was trying the Focusrite Saffire 6 USB with
csound and it seams to have a problem with
multichannels. Csound gives an error when using
the Focusrite with more than 2 channels:
PortAudio: selected output device 'Saffire 6USB'
*** PortAudio: error: -9998: Invalid number of
channels
Failed to initialise real time audio output
inactive allocs returned to freespace
end of score. overall amps:
0.0 0.0 0.0 0.0
overall samples out of range:
0 0 0 0
1 errors in performance
This seams to be an error from csound because when
using Digital Performer it recognizes all four
channels.
Any ideas what could be the problem?
I'm running Csound 5.17 (doubles) with OSX 10.6.8
Thanks,
Luis

Sounds like a problem with portaudio. Have you tried Jack or the AuHal module?

Luis, also: maybe it's to do with different numbers of available ins and outs. You can set nchnls_i = X to set a number of input channels that is different to nchnls.

Indeed. It works fine with Jack. Could it be that the problem is due to the interface having 4 outputs but only 2 inputs?

Thanks Victor. I didn't know about this variable. I tried like this
but it didn't work: sr = 44100 ksmps = 64 nchnls = 4 nchnls_i = 2

| Not sure what the problem is, but that is supposed to select different numbers of out channels. Victor On 19 Apr 2012, at 14:28, luis antunes pena wrote:

| yes, it's a bug in our portaudio module, and I fixed it in GIT. My impression is that rtauhal does it correctly. And of course you can use jack. On 19 Apr 2012, at 14:28, luis antunes pena wrote:

Great Victor. Thank you very much. I'm using now Jack, but will try
rtauhal later. Best, Luis Am 19.04.12 18:11, schrieb Victor Lazzarini: yes, it's a bug in our portaudio module, and I fixed it in GIT. My impression is that rtauhal does it correctly. -- -- http://luisantunespena.eu |
