The use of inch and outch with nchnls isn't clear to me from those
topics in the manual.  For instance, I can't get the csd below to
work.  I have tested an instrument that is set for nchnls=8 that works
correctly with things like outc ganull, ganull, ganull, ganull,
asound1, asound2.

It would seem that nchnls can be set to other vaules than those
documented in the manual.  It states

"nchnls = (optional) -- set number of channels of audio output to
iarg. (1 = mono, 2 = stereo, 4 = quadraphonic.) The default value is 1
(mono). "

What isn't clear from this is if any value is possible and in what
circumstances.  A related concern is that in seems to need out and ins
seems to need outs.  Is some kind of overall clarification on this
available, or am I just not seeing it.  If not, it would be helpful.

[This is probably a follow-up to a thread that Joachim Heintz was
helping me with more than a month ago that I let drop.  Apologies to
you, sir.]

Any (integer) value is valid.  Clerly ther are memory implications.....

You said you can't get the csd you have sended to work.
What are the error messages?

Here is the log. I'm not sure why it writes every line twice (because
of the double samples?):

That says that the output device cannot deal with the 8 channels.  I tried
your .csd to disk and it worked.  But I do not have any 8-channel devices
to test real-time

I currently have my E-MU 0404 set up with 2ins and 16 outs.  It seems
that when I am using real-time ins and outs I can only have as many
outs as I do ins, so in this case I can't get more that 2 outs because
I have 2 physical ins.  So this does not work:

sr = 44100
ksmps = 8
nchnls = 4

instr 1
anull = 0
a1 inch 1
outc anull, anull, a1, a1
endin


Neither does this:

sr = 44100
ksmps = 8
nchnls = 4
0dbfs = 1

instr 1
ain1 inch 1
outch 3,ain1, 4,ain1
endin


Both get:

 *** PortAudio: error: -9998: Invalid number of channels


It above will run with:

nchnls = 2
outch 3,ain1, 4,ain1

though the outs are discarded as documented in the manual

nchnls = 2
outch 1,ain1, 2,ain1

works fine.


This plays fine (though I don't have -iadc enabled):


sr = 44100
ksmps = 8
nchnls = 6
0dbfs = 1

instr 1
anull = 0
a1 oscil .25, 440, 1
outc anull, anull, anull, anull, a1, a1
endin



f1 0 16384 10 1
i1 0 1
e


I can trick my software mixer into thinking I have 4 physical ins.
The above instruments behave the same, but with a four channel
limitation rather than 2.

-Charles

I'm pretty sure that this is the case with asio, i.e., your number of
inputs must match your number of outputs which is quite frustrating,
I'm not sure how this works with other audio drivers.

I've been working on this problem, and have a solution for my setup:
windows XP, EMU 0404 soundcard.

When I originally posted I had my E-MU 0404 set up with 4 mono ins and
16 virtual outs mixing to 2 physical outs.  It seems that when I am
using real-time ins and outs I can only have as many outs as I do ins,
otherwise I get:

 *** PortAudio: error: -9998: Invalid number of channels

This is only an issue when I am using real-time input.  I can have as
many outputs as my soundcard will allow when using csound for
synthesis to multiple outs.  This works with the described set up
above:

a1 oscil .05, 440, 1
outc a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1

I'm guessing this IN/OUT issue when using -odac -adc has to do with
the way the EMU software mixer tells csound what's avaliable (an ASIO
thing as Rory says). With the E-MU mixer each input is mapped to an
ASIO Host.

What I've done is mapped the inputs to multiple outputs some of which
are beyond the number of channels strips I set in the mixer (16 out of
a possible 32).  I set up four inputs, two which are physical and two
which are S/PDIF.  Each channel is actually mono, but I have the mixer
set them as stereo.
- The first PCI card in (L) is mapped to ASIO Host 1/2 and 25/26.
- The second PCI card in (R) is mapped to ASIO Host 3/4 and 27/28.
- The first S/PDIF in (L) is mapped to ASIO Host 5/6 and 29/30.
- The second S/PDIF in (L) is mapped to ASIO Host 7/8 and 31/32.

This seems to work fine for csound, I don't get any error messages and
csds like those below work.  I haven't tested my other music software
to see if this causes any havoc.

a1 inch 1
a1 = a1*(1/16)
outc a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1,a1

a1 inch 1
a1 = a1*(1/4)
outch 1,a1,2,a1,15,a1,16,a1
