Hi,

working on examples for the manual, i wanted to try out an example using:
nchns_i and inq.
Is the nchns_i opcode fully operational yet?
In /manual/opcodes i see it written as nchnls_i.html, but i think it must be
nchns_i (without l) right?

The error i get when running the csd -using the old parser for more
information -  below is:

--> error:  failed to find =.?, output arg 'nchns_i' illegal type, line 14:

The csd:



; Select audio/midi flags here according to platform
-odac  -idac --old-parser ;;;realtime audio I/O
; For Non-realtime ouput leave only the line below:
; inq.wav -W ;;; for file output any platform



sr  = 44100
ksmps  = 32
nchnls  = 2	;2 channels out
0dbfs   = 1
nchns_i = 4	;4 channels in

instr 1 ;4 channel in, two channels out

adel   linseg 0, p3*.5, 0.02, p3*.5, 0	  ;max delay time = 20ms
adel2  linseg 0.02, p3*.5, 0, p3*.5, 0.02 ;max delay time = 20ms

endin

The variable is called nchnls_i
See Engine/csound_orc_compile.c or Engine/rdorch.c

I believe that it is working in all cases -- if not I want to know

Ah.
in the manual it is written as nchns_i.
But i can change that.

Bigger issue is that when i run my csd - and it should run for 10 seconds -,
it hangs. 
Because i override the CsoundOptions with Jack settings (-+rtaudio=jack
-odac -iadc) i can see in gladish that 2 inputs and 2 outputs are created
and not 4 inputs and 2 outputs.
In gladish i can manually make the jack connections from inputs to app to
outputs. But in my csd i ask 4 inputs, but they are not created.
When i do nchnls = 4 then 4 inputs and 4 outputs are created. 
I can not give nchnls  = 2 and nchnls_i = 4, it seems that nchnls_i = 4 is
ignored.

I cannot provoke any errors; it sets 4 channel in and 2 out.  I do not
have a quad mic so stopped at that point.

all right John, thanks for testing. I will try to find the error on my side
later.
 I will upload the example as example of inq into the manual.
Also i will change all mentioning of the nchns_i page to nchnls_i, as seen
on http://www.csounds.com/manual/html/nchnls_i.html

thank you, bye,
menno
