Today i had closer look:

I have 26i 26o for the system
And i have netjack with 24o 2i
So pd is always limited to 126-78(26+26+24+2)ports no matter in which combination i try ins and outs... Seems to be a jack issue...

I have tried with the pd config, with 40 ins and outs. (see attached
image) and works. And I also can run other apps like japa,
meterbridge, mocp, whatever.

Apparently the thing in jack is:
- each application can register as many in/outs as they demand (when
you change pd to 40/40) those appear in the qjackctl frontend
- there should be a maximum defined somewhere, I couldn't find it
easy, must be in jack documentation
- for the audio card, jack can only send ins/outs at the max of the
audio card true in/out - obviously =P

Report if you have any luck.

Best regards,
Pedro

No my mistake, I was looking at device input channels, so their
directly binded to the soundcard, hence they are not virtual.

I'm gonna try another workaround...

which one do you mean?
i only have it in german...
there is something like system-input/output ports, but they configure
alsa, not jack itself ?!?
and another item max port, which is 256...

ahhh.. in qjack there's a setting (qjack > setup) for max input and
output ports, if you tell him nothing its running "default" which is
probably the values you reported.

Yes, i did so too...
It seems to me, that jack is limited on his total ports...
netsource 2i 24o
Pd 24i 8o
System 24i 26o

This is running so far
But any other jack client can connect anymor... Not jack rack, not japa
etc...

Has the number of ports to do with the used bufferlength in any way... I
mean do they influence each other?

I've just opened jack (via qjackctl) and pdextended (rt enabled in an
rt kernel).

It seems to work, I tryed 48 out and in and they all appear on qjack
frontend GUI, I can connect and route any combination of inputs.

What I did was go to Pd main GUI > media > Audio Settings > and change
number of channels numberbox to 48 in and same for out.

Have you tryed this way?



Best regards,
Pedro
p.s.: although its working Im testing this in a really lame netbook,
so It gets all scrambled and slow with so many ins. I can try in my
laptop and confirm if the aforementioned procedure works too.

Hi everyone,

I have a problem using jack audio...

I want puredata to register 48channels of capture and 8 of playback.
But i get only 18channels running.
Else pd says:
"error: JACK: unable to connect to JACK server
JACK: jack returned status 17
error: JACK error: cannot deliver port registration request
error:JACK: can only register 18 input ports (instead of requested 48)"

Is pd limited to 26 channels IO?
