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. On Sun, Aug 29, 2010 at 10:58 AM, Christoph Kuhr christoph.kuhr@web.de wrote:

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?
