Hi Fons,

As robin said
-+rtaudio=jack
The buffer size needs to match though. If a JACK plugin is set up in
ALSA you don't have to use a particular -+rtaudio option, though alsa
will do and the buffer size issue is gone.
> * using Ninp input ports and Nout output ports,
If you just mean specifying a particular number of input and output
ports:
nchnls = 
sets the number of both input and output, unless you also use:
nchnls_i = 
which sets a different number of input ports.
> * not autoconnecting any ports,
...
Within Csound you have at least two ways to use JACK. Either by
-+rtaudio=jack and then using the normal input and output opcodes like
out, in, outs, inch, ...
Or you can use the Jacko opcodes which have their own setup. I believe
they _HAVE_ to be connected inside the Csound orchestra header though.
Here's the overview of those opcodes and more detail about the Jacko
system:

HTH.

Best wishes,
