Hi,
I have jack running on a windows machine with the net driver (slave).
The master is fedora 18.
The relevant incantations (taken from .jackdrc) are:
Master: jackd -S -dalsa -dhw:0 -r44100 -p256 -n3 -H -M -Xseq
Slave: jackd -X winmme -dnet -i2 -o2 -C8 -P24 -i8
... both controlled by qjackctl
This has been working pretty flawlessly for a few months but when I
noticed with a certain instrument on the slave there was some midi
latency, I decided to try fiddling with master -p (frames/period). I
shut both slave and master down, changed period from 256 -> 128 and
fired up the master -- all great, played some music , made a few live
recordings etc.
Then I started the slave (same command line) and noticed massive xruns
(on the slave) -- so ... I change it all back to -p 256 but the xruns
are still present (on the slave).
Poking around a bit, I opened up the "options" on the master and it says
Frames/Period: 256, I open up options on the slave, and it is grayed out
but says: Frames/Period: 512.
My questions are simply:
1) is qjackctl reporting this correctly on the slave?
2) if so, how or why would they be different?
3) is this why I'm seeing massive xruns?
Any help appreciated.
David

No, qjackctl is displaying some old values, opening up the Messages
window -> Status tab shows the correct value (256)
3) is this why I'm seeing massive xruns?
nope ... while looking at the Status tab I noticed DSP load was between
95% and 100%. I found the offending windows program and all is well again.

I just finished building a semi-stable working environment made up of:
Linux:
- jackd
- patchage (to visualize and manage the connection graph)
- jkmeter, gmidimonitor
- non-session-manager (and the ever essential JACKPatch, without
which I would have given up on linux audio)
- ardour3 for all live recordings and all mixing -- just starting to
be able to see it as stable replacement for Sonar X1. I miss some things
for sure and had to fall back to X1 a few times for a paid job with a
deadline, but ... it's almost there and high time for me to contribute
some $$.
Windows:
- loopbe30 (virtual midi ports)
- jackd
- Plogue Bidule (vst host and connection routing manager)
- Various software instruments e.g., EastWest, Vienna Instruments,
Garritan etc.
- Notion4 (notation software)
The rest are becoming obsolete:
- Vienna Ensemble Pro 5 (very impressive piece of software)
- Sonar X1
I've had success using wine and/or vsthost for many of my windows VSTs
but the major deal breakers were always eastwest and vienna because they
require a dongle so I just manage all windows stuff in windows and route
everything using jackd(net).
