Hi Jeremy,
I've got a USB soundcard that I'm using for my "pro" interface: a
Lexicon
Lambda. Works well OOTB with the sound_usb_audio module. Capable of sr
48000.

Hey all,
So the continuing saga is this: still no luck getting Pianoteq with JACK
to
equal or spank with superiority the performance
of PianoTeq w/ALSA alone
on
my system.....
I found the following information: the info from the /proc/asound output
that Paul asked me to check out confirmed that at comparable settings,
JACK
choked where ALSA smoked. I had ALSA down to a
period of 64 and 3
periods/buffer (hardware bufsize of 192) at a sample rate of 48000. The
same
setting of jackd ('jackd -dalsa -dhw:0,0
-r48000 -p64 -n3 -S') didn't
agree
with Pianoteq....
So...here's my dilemma. I have a live show coming up where I'd prefer to
use
the superior harpsichord sound of Pianoteq, but I
don't want to risk a
lock-up or xruns or worse in a live concert. So I would have to use
ALSA...BUT....I also need to switch to playing a live kalimba through
some
Csound effects right after playing a harpsichord,
and Pianoteq under ALSA
will not stand for another app opening and sharing the soundcard like
JACK
will allow (ALSA will block I/O).
So what can I do?
Best,
AKJ
Hello Aaron,
Might have missed something but what kind of soundcard are you using?
And why the -S option?
Best,
Jeremy
