I've been working for a while in a piece for real-time synthesis /
sample playback and a piano controller (and pedals, etc, etc). I
normally play with my laptop, a dual core lenovo t61 running the latest
rt patched kernel and: linuxsampler at 96 voices max (4 different piano
samples), two instances of the supercollider synthesis engine doing
synthesis and spatialization, a program in supercollider controlling the
whole thing (including the GUI feedback screen for the performer),
jconvolver for convolution reverb and ambdec for ambisonics decoding.
All with a PCMCIA RME card and a Multiface running at 128x2 48KHz.

It can glitch but if it does it is because it has actually run out of
cpu (and I have had a couple of instances in rehearsal where I'm playing
textures so thick that the supercollider scheduling queue has filled up
with not so good results, argh :-)

All in all quite reliable (I played an earlier version of the piece in
last year's LAC).
