I've been tinkering recently with my Eee running
Xubuntu and a newly
acquired M-Audio Axiom 49 USB Midi Keyboard; I think it'd be just about as
great as it could get if I could use the Eee as a synth engine via
XynAddSubFX or similar - Unfortunately, I've been unable to tweak my JACK
settings to the point that all stutters and chops have been eliminated. I
understand that the Eee specs are quite low (900mhz proc, 512MB RAM), but
watching my resource usage while I'm playing shows the processor at less
than 50% and RAM holding steady at 60% or so - This would lead me to believe
that my problem is configuration related.
Any other Eee users out there had any luck getting JACK fine tuned to the
Eee? Since we're all working on nearly identical hardware, perhaps we could
swap configs?
I just found this video - an eee running supercollider and jack!

Also I found this benchmark:
http://novosche.blogspot.com/2007/12/eee-pc-benchmark-test-asus-eee-pc-4g.h…
It's notated kind of inscrutably but I think it can be translated
thusly. Each cell shows average percentage of CPU to run the given
number of supercollider ugens / synth voices on the given platform.
So lower is better.
128 ugens/ | 256 ugens/ | 384 ugens/ | 448 ugens/
32 synths | 64 synths | 96 synths | 112 synths
HARDWARE | | |

What this appears to show is that the EEE is roughly equivalent to a
powerbook G4 1.67 GHz, for this particular benchmark. And almost half
the speed of an intel macbook pro 1.84. That's not bad considering
the G4 *still* costs more on ebay than the EEE does new.
There's also a test of the number of synth voices at which the EEE and
the macbook pro each reach 66% CPU. If I read it right, the MBP can
do 800 voices (3200 ugens). The EEE can do 356 (1424 ugens).
