I was running a Dell CPXj 650mhz with a crappy old ESS Maestro 3 sound
chip for awhile. I could get reasonable latency but not real liveable
playing a live instrument thru. Anything under 1024 it did not like
much. These laptops are fairly robust and run about $450.00 US now if
you look. I also bought a CII docking station that could house 2 PCI
cards. I used a SBlive 5.1 for $19.00. The docking station I got on Ebay
for $60.00. THis was a better rig. The SBlive would handle lower
latency. But I was also running GUI (Fluxbox) and Qjackctl, Ardour or
Alsa Modular synth with LADSPA plugs.

Thanks for taking the time to read this.
