OK.. Here's a quick update. On the desktop, I have now installed Ubuntu Studio 12.04 + a few bits from kx-studio. I experimented with the full kx-experience and found the way it took over the whole audio system - putting everything thru jack, and making everything a ladish session a bit much for me - but I appreciate the work that has gone into it all.. Anyway, it all seems to be working much better than avlinux was on that system - no crackles on linuxsampler, for example. Pulse and jack seem to be playing together reasonably well. On the "live" laptop - eeepc 701, I have done some more experimentation and come up with some very surprising (to me) discoveries. 1) Running whysynth in ghostess led to a nasty lockups when playing too many notes (CPU couldn't cope). 2) ams - ok as monosynth (but a bit heavy for this little computer), no really feasible to use as polyphony 3) amsynth - works very nicely, but maybe not able to create the pad sounds etc. that I need. 4) Carla - too fiddly (for me) for live use. Now, here's what I seem to have come down on. Amazingly all these run on this little computer at the same time, and are capable of full polyphony with no major xrun issues (1024 samples on jackd - might be possible to reduce this further, but it is perfectly usable for a midi keyboard): 1) setBfree - lovely! 2) yoshimi - amazing! 3) qsampler/linuxsampler (with rainpiano gig at the moment) - stupendous! CPU idles around 45%, but only peaks at 60% with the first two (what I considered pretty heavy-duty) synths. setBfree only goes up to 48%. I think linuxsampler is the most sensitive - if I go too overboard on the expression pedal, I can crash the whole thing - so either I don't plug in an expression pedal for live use, or I don't use it... Might investigate soundfonts for a piano sound if I need it. A|ll are running on different midi channels (I had some issues with Beatrix which segfaulted if I tried to use a midi channel it wasn't connected to - so setBfree is a great addition). The main issue I have at present is with yoshimi - i would like to change program (and ideally bank) using the midi controller, but this doesn't seem to work with the 1.0 version from kxstudio. Is this not possible with yoshimi at present, or is there a development version I could use?
