Have a question... I'm trying to move ever towards eliminating Winblows. I have to come up with a *bullet proof* method of running a solid midi seq alongside the Delta for my fx and live audio processing. None of the midi apps out there seem to work very well with softsynths used for the GM instrument set. Fluidsynth, etc has it's issues and so on. I don't own any hardware modules and don't want to if I dont have to. I have been using Roland Virtual sound canvas, Yamaha sy-xg, wingroove, Edirol Hypercanvas, etc on Win XP with Sonar for this function and it works well. I'm wondering, how might I run a SBlive next to the Delta and not have them conflict. I guess I would have to run the SBlive in the OSS layer? Then suffer from realtime issues again? Point being in previous experimentation, the SBlive with a sound font loaded, at least behaves more like an actual piece of hardware...It might play a little nicer with Muse or Rosegarden... R~

i have my onboard sound card (ens1371) running at the same time as my audiophile card. both are using alsa and i run jack ontop of my audiophile. it's pretty easy to do and i'm not sure why more people don't do it. --Andrew

So the second card just has access direct to the alsa drivers but does not affect Jack's operation at all on the other? R~~

i've never noticed any problems with jack. basically, alsa runs on top of both cards. i tell jack to use card 0 (my audiophile) and it does happily. i still have card 1 available, so when i want to output to that, i tell the program to output to that one. kinda looks like this: jack -> alsa's ice1712 driver -> card 0 alsa'a ens1371 driver -> card 1 (just wrote that out to point out that the alsa driver has access to the card, not the other way around. technicalities/sorry if i mis-understood ;)

Actually, the ens1371 is a particularly bad card for/good example of maintaining sync at the sample level. The (at least the one I have) ens1371 has a bug where the sample rate is one short (or long, I forget) on the capture side. The result is when you play back a large audio file at 44.1 it's not the right length. The difference over an hour is about 2 seconds.
