Very low latencies?[*] Then you _will_ need the realtime preemption patches or you will have to live with xruns. Not so low latencies? Vanilla kernels > 2.6.26 will probably work just fine. It also depends on what hardware mixture you have on your computer and how it is (or is not) tuned. A caveat is that the realtime preemption patches for 2.6.26.x don't seem to work too well (midi problems when used with external controllers). And for 2.6.27.x there is nothing even usable yet (last time I looked). The latest "stable" preemption patches are for 2.6.24.x, which is regretfully now too old for many hardware configurations (and even for some software, like the newer X servers). In both cases you will need a working Jack and you will need to run it with realtime priority (which has nothing to do with the realtime preemption patches). Hmmm, so am I now perpetuating the rumor? :-) -- Fernando [*] 5-10 mSecs? There is no hard boundary...
