I've just an simple P4 (2.25) , 1gb ram, maudio > audiophile card. That might be part of it. I run a dual core 64bit machine and have 4G memory. I also use it ONLY for music. Internet and office stuff are all done on a cheap general purpose machine. > What Jack settings do you use? Mostly the default settings. For just Rosegarden and Zyn. I set 64 frames / period which gives a latency of 2.9mS, if I've got a lot of other stuff running as well, or if I'm using the most complex patches I go up to 128 frames / period, which is 5.8mS. On very rare occasions I have to go up to 11.6mS - this is what I had to have most of the time with Zyn 2.2.1, although then it was zombies that were the main problem rather than xruns :( -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
