The more channels you've got on FireWire, the more bandwith it takes and the more likely you may have problems. > The FF800 setting has these 4 Limit Bandwith, the lowest setting is 8 analog channels. 4 times more than on the your MacBook or PowerBook stereo output. > That's why according to RME, the Apple Stereo output will give you lower latency and less cracks! > > If you have more news on the FF400, please let me know as i'm interested in that one too, instead of my FF800. Hi, I have used Ivory with a PB 1,33, 2Gb ram and FF800 at 128 buffer with fine results. Well, sometimes with playing many (16 or more ?) notes like with the sustainpedal pressed it gave strange results. My experiences are believe ram and speed of HD are the most important factors, then CPU overhead. Ivory's pianos are 10Gb presets... Dont think your problems are related to the bandlimit Now on a MBP Ivory seems to work better, but the Clavia Nord Stage both sounds and feels much better and never crackles... that is even with a 32 mb preset...
