Sorry, I didn't mean to undersell the sophistication of RT/RD; but I understand. The Mellotron was from a different era, and digitization gives you a lot of power. I want to explore these as soon as I am satisfied with my MIDI setup and the UI for BiB.

BTW, on the issue of quad core processors, I've been monitoring the use of the cores on my machine (Athelon quad-core, 64-bit fetch)\, and I can see a reason for BiB to benefit from them. I notice that the NT kernel seems to take one core (#1) and about 18 threads; all of the systems jobs -- around 30-40 with maybe 200 threads -- take the #0 processor; and BiB flips between processor #2 and #3 (only one at a time as far as I can see, but I'm not sure what is going on) with around 20 threads.

Intel's Hyperthreading and AMD's Framewave (which would give a couple of virtual cores to each physical core) would presumably help manage the threads -- I don't know how predictive these can be, but there is enough going on on the computer overall that it is probably very useful to have them. Since BiB would have its own dedicated core, there is less likelihood of it hanging or delaying because of other jobs in the system.
