Well, I am having the same (almost) problem. I have not been able to get as far as filtering, though. I have a brand new Mac Mini, OSX 10.5.6 (Intel Core 2 Duo 2.26 Ghz, 4gb DDR3, 300 gb drive) Toast 10.0.2, CD Spin Doctor 6. The music gets recorded on the Mac drive (from the peamp to the ADS Instant Music box to a USB port), but as soon as I try to define tracks it crashes. Help!
