I recently bought the TASCAM US-144 believing that it would be compatible with my macbook which runs Mac OSX 10.5.2. I brought it home, excited to be able to record decent audio instead of with the internal mic. but lo and behold, nothing seemed to worked. Long story short, the interface isn't compatible even though it is listed as Leopard compatible. It's a great looking piece of hardware and I was really enthused about using it with Logic Pro but I guess i'll just save it to use on my windows partition and wait for a new driver. In the meantime, I would like to know which Audio/Midi interfaces are 100% compatible with Leopard and Logic Pro 8/Garage Band and under $300. _DTA
