Finally... a universal binary, interface overhaul, and a limited but interesting ability to host MIDI files as well as AudioUnits. Check out the demo tracks... you will be impressed with what Rax can do with just Apple DLS synths and matrix reverb. Add a sequencer and some spiffy AUs like Automat and the Expert Sleepers set, and Rax would be shareware music nirvana. As it is, it does all it used to do and a bit more, but now on your Core Duo. :D It also seems to be less of a CPU hog than version 1.2.x. Kudos to plasq -- I had thought this was abandonware.
