This space-age wild-blue-yonder GUI was a stumbling departure from MOTU's signature Jackson Pollack aesthetic. MachFive 1.05 will not show in either Cubase VST 4 or 5. It runs in Logic 4.7 but will not preserve settings when saved with song. It does, however, preserve with Logic 6.3.4. You can run this simultaneously on more than one computer, as the Ilok is only required on launch. This would not be my first choice in the (ease of use) performance category, i.e. clumsy keymapping, as compared to Kontakt. In terms of sheer efficiency, Unity DS-1 (likewise not fun keymapping) in 32-bit mode with it's system level engine, 32 sample buffer and ability to run soley on the 2nd processor would outfly this dirigible. With OSX on the horizon, the heat was on for MOTU to have a broader appeal. A MOTU exec told me that no one would have left OS9 if it were not for the pressure and agenda of Apple to do so.
