I hooked up the Minitaur to my iMac i7 and have been using Live 8 as a test bed.
One observation so far is that, if I use USB MIDI, as soon as I connect that cable, I get an appreciable amount of digital noise. I can actually see the noise floor on the channel level meters in Ableton Live.
My set up is MOTU 828 Mk3 (latest drivers) connected via USB to an iMac i7.
Any suggestions appreciated.
