G4 400 OS 9.2 w/ opcode 2.3.8 plus midiman usb "midisport 4x4." Running Logic 4.81. Midi is so shit (skipping and sluggish, like writing its own track!) its not even funny. Anyone have success with this midisport 4x4 on mac?? I think I've tried "everything." I think Midiman might be stupid useless on Mac. Have you succeeded here? Perhaps OSX will solve this problem (can't get worse). But I'm not ready for X. Any ideas?
