No, not at all. I just find the C8 is more responsive with the direct USB connection (more like an ethernet controller a la Control 24) rather than MIDI controller via a MIDI interface. I actually use the C8 for Pro Tools and the MCU for Digital Performer (in another mode - easy to change back to HUI protocol). The faders are nice, very light feeling. Great little controller. More expensive than the C8 I belive (not by much though).
