Clockworks is used for cable routing (like a MIDI patchbay), as well as other settings such as pedal settings, sync settings, etc. If you only plan to use your interface with a MIDI sequencer, the sequncer will handle all routings and no changes should be made to your interface's default routings. Any changes you do make would interfere with your sequencer's ability to use the interface for MIDI I/O.

The following interfaces are compatible with Clockworks (assuming there are compatible drivers for that interface in the OS you're running)... Digital Timepiece, MTP II, MTP AV, Express XT, Micro Express. The following interfaces are not compatible with Clockworks. If you have these interfaces you don't need to install clockworks on your computer... Fastlane, Pocket Express, Express 128, Micro Lite.
