The 9Pin/MMC Interface from JLCooper connects popular hard disk recorders from Tascam, Mackie, Fostex, Roland and many computer-based audio editing systems to a standard video edit controller or switcher for automated audio-follows-video control.
The unit interprets standard RS-422/P2 protocol messages and changes them to MIDI Machine Control (MMC) messages. This conversion process allows recorders and editing systems to be controlled by video editing systems that originally controlled professional video tape recorders and DDRs.
