PostConform v2.0 requires either a Digidesign Universal Slave Driver or an LTC-to-MTC converter for synchronization. USD: Universal Slave Driver connects directly to Pro Tools|24 MIX and MIXplus systems, but requires a qualified modem-to-serial converter for use with Pro Tools III systems in Blue & White G3 / G4 configurations. NOTE: PostConform v2.0 is currently not supported with Pro Tools III systems. A fix for this is currently under development.LTC-to-MTC Converters: Digidesign recommends using a serial MIDI Interface.
