About Logic Pro TDM Support

Logic Pro provides access to many of the TDM functions supported by Pro Tools HD systems. Time Division Multiplexing (TDM) is the time-interlaced transmission of multiple digital audio signals (or streams) through a single data bus. This bus system is physically isolated from the computer system bus, and runs between individual TDM-capable cards. Up to 512 digital audio channels, each with 24-bit resolution, can be transmitted on the TDM bus. These streams form signal paths within a virtual mixer. These signal paths are necessary for the insertion of plug-ins, which are calculated on the DSP hardware, and routed into the individual channels, or are selected through auxiliary busses.
