=== Pro Tools II TDM: 16 tracks and real-time plug-ins (1994) ===
In 1994, Pro Tools 2.5 implemented Digidesign's newly developed [[time-division multiplexing]] technology, which allowed routing of multiple digital audio streams between DSP cards. With TDM, up to four NuBus cards could be linked, obtaining a 16-track system, while multiple DSP-based plug-ins could be run simultaneously and in real-time.<ref name=":25" /> The wider bandwidth required to run the larger number of tracks was achieved with a [[SCSI]] expansion card developed by Grey Matter Response, called System Accelerator.{{sfn|Collins|2002|p=10}}
