The PPS-2 is a MIDI-era Synchroniser by JL Cooper. Using frequency-shift keying, it can convert MIDI clock and song position pointer events, and even MIDI time code events, into audible waveforms and back again. You can therefore use it to "stripe" a single track on a multitrack tape with the song's tempo and exactly where in the song you're up to at any given time. When playing the tape back, the MIDI sequencer can stay perfectly in sync with the recorded material.

This lets you continue evolving the composition even after you've started tentatively recording a few tracks, something we take for granted with modern DAWs. Synchronising a multitrack recorder and MIDI sequencer was very much the precursor to the modern integrated studio.

Tips

The MIDI out port seems to act like a MIDI through port as well. To avoid a MIDI feedback loop, only plug in the MIDI in cable when first striping a tape, not while playing the recorded clock signal back.
