Yes, the way she syncs things (and the only way that is possible to sync loopers) is by using Midi.

Music Instrument Digital Interface is a standard digital mode of communication between digital
gear (and analogue gear that has been retrofitted)

If you want to understand this world it is very important to understand , at least cursorily, how this language works, practically speaking.

MIDI has 16 possible channels and both units must be set to the same MIDI channel (unless both are in OMNI mode)
to 'talk' to each other.

I highly recommend that you spend a bit of time and at least go to the wikipedia MIDI page so you can figure out how to start syncing your music.

essentially, though, you must use a hardware looper that has MIDI send and return and a midi software looper equipped with the same.

The Repeater, the Lexicon Jamman, the Gibson Echoplex EDP, the Looperlative all have MIDI sync capablities.
There are others too, but I don't own them so you should look up each respective looper to let you know whether they have
such capabilties.

Additionally, your PC desktop or laptop computer must have come kind of MIDI input and output capabilities. Standard computers
do NOT have MIDI capability but there are a plethora of inexpensive solutions to add that capability to your computer, for as little as $30 or $40 bucks (if not cheaper).

Any decent sound card worth it's salt will have MIDI capabilities and you have to have such a card in order to put live musicall
input into your computers particular Looping software (Ableton's LIVE, Mobius, Sooper Looper, Max/MSP, Augustus Loop, ,etc.)
