A la other DJ tools, allow djay to send out the calculated midi tempo.
Some juggling would be necessary when dealing with say, four decks, but certainly some creative solution is out there compatible with the existing djay workflow?
Especially helpful in the age of Ableton Link and hardware like the Soundbrenner Pulse.
Sync out is a priority for my workflow, but obviously some may find use for Sync in. I do think it’s a topic by itself.
