1. Mix 2 tracks with timecode vinyl. 2. Switch incoming track (deck B) to internal mode and sync. 3. Finish mix and lift needle on outgoing track(deck A). 4. Incoming track (deck B) drops by +/-30 bpm (to as low as the pitch control will allow) I think the slave (deck B) isn't becoming the master signal when the timecode is stopped on deck A. I would have expected the track on deck B to switch to master and carry on playing at the same BPM. Is this a bug? Its a great back up but a shame it doesn't work as well as it should.
