I tested the problem extensively and concluded that there are two separate issues:
- One of the two players randomly lags for a splitsecond if the motor is running. This obviously causes two songs that ran parallel to not be in sync with each other anymore and ruins a show. This issues is not fixed by switching the platters and stays in the same player regardless of the platter that is mounted.
- Both players have problems with the BPM analysis or playback: If you set two songs analyzed on the players to the same tempo (set the ±4% range for the pitch fader and choose the lowest pitch fader position for which the tempo switches to a chosen bpm value) the actual tempo is way off sometimes (about 2 bpm) and the songs run away from each other quickly. The BPM does not seem to be constant though since I’m not able to find a tempo for which the songs play in the same speed even though I can beatmatch actual vinyl well. This issue could not be reproduced with motors turned of so far.
I’m on the verge of returning the players since it really is no fun playing this way. It makes me really sad though since I loved the options they bring. But these issues really are absolute deal-breakers. I found a few posts on this forum that seem to match the second issue but barely any with the first.
I also tried downgrading Engine OS from 1.6.1 to 1.5.3 but that did not fix any issues neither did a factory reset or a platter swap/reassemble. Any other ideas?
