track out of sync after overview seek, quantisation on.

[Daniel Schürmann]

If you enable quantisation,you can start a track in sync with a playing track.
If you now seek the track with there is always the same small offset (double base) between both tracks.
If I disable quantisation I get a random offset as expected.

It would be also cool, if we not just sync the beat but also the bar.
How about using a n x beatjump length?

I couldn't reproduce this.
I loaded 2 tracks with quantization enabled and tempo synced (but not locked), and moved around both tracks using the overview panel : beats stayed synced throughout.

There's though an issue with effects using quantization (Echo, Tremolo), which are getting out of sync when moving manually through a track.

Anyway, being able to move by a multiple of n beats (4 seems right, maybe 8) could be useful to stay rhythmically synced.

My bad, there's indeed a small offset after moving around

I suspect that fixing this will require risky changes to how quantization and track transport are handled, so I'm retargeting this to 2.2.

Interestingly I cannot confirm this with Mixxx 2.1.5.
@Johan: are you able to reproduce this with this version?
