Echo effect is not synchronized with actual tempo

[Uwe Klotz]

I usually adjust the time parameter of the echo effect to the 12 o'clock position to get a beat synchronized echo out effect. This doesn't seem to work correctly when pitching the playing track. The synchronization only takes the nominal tempo of the track into account, but not the actual tempo.

Currently the echo effect cannot be used for a beat synchronized echo out on tracks that are not played with their original tempo. This is a very common case when trying to match tracks with different tempos somewhere in the middle between their original tempos. For some tracks this is barely noticeable while others are producing weird double beats when activating the echo effect.

This was implemented in https://github.com/mixxxdj/mixxx/pull/1350 for 2.1. Has there been a regression?

Confirmed for both 2.1.4 as well as 2.2 :(

I compiled commit c74c08f from that pull request and indeed the issue is present there too. I guess I did not test carefully enough when working on that.
