Bug Description

Mixxx should provide a visual guidance for the downbeats of a track. The downbeat is the first beat in a bar, often a bass note, and is important when mixing. It is critical to know when the music is playing a downbeat and when it is not. You can hear it when cueing a track, but it requires some experience with beatmatching.

Currently, Mixxx differs not between the various beat in a bar, all beat marker look the same which makes mixing by looking at the waveform harder then with other programs.

This is a great feature that can also be extended to phrases (i.e different lines for every 4th and 32th beat). Is there any way to merge the code change that looks already available?

The old merge request linked above was never completed and is outdated.

Yes, I tried merging the change into the latest code base and it seems broken. There is a problem with the isFirstBeat() method, I will try to fix it.

Sample of the first successful grid with first beat emphasis attached. It would be nice to have some guidelines how all the beat grid elements (beats, cues, loop markers, etc.) are supposed to be laid out, because there are cases when they overlap each other.

Feel free to draft one on our wiki.

Take 2 on the measure/phrase markers, finally managed to find a position that is not overlapped by hotcues and loop markers. Measure markers are the same color as the grid lines and the phrase markers are hard-coded as red for now. Will try to add measure size/phrase size and phrase marker color as part of the skin. Reading measure size/phrase size turned out to be a lot of work and is probably not worth it.
