Expected Results

playing music sheet with 6/4 time signature. Here metronome sound should be 6 times per measure precisely with tempo changes 90 to120 bpm.

Observed Results

metronome sounds somewhere 5 times in some measures ,6 times in measures(that is right), and it also sound 2times in narrow measure.

Steps to Reproduce (for bugs)

while playing music sheet having 6/4 time signature with two tempo. in the beginning(Measure 1 and Measure 2) of sheet it is playing with tempo 90 bpm. and rest of all measures (except measure 1 and 2) is playing with tempo 120 bpm.

1. select playing area in music sheet by dragging cursor from beginning of Measure 1 to the end of Measure 2.
2. after selection of Measure 1 and measure 2 click on metronome button to activate it.
3. then click on play button,
4. then tempo changes occurs before Completion of Measure 2. (here reproduce the bug)
5. At that Moment(at the time of tempo changes) previous total metronome count (Measure 1 + Measure 2) is 8. (here reproduce the bug), here total metronome count till end of Measure 2 should be 12 times.
6. i hear metronome count in Measure 1 is 6 times and in measure 2 it counts only 2 times. here it should be 6 times.
   same testing method i used in entire sheet then i found metronome sound somewhere it count 5,6(that is right), and 2 in narrow measure.

i have attached my music sheet with this bug report.

Thanks in advance !

Looks like a bug in the generation of metronome events here. The tempo change is processed first, and then the missing metronome ticks since the last event are generated. Correct would be to first generate the metronome events and then apply the tempo change.

Yes Exactly, here it will first generate the metronome events as it required and then apply tempo changes. Thanks @Danielku15 for consider it. hope i will get the latest Alphatab plugin soon with this bug fixes.
