peter When you want the click to start immediately, you need to turn of the fade out. As long as the fade out is still playing, the click will not start in "Stop" mode as playback is not yet stopped.
All Audio fade settings are off, the timing gets worse the slower the beat , pick a song with tempo set around 70 , in Metronome set it to STOP and visual only, now play the song and keep the beat , hit stop and keep the beat, you will notice as the visual metronome kicks in its way out with your count.
This trows your timing out initially, you can sort of fudge it to get on beat so you can be in sync but its not ideal , specially with slower songs.
It would be nice if every stop and start immediately triggers the visual click , and if possible every audio segment start to do the same , that way the visual click would be in time for most of the song no matter where you stop and start or how long a song is that has slightly varying tempo.
If you stop and start on the same spot the visual sync would be always perfect if you play through a long song every time a start of audio segment begins the visual click restarts so the click would never drift off by a noticeable amount.
Just a thought , i don't know if its a possible solution , but the stop start delayed sync is definitely a problem.
