I would like to have 3 shots (as Triples) in a 4/4 bar Song wiht 165 bpm

I did the following
in Bar 6 I changed Bar settings to 3 and Tempo to -25 %
G.. G.. G/F#..
in Bar 7 I changed Bar settings to 4 and Tempo to +33 %
Em.., Em

It works - but not perfect - The shot in Bar 7 on beat 1 is not executed.

Any idea - maybe an Example how to do it ?

Welcome to the forums.

You approach is good. I've tried to force parts of a bar to play as triplets on specific measures within a style, but with little success.

Could you perhaps add the rim shot as a separate beat on a MIDI track to provide the necessary emphasis?

Only ideas, someone else might have better clues.

Thankx - i tried it - use Ochestra hit via midi,

works - but not for the whole song since the midi and the realt Tracks went totally out of sync.
Little bit frustation on my side - lots of tries - but no result.
