Hi, I have Finale 2016, and I have a piece that starts with quarter note = 96 for the first 12 measures, then the easy bossa drum groove begins (which is preset I believe to quarter note = 120) and plays along with the rest of the piece. I would like to override the 120 with 118 using a tempo marking in expressions. When I do this the playback after bar 13 is much slower. Even slower than the initial 96. Is there a way to correct this. 

Basically I want m.m. 1-12 to playback at quarter note = 96; then m. m. 13-147 to playback at quarter note = 118 (with the drum groove). Is there a simple way to do this. 

Thanks,

jeb
