You might try clearing MIDI data. Sometimes, things just seem to sneak in. Select the score > right click > Clear Selected Items...  In the next frame, select only the MIDI data (upper right) and OK.

Nekogash tempoto e potrebno  da  se  menuva ..  Na  primer ... Od 1 tak pa  do 30 ili  bilo  koj ..  edna  chetvrtina  nota = 45 .. A  od  41 takt  e  potrebno chetvrtinata nota =  96  ili bilo  kolku ..  Jas  ne  mozev  da  go  storam  toa ..  Bilo  kako  da  smenev ..  ostanuva  na  edna  ili  druga brzina  (  45  ili  96 )  Od   prv  takt pa   se  do  kraj ..

from Google Translate, Lazo says:

Sometimes the tempo needs to be changed .. For example ... From 1 beat to 30 or any .. one quarter note = 45 .. And from 41 bars it takes one quarter note = 96 or whatever .. I can't to do it .. No matter how I change .. stays at one or another speed (45 or 96) From the first bar to the end ..

Lazo,

If you are trying to change tempo via the small tempo box at the top right of your screen, that is not designed to do what you want: you should try to use the Playback tab of the Expression Tool to create your various tempo settings.

Again, via Google Translate:

Ako pokušavate promijeniti tempo kroz mali tempo okvir u gornjem desnom kutu zaslona, koji nije dizajniran za ono što želite: pokušajte koristiti karticu Reprodukcija na Alatu za izradu da biste stvorili različite tempo postavke.

In playback it starts at the correct tempo, but after 15 measures it speeds up. Any suggestions? Thank you.

1. Delete Selected Items > MIDI Data

2. Export as XML, reimport

That solved the problem, (using method 1.) Thanks Mike.

Is there a window where you can see all the MIDI data?

Not in Finale itself (IIRC), although you could export the MIDI data and open it in another program (such as some DAW's or a MIDI sequencer/editor).

Thank you for the information.

Seems strange that such a detailed and elaborate program such as Finale, wouldn't have that feature. It would make life easier, rather than have to export a file to another program for editing, then bring it back to Finale.

There are always little things that individuals feel would make life easier for them. Finale cannot add every one of them, but you can post a request for the option on the Feature Request Forum

https://makemusic.zendesk.com/hc/en-us/community/topics/200449177-Finale-Feature-Requests?sort_by=recent_activity 

and see if the idea has any support.

Fair enough. Thank you for your help.

Could you possibly help me with another problem?

When I'm finished working with Finale and shut it down, none of my other music files and videos will play. The only solution I have found is to restart my PC. Then the files will play. I have a PC i7 with windows 10. Hopefully there is a better solution than having to restart the computer every time I use Finale.

Regards,

Boris
