I use Finale 2025 on a Windows 10 computer.
I have discovered a bug in the software which occurs when one has Human Playback turned on and then uses TG Tools to input tremelos. However, the problem seems to arise only if one makes a mistake and goes back and edits a measure where that tool was employed.
The problem is that when one has revised a previously input TG Tool tremelo and human playback is selected for the file, if the file is exported (e.g., to MIDI or WAV) the tremelos are silent. While I figured out the solution is to turn off Human Playback, there is no instruction to this effect in the User Guide and it is a clear defect. Hopefully it will be addressed in the upcoming Finale 2026.
