macOS 26.4
Vivaldi running BBMO v2.0.7 beta
BBM 1.66c
I made a couple of songs in the BBMO and then converted them for the BBM.
The BPM were 105 and 88. In the BBM they both showed up at 60BPM and I could not correct the tempo in the BBM.
To troubleshoot, I exported the two songs from BBMO to MIDI and when I opened them in my DAW, they were 60BPM. I adjusted the BPMs to 105 and 88, saved as MIDI from my DAW and then added them back to the BBM. They played correctly this time.
This happened for 1 out of every 6 songs I worked on.
