The point of using 900 BPM is to remove all volumetric and pitch instrumentations (and waveform in certain channels) so that people will not get mad just because a Game Over fanfare uses more than 16 instruments.
If I instrumentate a volume E version and a volume D version of instrument 09, as well as instrumentate an S02 version of instrument 04 (which I should), or simply instrumentate all Sxx variations, then it has to exceed 16.
I know this isn't documented anywhere but 900BPM is the max speed and famitracker will not skip rows if you try to use a faster speed (which means the BPM value is inaccurate for BPMs over 900). It could easily be added, but you already have full control at 900BPM so it would only waste CPU time and increase complexity.
You will find that it the attached module. Sometimes nothing is played, i.e. the note is skipped; Sometimes the note will last forever, i.e. the note cut is skipped.
Then I test it in 102Hz, and indeed everything plays well.
