Protracker: notes above B-3 are not displayed but still played #24

The highest note you could play on ProTracker was B-3. But there are numerous MODs around that have been made in FastTracker which didn't have that limitation but made them unplayable on ProTracker - PT just displays ??? and chokes.

I guess you could argue it's better to replay them instead of just choking and Bassoon Tracker actually plays them like they were supposed to from a FT2 view but doesn't show any note value at all in the pattern view - it just shows the respective sample in the sample column.

In my opinion the right way to go for a modern tracker would be to play them but display a warning when saving a .MOD containing high notes.

Yep. There are also XM files that choke FastTracker - Made with Sk@le or something.

Forgot to add an example:

Technically those MODs will play fine in XM mode because it supports extended frequencies and is backwards compatible with PT effects. But BassoonTracker strips the data when loading.

So a simple solution is to just mute the bad frequencies rather than destroy them. The user can switch to XM mode to play the song properly and learn the differences between PC and Amiga mod trackers in the process :o)
