date: Thu Nov 19 16:10:48 EST 2020
Pushed v1.41 code - Code refactoring and code cleanup - Fixed minor BPM duration issues when rendering song to WAV - Fixed some mouse problems in fullscreen mode on multi-monitor setups - Bugfix: Properly change pattern length after loading .xp pattern files (FT2 doesn't do this, but I think this makes sense!)
