Pushed v1.19 code - The "Trim" function had been 100% broken (and crashes the program) for a very long time. Sorry for this! This happened after instruments were changed to be allocated as needed. - macOS: 48kHz is now the default audio output rate (instead of 44.1kHz) - For x86_64/amd64 users: The audio channel mixer now has higher fractional precision on mixing deltas, which is beneficial for 96kHz audio frequency mode.

Note: If you don't have libstdc++ and/or can't compile rtmidi, try running
make-linux-nomidi.sh instead.
-
- Note: If you want faster audio mixing (for SLOW devices), pass -DLERPMIX
- to the GCC command line (edit make-linux.sh/make-linux-nomidi.sh). This
- will lower the resampling interpolation quality, though...
Known issues: Audio recording (sampling) can update VERY slowly or not work at
all... I have no idea why, it works really well on Windows/maCOS.
