Typing apt-cache search liblo gives this on my Bela Gem stereo:
liblocale-gettext-perl - module using libc functions for internationalization in Perl
liblockfile-bin - support binaries for and cli utilities based on liblockfile
perl - Larry Wall's Practical Extraction and Report Language
while on my laptop (Debian 13), I get liblo7 - Lightweight OSC library. So, is liblo not available in Bela's repositories? Should I build from source?
