a821 [1] filed a deletion request for protrekkr-git [2]:
Abandoned project and I have requested deletion for two of its
dependencies (sporth and soundpipe). Below I quote the former
maintainer's single comment:
Note that PaulBatchelor lists his Protrekkr fork as abandoned, and
this package does not seem to work properly anymore. Source:
http://pbat.ch/proj
For anyone wanting to adopt this, falkTX's protrekkr fork might still
work https://github.com/falkTX/protrekkr
For end-users looking for an OSS music editor/tracker, I recommend
looking into radium, which is actively developed.
