I've updated Federico Ferri's [tracker] external to be compatible with the current pd api (and to use pd-lib-builder hopefully)

also available on deken for windows, macOS, and linux (search "tracker")

tracker is a simple gui object that allows rows of numbers to be addressed https://en.wikipedia.org/wiki/Music_tracker

if compiling on a system other than osx one of the backslashes before the n (newline) on line 20 of tk2c.bash might need to be removed currently.. I'm not great at make either..
