Renoise is a Digital Audio Workstation (DAW) based on the tracker paradigm. I've been using it since nearly 2 decades, I can't say enough good things about it. It takes a while to get into, and I had a head start with playing around with trackers since the Amiga days, but once you *are* used to it and know a lot of keyboard shortcuts, it's bliss.
Software I can recommend, mostly free and open source.
