Oh I missed the tracker days growing up, I had to manually program my commodore 64 (did not have an app) to make sounds/music (if you would call it that). I started dabbling in making music in the mid 90's starting with samples and Acid 1.0 as well as Rebirth <3 and then the progression to that; Reason. I never heard of Renoise will have to try it out. Maybe the old tracker format would be better than drawing notes on a piano roll. Sony really jacked up Acid since they bought sonic foundry (they made great apps back in the day). So for a DAW I have been using Reaper which I like for its never ending full feature "demo" mode.
