So I've been working on a new music creation software at work. Its called PROGRESSION. It allows you to write or play in tab/notation and create full tracks with a host of instruments. It includes an amp simulator and articulations to make the tracks sound realistic. Its an exciting program and it's easy to use.
Check out some of the demos and let me know what you think.
