I bought AFT when i first started. I haven't used it in months. I've migrated to a program called "Band in a Box". It has some tremendous improv and ear training tools. The two features I like is the chord progressions and the style maker. First, you can enter a chord progression, and choose a style and you will get a track that adds drums, piano, guitar and sax! Or you can select a song style and let it create the bass part for you. After you work through the song, you can mute the bass and create your own part. Once you are satisfied, you can record your part and make it a part of the song!
This works for me, because once I create somthing I like, I drag it into Ableton Live to polish it up. It takes me directions I may not have thought of on my own. Also, because the program has matured, there are alot of songs that match the various "gospel feels" I like, as well as having transposition on demand. I could go on and on. Its just that good. Have fun with AFT!
