I am a guitar teacher and want to get some software I can use to make some 'jam tracks' with which students can explore soloing. I'm not looking for anything fancy, just a simple background, a little rock group or blues combo. Though I have an lexicon Alpha whatever you call this unit for inputting music into my computer, and a modest EV mike (I paid about $110 for it), I am not so interested in recording as I am in patching something together. Years ago I owned a Boss DR-770 Drum machine and that really had the features I wanted, with built in patches of sound in a variety of styles, and all the elements could be modified to my liking. I've been looking at programs like Sony Acid, Cakewalk Music Creator and they seem more geared to recording than patching. I don't have a lot of money to sink into this project and can't afford to buy extra sound loops. Can anybody suggest a modestly priced program that will do what I want? I'm really unfamiliar with music software other than notation software. Thanks.
