Plus they make both Macintosh, iPhone apps & Windows software. Thing I like about them is for one, they are local & also their products are 1 of a kind that I haven't found comparable stuff from any other software maker.
I bought their guitar program & the thing works great & for bonus it was cheap. I think like $18 bucks or so. can't beat that.
If you have a computer & are looking for some really cool novel & useful software I'd at least check their web site out.
