Is there a location on this site to talk about music 'stuff' other than guitars and amps?

If not (or so), one I recommend is Band in a Box by PG Music. It allows you to create chord progressions in just about any genre of music, with several sub-styles to choose from. Many of the styles include 'real' instruments... in other words, a real sax player, drum player, etc., recorded the riffs, runs, etc., which then get incorporated into your song composition. There also are chord building functions, lessons, ear training, you name it. A very diverse product that offers an incredible amount for the home player. I have several songs listed on my profile, which uses this program. I certainly don't use it to its fullest capacity, but it gets the job done rather well.
