Actually it is the Blues MIDI pack that I have. In my opinion the songs and sequences are basic Blues type, say for doing Chicago Blues type tunes. I have a lot of the SDX’s and a some EZX and MIDI packs. I use the 12/8 type rhythm on a lot of tunes not strictly Blues, and some Jazzy type Blues stuff. Frequently, amongst all the SDX’s, EZX’s and MIDI packs I have, I don’t find what I want. So In my opinion, there is a lot of room for improvement…
