Good review Larry. And he is correct, and something I failed to mention when I posted what Jamstix could do.
Jamstix has lots and lots of preset styles that you can use to make basic songs complete.
You can save these songs and use them how ever you like. Change tempo, different song. Change drummer, different sound/feel.
What can be do e with this program really is nice. I have imported Groove Monkee midi grooves into Jamstix and built a style from that. Then I use that in different songs.
It really is much more than just a drum sampler.
