I have EZDrummer 2 and a couple of EZX sound packs. However, I can’t seem to find out what overlap there is in MIDI material between the sound packs and the MIDI packs. For instance, the Blues packs seem to indicate they are the same. I simply want to know if I need to buy, say, the Jazz MIDI pack in order to get more or if it’s the same material as in the sound pack. Also, it would be good to know more details about what’s in the MIDI packs.
