Toontracks EZ Player Pro makes it real easy to use one drum sampler with other midi. You just open up EZ Player and the sampler you want to use, say Abbey Road 70's. You set a few things the way you want, choose the "map wrap" and done in 20 seconds. I have all my midi in EZ PLayer and I can use "Odd Grooves" midi with Superior Drummer or Abbey Rd 50's midi with EZ Drummer 2. If I recall you had to contact AD and ask for a copy of the midi you own to put it somewhere else because you can't find it in any of the AD programs folders. AD is the only one that takes any effort to import into EZ Player. Everything else you just drag them in. I even made a "Styles" Library where I have,say, Indie and then all the Indie midi I have is in one place instead of bouncing around to build an Indie track. If you use EZ Player, everything in your EZP browser will show up in your EZ Drummer2 browser.

I use project templates with EZ Player and diff drum samplers so it's just there when I start a project. I hope this was not off topic just more detail.
