Shame on Toontrack…? Not at all. It’s absolutely impossible to use a mic setup from one library in another. And least of all, between an EZDrummer library and an SDX library. You just must understand that each library has been carefully prepared and recorded by a sound engineer in a real studio. He has set up his choice of REAL microphones, and each time a sample has been recorded (one single hit on the snare, the kick, or the hi-hat) has been captured by the original mic and other mics, so that, for instance, you can hear the same sound from different sources: the direct mic, or mics (sometimes you can have two different mics on a kick or snare – in and out and top and bottom, as well as the overhead, room mics, and in the case of SD3 libraries, you also get to control the level of the bleed that went into other kit piece’s mics. – If you read the description of the SDX libraries, you may be surprised to find out that in some of them, there are less mics than in others, and you can read even which mic model has been used for each kit piece, overheads and room mics. ¡And they are completely different from the mics used in other libraries!. Some libraries for instance, only use one mic on a tom. Others use two: one on top and one below, so you can set your own sound to taste by mixing both sources. In the case of SD3, besides, within the mixer you can set up buses where, for instance, top and bottom snare mics are mixed. You can have that kind of bus in one library, whereas other libraries use a different setup. The only changes you can make are within ONE library, because all of the kit pieces have been recorded with the same mic setup. You can do without one of them if doesn’t suit your needs – for instance, SD3 library includes surround mics. If your recording is not going to be “surround” but plain stereo, you can do without those.

To sum up: The mics used in the recording of the samples can’t be swapped from one library to another because each library consists samples recorded with different mics in a different setup within a real studio room. All the mics capture the sound at the same time and the sound from each one is saved as a different sample. What you get in a library, you cannot use in another. Period.

Of course, you could always export all of the different tracks in a song recorded with one EZDrummer kit, and then play the same MIDI though a SD3 kit, and mix the individual tracks in your DAW to taste. It would work well if you used only kit pieces mic sounds (without any bleed). But the moment you work with the overheads, or room mics where the sound of the drumkit is recorded “all at once”, you’d have tracks with different sounds!
