In a nutshell, included in each mixes and stems pack are the relevant mix and stems
files for the Drum Kit. The mix files are full mixes of the drum kit, once it has been through
the mixing process, using such processing as EQ and compression. The
stem files are sub mixes of the kit that will have the same sound as the
full mix files. Where the full mix files will be mixes of the whole kit,
the stems files will break the kit down a little into say a file for the kick
drum, another file for the snare drum, another file for the rest of the kit
and then finally yet another file for the room mics.
These individual stem files of the kit can then be played back together,
giving the same sound as the full mix files, but also giving you a bit
more control over the separate elements of the kit.
This is a great option for anybody who wants an immediate sounding
kit, but still wants the flexibility to change the sounds or levels of the kit
themselves.
These are then be saved in a multichannel format,
so one file with all the separate tracks in.
For those that just want stereo drums they will choose Stereo instead of Multichannel in the Drum Picker.
