==Approaches==
  * Provide mixed down kits online which just output on the first two channels
  * Create an own plugin which is super simple and has only two outputs

The first approach currently seems more promising.

**Maybe this whole thing is just a stupid idea...**

Marking stereo pairs in the channel maps in the xml would be useful for automatic stereo downmixing.

Stereo downmix toggle button in the UI?
  * Drumkit file channel map has stereo channels marked with either left or right.
  * When active only the first two plugin output channels are used and marked stereo instrument channels are mapped to either output ch1 or ch2, the rest are mapped to both.
