+;Number of channels
+:By design the number of channels is supposed to be the same as that of the referenced SNDDs (this implies that all the SNDDs in a group are supposed to have the same channel count).
+:If for whatever reason the channel counts in OSGr and SNDD are ''not'' consistent, then the behaviour depends on whether the OSGr is referenced from an OSIm or from an OSAm:
+:*the channel count in an OSAm's OSGr determines the channel count of the decompressed sound buffer, therefore mono SNDDs will sound 2x higher/faster if the channel count in their OSGr is set to 2, and stereo SNDDs (e.g., music) will sound 2x lower/slower if the channel count in their OSGr is set to 1.
+:*the channel count in an OSIm's OSGr seems to have no effect if the SNDDs are mono, i.e. setting the OSGr's channel count to 2 does not result in a higher pitch. As for stereo SNDDs, apparently they cannot be used in an OSIm's OSGr at all.
 ;Fury vocalizations
 :Those are sped up by 1.14 in Oni, which explains why they sound weird when exported.
