Should the order of channels within a group (which mustn't have gaps) just match the ACN order? This is different from FuMa. e.g. directly substituting names gets you something like: AmbisonicBH1P1Group "Ambisonic B stream of horizontal order 1 and peripheral order 1." 0: ACN0 (formerly w) 1: ACN3 (formerly x) 2: ACN1 (formerly y) 3: ACN2 (formerly z) Should this be: 0: ACN0 1: ACN1 2: ACN2 3: ACN3 (No gaps in this case, but H2P0 has channels(*) 0 3 1 8 4, so I'm asking...)
