Hi guys,
as far you know for example the unpatched Roland SCB-55 REV 00 or SCB-7 cards have reversed L/R channel outputs. The quick test to them is in Doom 1 game E1L1. When the first riff comes from the right channel the channel order is correct.
Could anybody tell me how to confirm the channel order for LA32 based devices?

Thank you.

User manuals clearly say that the channel order is reversed compared to General MIDI.

Interestingly, D-20 and D-110 have same channel order as General MIDI does.
