I only just found out about the panpot positioning being reversed on the MT-32/CM-32L/CM-64 until now.
However, why did Roland never fix this issue on the CM-32L which was released in 1989? The Roland D-110 which was released in 1988 doesn't have this reversed panpot (it appears Cloudschatze had his reversed). I've actually tested this as according to the D-110's manual, the first 2 bass drums should be at 2>, which as you can probably tell means slightly to the right. With the audio cables inserted correctly, the panpot was slightly to the right - I also tested it with a sustained channel by setting channel 2 to 7> and playing a few notes through it. Yes, it was completely to the right
I've posted several samples from the 1.10 D-110 (the last revision) over at Alistair's forum
. Not only is the panpot in their correct positions, but there is actually some tone differences compared to the recordings Cloudschatze did. The slap bass is much different for a start (listen to Chi Chi Bar 1 and the introduction) and the poly doesn't seem to drop as much - or hardly at all - on Space Quest 3's introduction. So if Cloudschatze did have his cables plugged in correctly
, it would mean Roland fixed this issue after ROM version 1.06.
Just to double check it wasn't the software I was using, I manually changed the panpot on the module it's self. Again, the positioning was correct either at <7, >< (center) or 7>.
I really don't understand why Roland never fixed this. It's obvious they could have since the CM-32L was released a year after the D-110 was
