Self-explanatory. No special features observed with patch characteristics so far.

Bank conversion in progress. Turns out this uses 4-op mode. Won't sound right for the most part without 4-op mode implemented.

Patch tests partially working, but percussion needs to be investigated further due to use of rhythm mode. Looking at whether some form of rudimentary conversion to standard 2op patch is possible. Also some 4op patches on transcoding to compatible format, some presets not correctly output. To be verified.

Seems my understanding of the xx-AM modes was flawed, so now with 4op patches they will always map the secondary pair 3 voices ahead. This fixes certain patches, however there are still some remaining issues with behaviours..
