Well yeah, from my experience MMD0 and MMD1 files play rather well, while MMD2+ files don't...
High octaves are not played correctly.
Thanks for the test cases. I suppose the exact behaviour here might depend on the software mixing flag, as I guess the additional octave only work "as intended" when that flag is set?
Re "Not really a new issue": MED/OctaMED support has been spotty since the early days of ModPlug Plugin/Player/Tracker. I clearly remember doing some mail correspondence with Olivier back in the 90s, and he did some minor changes based on my feedback to improve the MED playback somewhat, but in my experience MP has never been a good platform for playing back MED/OctaMED modules.
I'd be happy support any effort to improve this. I used an Amiga in the period 1991-97, and made a number of MEDs using MED 3.00, OctaMED 3/4/5 and SoundStudio 1 during this time, including multichannel stuff. I still have most of my stuff from this period, as well as some other MED stuff I know have issues in OpenMPT.
One key issue is timing. OctaMED has a number of different parameters that affects speed, including:
Some other issues I have noted:
At the moment there is sadly not much you could help with - I have started working on a new loader a long time ago but the MED format is so (unnecessarily) complex that it's not exactly fun to work on this feature. I'd say about half of the new loader is done, probably - which means there is still a lot of work to do. It might happen in OpenMPT 1.29 if we are very lucky, or OpenMPT 1.30 - but no promises.
Once the loader is done, expertise from OctaMED users will of course be useful for testing the new code.
