Thank you Jo22. I will look at it. If there will be something interesting and leaving questions, I return to this thread.
Edit: these documentations are very thin. There are no word about CSM. You can only read CSM means "Composite Speech synthesis", register 08, bit 0x80. No more... My question is still valid.
I have old detailed documentation for YM3812 (OPL2) including attack and decay tables, explaining what 3db/octave means with table but the CSM/CSW is also not described.
To Administrator: please add this documentation as attachment. I have blocked attachments more than 5MB. It is very detailed spec for Yamaha YM3812. It will useful for more users but it on the verge of being forgotten. Each newer version is shorten. Ufile.io deletes files after 30 days.
