Sorry, this info is not correct. The following URL information is not perfect. http://sr4.sakura.ne.jp/fmsound/opz.html ・Panpot, Key on/off register is same as OPM/OPP. ・Ch volume register(#0 -#7) does not exist on...

We do not have an application manual of YM2414. So, I've contact FITOM author ”madscient” to check correctly implementing of the OPZ. Do you know FITOM project? https://sites.google.com/site/fitomproject/ He said...

He said that this source contains OPZ driver that is derived from OPM and the driver can drive OPZ properly. https://github.com/madscient/FITOMApp/blob/primary/FITOMApp/OPM.cpp

He created a document about YM2414 (Tentative ver) https://sites.google.com/site/undocumentedsoundchips/yamaha/ym2414

My friend replaced a chip from YM2151 to YM2414. https://twitter.com/sdhizumi/status/1453924274989793280 YM2414 can output LR ch properly by YM2151 driver except MONO ch.

I see. Thanks.

FYI: Here is an Output Level algorithm of TX81Z(not YM2414) sound driver. https://nornand.hatenablog.com/entry/2020/11/21/201911

Did anyone test a real OPL3 board on x64 windows? Working?

Hmm... where can I download "InstallDriver.exe" for x64... My understanding, I need to run the "InstallDriver.exe" to install the driver inpoutx64.dll. Right?

However, the Dialog shows "Make sure you installed the latest OPL proxy" messages...
