I've got a newb question. I just discovered VGMPlay tonight, and built it on my macbook. I'm experimenting on "01. Ultima Theme" at /packs/pack/ultima-v-warriors-of-destiny-apple-ii, which is for Mockingboard A (4xAY-3-8913) x2.
I'm attempting to create a .wav with all but the first channel muted. The song sounds like it only uses 6 voices, so I tried modifying the VGMPlay.ini file with:
1)
MuteMask = 0x3E
2)
MuteMask = 0xFE
3)
MuteCh0 = False
MuteCh1 = True
MuteCh2 = True
MuteCh3 = True
MuteCh4 = True
MuteCh5 = True
but none of these settings muted any of the channels. Suggestions?

Technical discussion about the VGM format, and all the software you need to handle VGM files.

At least, I need to explain what "4x AY-3-8913" actually means. It means that the actual VGM contains:
Now I'm afraid you encountered the main drawback of VGMPlay compared to the Winamp/foobar plugins - the settings always apply to all instances of a sound chip.
So if you have 2x AY8910 and you do "MuteCh0 = True", you actually mute 2 channels: The first channel of each of the AY sound chips.
Also I just noticed, that I forgot to add configuration settings to allow muting the YM2203's SSG channels. So you can't mute those separately in VGMPlay at all. :/
I'm afraid your only chance right now is to use one of the VGM plugins for Winamp or foobar. I know that in_vgm lets you mute everything separately.
Or if you are fine with programming, you could also hardcode the muting settings at this spot:
- 2x AY8910 (variant AY-3-8913)
- 2x YM2203 (each YM2203 includes all AY8910 features, that part is often called "SSG")

Code: Select all
ChipOpts[0x00].AY8910.ChnMute1 = 0xFE; // mute all but 1st channel on first AY8910
ChipOpts[0x01].AY8910.ChnMute1 = 0xFF; // mute all channels on second AY8910
ChipOpts[0x00].YM2203.ChnMute3 = 0xFF; // mute all channels on first YM2203's AY8910
ChipOpts[0x01].YM2203.ChnMute3 = 0xFF; // mute all channels on second YM2203's AY8910
