Thanks although I got a message that says:
"the selected file is not a supported input plugin"
That said, if I add the contents of the vgmstream zip I downloaded to the music bee plugins folder in Program Files, I do see an entry for vgmstream in the input plugins list in the "Player" preferences. However, if I try to play a .kvs audio file, I get an an error that says:
"unable to open file (error=BASS_ERROR_UNKNOWN)
I tried downloading the bass_vgmstream.dll file from the post above but still getting the same error.
If you're trying the Winamp input method, do NOT rename the plugin, keep it as "in_vgmstream.dll" and load it via the "Import Winamp" button in the "Input Plugins" section of Prefs/Player. Here is what I make out of the instructions of using that plugin--what I would try, although it's up to YOU to do that! :
1. Download the primary/support files package here:
https://github.com/vgmstream/vgmstream-releases/releases/download/nightly/vgmstream-win.zip.
2. Extract the entire contents of the zip into a folder named "in_vgmstream" and place that folder inside the main MusicBee directory (the one containing MusicBee.exe).
3. Open MusicBee, and using the "Import Winamp" button in the "Input Plugins" section of Prefs/Player browse to and select the "in_vgmstream.dll" file.
4. Hit the "Save" button, and restart MusicBee. Then try to play a vgm file.
And how I would go about trying the BASS method INSTEAD OF the above Winamp method:
1. Download "bass_vgmstream.dll" from here:
https://github.com/X-Hax/sadx-mod-loader/blob/master/extlib/bass/bass_vgmstream.dll , and place it directly into the MusicBee main folder with the other Bass dll's.
2. Download the support package here:
http://hcs64.com/files/vgmstream_external_dlls.zip; from it unzip these 3 files also directly into the MusicBee main folder with the Bass file: libg7221_decode.dll, libmpg123-0.dll and libvorbis.dll.
3. Restart MusicBee, and try to play a vgm file.
Next step is after trying one or both of these methods (I would try the BASS method first), POST BACK and tell us if it worked!!! Good luck!
