Hi all!

I wanted to share a DOS mixer I created for the Orpheus II sound card.
It's called OP2MIX.COM, and it allows you to see and change the current volume levels, turn SRS on or off, and see the current configuration of the card.
OP2MIX is an Orpheus II mixer, not an initialization program. To switch between modes (SB, OPL3/CrystalFM, WSS, etc.), you'll still need to run ORPHINIT.

And just a quick disclaimer: OP2MIX is provided as-is, so use it at your own risk. I’m not responsible for any damage or unexpected behavior that may result from using it.

I guess it depends if you are making a front end for the ini file or trying to make a more convenient mixer overall, you'd probably want to have the minimum values consistently on the left and the maximum values consistently on the right (e.g. Range 0-7 instead of Range 7-0), and where the maximum volume is the lowest value of the range, invert the range so it matches the same pattern. Just thinking out loud.

Yeah, the idea is more to make a convenient mixer for the card rather than a front end for the INI file. I originally started it because I wanted an easy way to see and change the current volume levels without having to deal with the INI file, and it grew from there. It has command-line options to change the volume levels directly, it's not a front end.

About the ranges, I see what you mean. Something looked odd to me from the beginning, but I couldn't quite figure out what it was. Thanks!

(Screenshots updated to reflect Min-Max volumes) Thanks!
