Help with Volume!

How do I set Wave sound volume less than MIDI volume? When I choose to play a song with just one hand, the notes for the other hand are tremendously louder. I set my speaker volume all the way to zero. I'm not sure if that controlling the Wave sound.

We have 2 ways to get sounds with our program:
1. From computer
2. From piano

I recommend to tune your system to have the sounds coming from piano.

Please, go to all programs - tools - tuning - sound play back

There will be 2 windows: for computer and computer + piano games

Check the second window (click on drop down menu)

How many options do you have? Click on different option. Open Gentle piano again and click S to hear, where the sounds coming from.

Let me know, how it goes!

In case anyone else has an old computer with Windows XP (like me ) and didn't manage to find it that way, I changed it like this:

C / Program files / Doremifasoft / Soft Mozart 2_6 / Soft Mozart Tuning / Midi playback for computer + piano

And there I chose the option which wasn't selected before.

Yes, this is the screen that appears for changing sounds play back:
1. The list of options for computer games
2. The list of options for the computer + piano games
3. The option for the people, who doesn't have pianos, but MIDI controllers.
