I simply can't figure it out. I thought it was impossible, and my only choice would be getting a mod wheel, but it turned out I was wrong. I read the following in the GPO Studio help file -
You will be able to achieve the best results by using the GPO Studio "Default" mode, if you are proficient in Finale. The default mode requires for you to set mod wheel values in your score, so that you can hear proper volumes. You can do this by using Finale's Expression Tool to create and insert expressions with mod wheel values. Please refer to your Finale manual for details on the expression tool.
...but how? This makes it sound so simple. You put the expressions in, and it works. But the problem is, it doesn't work. In fact, the only instrument where I heard any difference when using the expression tool was the piano.
I did a search for help on this forum. I didn't understand anything.
Does anybody have any suggestions?
