Adjusting the volume with the mouse sometimes cannot be adjusted accurately.

こちら、どうなりましたか？

This is a feature request. I hope that I can use the keyboard's arrow keys to adjust the volume accurately, or manually enter the volume value.

Masterボリュームなら操作出来ます

I need the volume of each chip to be controlled using the keyboard's arrow keys. First select it with the mouse, and then use the ↑ or ↓ of the arrow keys to increase or decrease the volume.
