See the below screenshot. When I right click on the volume slider for a channel in the mixer, the options like "copy value" all display something like "1.25%" when the channel is really at 125% volume:

Edit: The channel send knobs are also bugged in the same way.

I've checked the other areas of the program and found some other discrepencies:

• The master volume slider at the top of the window does not include the "%" unit in the right-click context menu (though it does include it for the tooltip when editing). That is, volume readouts are just "100", or "85", rather than "85%".
• The master pitch reports no units in the context menu, though it too includes units in the tooltip. In contrast, the instrument-specific pitch knobs do include units.
