A tuner for the mapping editor page

This would be very helpful. Like a guitar tuner or something.

A great idea! a little built in tuner.

As a stand-alone, this would be a good tool to have. As a plug-in, not all that necessary, as Cubase and most other DAWs all have tuners available for channel inserts…which is exactly what I do when I’m sampling in HALion in Cubase. But even so, its own built-in tuner would be a real convenience.
