Feature Request: Applescript control for sliders

[ihorner]

I'd like to be able to set sound source volumes via AppleScript or similar — I can't seem to find any information regarding this, and the dictionary seems to only apply to setting output.

I'm using BetterTouchTool to send volume levels from a midi device with faders, and I'd like to associate the faders with different sources in BackgroundMusic.

Good idea. As far as I can tell, the AppleScript API only supports reading and changing the output device so far.

@kyleneideck how can you do that? that'd be pretty useful on its own.

sorry, I'm a bit of an AppleScript noob. is there some way to explore the API of an app?

edit: found via "Open Dictionary" in AppleScript Editor...

tell application "Background Music"
	set selected output device to (output device "External Headphones")
end tell

but yes, +1 to this, and being able to set volume of the output would be great too. macOS built-in set volume output volume 40 is really slow.
