I just bought a Roland VT-4 (voice transformer). It's a riot.
After installing the drivers on my Mac, the VT-4 is detected as a microphone (and speakers). I can use it with Skype, Zoom, etc.
I'd like to use the VT-4 to make phone calls on my Android phone. Does anyone have any thoughts on how to do this? Could my Mac act as a Bluetooth headset for my Android phone? Or is there some sort of Bluetooth headset/device that accepts line-in?
Is there a Mac equivalent of HFP for Linux?
