Can i route my master fader (or headphone out) to the Qu-Drive usb – b port and insert a USB Bluetooth receiver which would pair to wireless bluetooth headphones?
I’m going to say no because the Qu Drive USB has multiple audio feeds present at it all the time you can change the patching source of those. For an input of sorts to the QU Drive it’s looking for a WAV audio file playing back from the USB stick.
If you want to use your Bluetooth headphones get a small Bluetooth transmitter and connect it to the headphone jack.
Keep in mind there may be a lot of delay on the Bluetooth audio connection.
