I wish there had some forethought regarding incorporating a USB port on the Maestro. For many folks a USB connection might have been a better method to do updates and create and archive setups via Windows or Mac software versus a sole reliance on BT. Not long ago I attempted a firmware update on a PA speaker that uses BT for EQ control via an Android based tablet. During the update something failed and the connection was lost and it appeared to have bricked the BT hardware in the PA speaker since I can no longer see it to initiate a pairing Fortunately the speaker still functions and EQ tweaking wasn’t essential. I keep thinking if it had a USB port I might have been able to reflash the firmware and possibly recover the BT.
The lack of the USB port on the Maestro is very much the reason I likely won’t buy the Maestro even though it has all the bells and whistles I would be looking for otherwise.
