Hey @NZdave,
The recent maintenance firmware updates to Qu are related to changes in hardware and a bug with talkback metering, so if you are not using brand new AR/AB units there will not be much benefit to updating.
Saying that, if you’re like me you’ll want to update anyway!
We always ensure the MIDI commands in the console stay the same, so there will be no difference there.
The DAW/MIDI Control app does not have any bearing on the audio side of things and when connecting to a Mac there are no drivers… V1.95 included changes to the USB-B connection and you’re already running this, so there will be no difference or problems there either.
In short, no, there should be no change, but if you do update and have any issues, just contact us directly using support.allen-heath.com and we can dig out and send over your current version of fw to reinstall.
Cheers,
Keith.
