QU-16 Editor?

[garyh]

For iOS and Android devices, transferring folders of audio files through the cloud would be easy enough, and desktops and laptops could use the usb drive directly.

And yes, just using the multitrack playback for setting levels would be all that’s needed since you can’t adjust effects parameters using midi anyway. Now if A&H decided to release the protocol their iOS apps use, well that would be a whole new ball game. Until then, an app that could store levels, mix settings, channel names, etc. to files then send them to the board as needed, I think would be helpful.

I still don’t get why you’d want to ‘play back’ multitrack – you can set preamps based on something that doesn’t pass through them…

Give me the ability to save a scene to the iPad, and maybe export/import to/from Dropbox/iCloud/gDrive/eMail/??? and that would be great…

[garyh]

I could see a situation where you record a rehearsal, then offline, while playing the tracks, you could set approx FOH and mix/monitor levels and other settings for each song, band, scene of a play, etc. There may even be times where you need to change settings during a song. Basically it would become almost an automation tool where you can queue up your settings files and send them to the board at each change. You can do all this now using saved scenes, but the point of the offline editor is you wouldn’t need access to the board while creating the presets and someone could be making any needed changes to the files during the gig, on-the-fly, before they’re needed. You can’t do that while using the board.

Again, all of this would be subject to the limitations of the QU’s MIDI over TCP/IP unless A&H opened up their iOS API.

“How could you make Qu even better, you ask?” … Offline editor please!
Pretty Please!?!
🙂

By A&H’s thunderous silence, and their apparent unwillingness to part with the CRC algorithm that is needed by one who has the rest of an editor figured out, I’d guess the answer is nah. The QU is what the QU is – and it will never have an off-line editor, much to my chagrin. Really, how old is the platform now? I’m not saying they’re not busy, but there has been opportunity after opportunity that have passed.

CRC has been known for at least 10 months. And “findable” for a while now if you look around.
https://gist.github.com/nightlark/1e05f9afe5285dfcec89202c0e608104

Also, documentation on most of the file contents:
https://github.com/nightlark/qu-editor/blob/master/formats/qu-scene.ksy

[Ryan]

There’s also at least one person who has used it in some python scripts: https://github.com/antonmeyer/AH_DAT_Files (seems to be the implementation of the crc calculation that dtrt posted).

So @fxk, all of the information is out there — and my 10 month estimate was off, 21 months is more accurate. The big road-block is putting in the large amount of time required to make an offline editor.

[fxk]

Mea clupa! I missed the point in the thread where the CRC had been unraveled.
Please put my comments in the file “rambling of idiots”.
