Yes – when play is pressed audio shows on the meters.. and can be heard via ST3 – to the main mix o/p
— but i am wondering why i can not feed via the ‘main’ layer as i would any other source.
This came about because I could hear audio playing but had no faders open – on the main layer that is. So went investigating as I sort of felt this could catch me out when in the heat of battle and wondering where the audio ( possibly intermission audio) was coming from if I had not stopped the USB replay. It turned out the ST3 fader was open on the master layer (i.e. layer 2 (not the custom layer))
Further investigations showed I could ‘select’ USB audio as a source on the main layer via the USB pre amp button…. but could not actually hear any audio. The source on the channel even changed colour and label as per the instructions on page 23… but still no audio
2015/12/20 at 10:39 am #52847Wow xapbob you sound like a Pi expert…. even @ $50 it is cheaper than a $1k mac on site
For those of us not as familier with the Pi – Could you elaborate on the technical terms please
– what is the SOC – is that the brains of the Pi ?
– and the NiC?
– the SSD – taking a guess — solid state device – i.e. the flash card possibly?
– longer wear levelling/internal check — No idea on this one, sorry2015/12/20 at 10:12 am #52845Cheers for the tip xapbob – i had not heard of this blog https://churchtecharts.org
2015/12/20 at 10:08 am #52844Sorry xapbob my error with tracks– was late at night-
My idea was based on how a laptop works when you send something to print but have no printer connected. The file goes into a buffer area and awaits the next connection to a printer.
My thought was – I wonder if the 32 tracks of audio could be ‘buffered’ and then downloaded into Pro Tools / reaper etc at a later date ? Thus avoiding the need to have a full computer setup on site. It would also save time arming and setting up tasks when in the heat of battle… And the risk of a ‘hang’ whilst recording thus loosing everything and awaiting a restart etc…etc…
Not being a tecchie with such things might the zero ( or a full version Pi) also provide a cleaner stream for recording. i.e. could it have a larger buffer to avoid any dropped data and error trapping to ensure a complete recording… possibly to two flash drives/cards as a raid array?
Might it also save as you go along so if it did crash you would at least have something?
Your idea of feedback lights is great and the one press start stop is inspired
This sounds exciting — a crowdsourced Christmas project… thoughts anyone?
2015/12/19 at 10:12 pm #52830I agree the QU records — but only 16 channels to the USB stick ? I was wondering if a device existed that could record all 32 channels via the USB socket on the back of the unit. A sort of data stream recorder black box – i.e. record without the need for a fully fledged computer at an event running pro tools or reaper.
2015/12/18 at 4:35 pm #52802PPM’s would be great also
2015/12/18 at 4:13 pm #52800An offline configurator would be a great tool. I have just done an event where time was critical on site and found myself rigging the gear at base inc 32 way input boxes so i could get all the patching and labelling done ahead of time. Being able to do this on the train anywhere would be fantastic.
To take this further, and as a slight dyslexic who works best with images, some easy way to visualise the configuration would be very helpful. I find myself drawing with a pencil on that old stuff they call paper my rig outline. Now if the QU could output that data as a screen display on the iPad you really would be helping many people.
2015/11/26 at 4:46 pm #52322Cheers Andreas for the figures. So if my maths are correct when looking for the flash drive required :
1 x 7.5h session of 16 tracks at 4 GB each (roughly) = gives a minimum theoretical flash drive requirement of 64 gig ( ideally larger due to headroom etc i would suspect)
Whilst on about sizes if a drive becomes full does anyone know if:
— it protects what has already been recorded
— has any buffer within the mixer to allow a swap of drive
— advises of imminent data crisis – 10 mins out possibly?— if no to any of the above maybe these could be features in a firmware update?
2015/11/26 at 3:02 pm #52319Update:
Over the past few days I have been plodding through the setup however I can only get the DAW to work one way around – so something is still not correct.
I can get Audition to see audio played via the mixer and I can get the faders to react to click and drag on the screen i.e. within Audition… but I can not work out how to get the faders to control the screen faders ? I assume you should see them move up and down on screen as you move them on the console?If it helps I also think that other functionality is not crossing the USB lead either way i.e. gain, pan etc.
Other bits of background that may just assist others in setting up:
I have installed the A&H DAW Control driver (1.03) https://www.allen-heath.com/key-series/qu-series/#tab5
and used https://www.allen-heath.com/media/DAW-Control-Setup-Notes-V1.30.pdf as a guide – i.e. custom layer set to midiSetting it to Mackie – midi ports – in and out midi. The squares flash on data ( i.e. left for up, right box for down)
I have also selected within Audition – preferences – Control surfaces –
—-Device class – Mackie
—-in the configuration pop up – I have added 4 times (1 each for each bank of 8 faders on the desk) the input device/ output device i.e. midi 1 for bank 1 , midi 2 for bank 2 etc.but still it does not work transparently? Any thoughts much appreciated?
Adobe Audition CS6 – 5.0.2 and Mac 10.10.5
2015/11/24 at 4:03 pm #52260I had an interesting experience late last week with an Integral 32GB memory stick I had around the workshop.
It recorded multitracks fine for almost 2.5hrs then started to throw errors as it came close to what i can only assume are a maximum file sizes.
Drive became so corrupt it would not read.
Thankfully it was a soak test – with a non approved but readable drive. However, I do take away one learning point – . Test the recording parameters beyond what you may need to use.
Just out of interest what are the maximum single file sizes / recording durations — anyone know?
