I have created a simple PC program to multitrack record / playback from the QU-PAC
Just plug the USB cable
Press REC
It will record 32 individual wav tracks on the hard drive , that you can then playback again to do soundcheck easily
I initially created this app for my previous mixer the Behringer XR18 that I have replaced by the QU-PAC now.
The XR18 had no USB DRIVE direct recording possibilities like the QU, but I think this tool can maybe profit to people here too, so I have adapted it to work on the QU series too.
USB2 should be sufficient…
You wouldn’t be doing anything else on it at the time.
The SD card I/O is independent (though possibly a bottleneck, I haven’t looked).
Given that people can happily record TV from a USB tuner to a USB HDD on the same Pi, I suspect the bandwidth would be there.
It was rather tongue in cheek because the OP has clearly made a Windows program…
Bandwidth of multichannel WAV recording is considerably higher than recording a single (compressed) TV stream, and the filesystem needs to handle overhead for multiple write streams (FAT management etc.) compared to only a single one. So its not that easy to decide.
Yes… I only know Windows programming…
By the way, today, I buy some very decent windows 10 tablet from china for only 100/150 eur
What monitoring do you need?
The QU already do direct monitoring
I am wondering if you can have the below option also in the software: an app that will display
the meters level of all channels, mixes, LR, FX, … ,
and the most useful, the selected (PAFL) channel/mix should show its own spectrum analyzer in the bottom of the window
and all of this in one window
These features are available in the ios app and android but it doesn’t fit in 1 window, so have to dedicate a small PC (since most of theses are MIDI datas) to show all the meters data (using usb or ethernet)
If you are using C# then I can help you in the front end design (eg. WPF)
