Do you want…
More faders on a QU,
Monitor engineer’s desk,
Easy remote control?
Are there times when you want a few more faders. maybe you’re running all the channels and just need a handful of group/DCA/FX faders at hand as well?
Well - now you can (almost**).
Although QuPad doesn’t support USB MIDI controllers the Android app ‘Mixing Station Pro’ does, and this offers a way in.
I’ve been thinking about this for a while, and have a BCF2000 MIDI controller (8Fader+Rotary+2buttons on the main area) for this very reason.
Recently I spotted a note that RTAndroid had been released for the Raspberry Pi 3 - finally a device that I could use to make a good solid connection, with power, USB, ethernet, wireless all built in and usable at the same time!
So I went off and installed RTAndroid (Free): https://git.embedded.rwth-aachen.de/rtandroid/
On the Raspberry Pi 3 ($35):
https://www.raspberrypi.org
Due to licensing issues the install requires a linux box with ads tools installed (a VM is fine, you only need to run two scripts)
Before the Google Play store etc can be installed (a second script provided with the installation download) you need to:
Enable developer options.
Enable the terminal.
Open debugging to the network:
su
setprop service.adb.tcp.port 5555
stop adbd
start adbd
Afterwards disable the network debugging:
su
setprop service.adb.tcp.port -1
stop adbd
start adbd
I could then install Mixing Station Pro onto the Pi, and it was quite happy.
I hooked up the BCF2000 and started to configure it - the faders always map onto whatever faders are on screen, I set the top row of buttons to access each monitor mix by name.
So my final setup was:
QU → Ethernet switch
Switch → RPi
Switch → WAP for the QuPad and QuYou users
RPi → BCF2000
RPi → Touchscreen (HDMI->DVI + USB)
RPi also had a keyboard and mouse attached
Overall the setup worked well, and provided me with an additional 8 faders - sometimes I used them as a monitor engineer’s desk (during setup) so I could be doing FOH and the monitor mix adjustments at the same time, during the gig I had an extra few faders for easy access.
Those faders can be anything that the Mixing Station app can show - so they can be anything, in any order.
I think, although I haven’t checked, that I could use some of the buttons on the right of the BCF2k to control which layer of faders I am using.
Below is a photo of the setup at a gig on Saturday.
The Pi is to the right of the desk (all the cables were long, and so I tucked them out of the way under the QU). The BCF2k is to the left of the desk, and the (fully working) touchscreen is above that. My iPad completes the tech lineup…
One additional benefit is that the Mixing Station app puts the RTA under any EQ that is going on - and that’s nice to see…
Of course I could have used a WiFi connection, and for a smallish band (I could get away with this most times) just set up at the back with this setup, and leave a QU on stage. As it happens I have an AR2412, so I don’t need to, but it’s a much cheaper option than a stage box.
** almost…
The biggest issue I faced was that RTAndroid is still clearly a beta release. It spent an amount of the second half of the gig in a reboot loop, optimising apps and then trying again. It sorted itself out - I just ignored it when it went wrong.
But there are tablets which run Android and have Ethernet and USB ports - so given different tech, or a little bit more development on the RTAndroid code… This could be a rather nice option.
