I have question about the USB 9-10 switch :
If I select MST position, would it allow to act as an insert effect on master ?
I’m thinking of using my iPad with AUM to insert Klevgrand Grand Finale on the PX5 master.
master in -> iPad -> master out
Or do I need to sacrifice the 5th channel as return for this endeavour ?
Thanks !
The 9-10 switch sends the master out over usb. There’s no return to master so unfortunately this is not possible no.
The workaround of using channel 5 won’t do either because you’d be creating a feedback loop as channel 5 is also going to the main out 
indeed, using channel 5/A won’t do, you’re right…
but however it seems possible to insert usb on channels 1 - 8
as stated here :
Jup that’s possible 
plus using the fx send and return to channel A is great as well of course 
Here is my set up using PX5 with iPad as a master end of chain with something like FAC Punchlab or Maximiser, although this uses Digitakts class compliant audio to achieve this…there may be another way.
PX5 inserts send to Digitakt -> Digitakt USB audio into iPad AUM with Grand finale / FAC Punchlab (digitakts master out settings set to Off to prevent doubled audio) -> AUM goes back to Digitakt -> Digitakts sends processed audio back via inserts. There is a 10ms delay round trip (will vary on iPad model and app mastering used) but I don’t notice it as it’s applied to master stereo. Sometimes I use Transit (by Andrew huang) too…which Digitakt can also sequence if needed.
I also use the Digitakt compressor as a limiter as part of this set up.
Hope this helps in someway
Thanks !
That seems to be a nice solution indeed… atm I’m using a djm 750 + audient id14 on master out + ipad.
I guess your routing prevents from using any of the px5 usb channels given that AUM/iPad doesn’t allow to use multiple audio interfaces (or does it ?)
Correct. Although I still use a 2nd iPad / iPhone for the FX send on ch 9/10 using PX5 USB 
best of both worlds.
The PX5 pairs really well with iPad and has lots of potential configurations, I also grabbed a 2nd hand A&H Xone K2 as a midi controller as it uses Xlink to Px5 and then it all goes to the iPad FX over a single USB cable.
Simple question while I’m away from my gear to figure it out myself:
Can I connect the PX5 to my iPad Pro USB C port for quick and dirty video/audio recording?
Or do you need the camera connection kit gear?
Will a usb 3.0 hub with usb2 ports do the same job?
Should work yeah. It’s a class compliant audio interface. No kit needed.
I just tried. PX5 needs to be usb 3 to go direct. No biggie. Laptop works fine.
Hmm I’m fairly certain it should work. You need to have an app like AUM for example though
Ipad only connects direct to usb 3 devices without a connection kit thing.
Ah yeah usb b to USB c won’t work. But a simple usb hub solves that. Of course talking about non lightning port ipads
Edit: stand corrected. Usb b to c does in fact work
@Cashman I use usb B to usb C cables all the time on my 96, or usb B to usb A with the apple usb A to C adapter. No hub needed. Have an iPad on each usb port on the mixer this way. Only thing is it won’t charge the iPad, so your iPads will be running off battery power.
maybe a weird question….if you only use the left rca line input of the 4 (stereo) channels (say for a mono synth). Will the signal be summed to dual mono?
@jormesin Sadly No, using just one RCA results in the signal being panned left or right, this applies to channels 1-4. However the channel 5 for the mic has 1/4 jack that handles mono if only one jack is plugged in, also the external return can handle mono too. I use a small sub mixer for my mono synths and then into PX5. hope that helps!
Yeah, that actually makes sense. maybe it works with a mono jack rca split cable?
maybe, I’ve not tried. Does that just duplicate the signal? if so, it should work.
Mono to dual mono worked for me. Using this cable for a mono synth
