Thanks man, I’ll try to find these.
Charge only USB cables are not very common. I would say that you have to look specifically for a charge only cable. Cables that comes with devices has both data and charge capabilities.
Thickness doesn not necessarily tell the difference. There are usb cables in many different sizes and thickness.
There are different specs of usb cables especially USB-C cables but usually it’s how much wattage it can carry and this is mostly important if you need to charge a laptop that needs above 20w for example. And some carry more data etc but it’s mostly important if you need to transfer data from a fast SSD-drive. For musical equipment it’s doesn’t matter dor 99% if the time I would say.
But I always recommend to get the best cable you can afford to make it future proof

This is why I thought that if @JCFAX81 has tried three different cables, it’s not the cable. Possibly a setting on one side or the other.

Tried the 3 different cables again and definitely no audio coming out of my iPhone and can’t find any cables online that definitely state they send audio & midi.
I’ve reached out to Roland Support as I’m at a loss now.
You need. USB-A to lightning adapter for it to work. Make sure to use an Apple original. If you’re not using one audio will not transmit to the iPhone.
It’s a bit weird that you need to use one but most usb-audio products needs this adapter to work. Right now only products I know you can use without an adapter is Teenage Engineering TX-6 and OP-1 field because they are MFi certified.
Also these units don’t send the “mix in” signal to the usb so you will only be able to record the unit you are connected to via usb.

Thanks for the info. I’m currently using USB C to A cable, into official Apple cck adapter, from the mix out.
I’ve also got a Roland Go Mixer, so think I’ll have to go down that route.
Okey weird that you don’t get it to work… it’s not uncommon that you might need to open the camera app to unplug and replugg the cable to the phone… you can test the connection by playing something on the aria and it should be heard on the phone.
But I’m general a mixer is still better if you want more than one unit recorded. Hope you manage to solve it.

My cck device no longer works on my iPhone since recent firmware update.
On iPad I can plug it in and it starts charging
On my iPhone 11 it does nothing. ( if I plug cable directly into iPhone it charges )
Weird

Btw did you try to deactivate charging on the Aria unit by holding “exit” when powering it on? If not try that.
I don’t use the CCK but just the usb-a to lightning adapter and with that you need to do that or it will not work because the phone can’t charge the unit.

The T-8 has a setting called “AIRA-Link”. This must be set to OFF. Have you checked that?

That’s a steal!

I don’t think it has to be off. Mine was set to “on” on the S-1 and it works and it doesn’t state in the manual it has to be off.
Have you tried this? If confirmed then it makes my ask about the USB cable a moot point.
Looks like I’ll be using the Go Mixer to record.
Thanks for your support, same goes for anyone else that has pitched in suggestions!
Yes I have tried it and I thought it must just be a setting but confirmed it from a user here and Roland wrote it in a Q&A. You can read the manual about “signal flow” in the manual.
Agrees that this basically makes the usb-audio useless for me since I most often want to jam with 2 or more synths connected and record to phone via usb.
I would very much hope for a FW update to fix this but since it’s been like this since the first aria (T-8, J-6) was released I’m sceptical.

Getting the “mix in” audio signal via USB audio would require an analog-to-digital converter, which I’m assuming is not part of the hardware spec.

Demo with T-8, J-6, S-1

I’m noticing something odd with the J-6.
If I copy a sequence to a number of patterns, using the same sound on all, and then making tweaks to the filter, the cutoff frequency isn’t recalled correctly.
For whatever reason it seems to lower the cutoff.
I’ve tested several times. Tweak cutoff > write pattern > change pattern > go back….
Does anyone recognize this? Or could it be a faulty unit? 
Yep - this is how it works and it’s annoying. It’s been a minute since I troubleshooted this but from what I recall, the J6 can indeed save/remember different knob settings for each pattern. BUT - if you are tweaking knobs during playback, and then you leave that pattern and then go back to it, it will then remember and recall the last knob settings that you left that pattern with! NOT the original knob settings that you saved the pattern with. If you tweak the cutoff, then leave the pattern and then go back to the pattern, the unit will flick the LAST position of the cutoff that you left it in.
But then, if you completely power down the unit and then power it back up, the patterns will recall again with the correct saved filter cutoff position.

Got it, thanks for the info!
The strange thing is that this doesn’t work. If I save the pattern, and then turn it off and on again, the filter position has changed…
Same thing if I save the pattern and don’t touch the patch, go to another pattern and then back again, the filter is a bit off. Does it work like that for you as well?
I just tested it out…mine stays where it should. When I adjust the filter, then press shift-write and then push enter to save the pattern, if I change to a different pattern and then back again, the filter sounds to me to be exactly where I saved it.
Same if I power down, and then back on again. My newly saved patch still loads with the filter where I saved it at.
First thing I would do is make sure you have updated the firmware?
