Hi Escapegoat!

Well done in finding an alternative earthing point that solved your noise problem :clap:

If only all grounding issues were so simply and elegantly solved!

Hi all,

I'm running quantiloop pro on my ipad 3rd generation (30pin connector). I want to connect my usb alesis io2 souncard to the ipad so that I can use the inputs on the soudcard to play and record loops on guitar/vox. I went and bough a camera connection kit (30pin to usb adapter) and a usb 3.0 power hub. When connecting the hub into the ipad I get a message 'USB hub 2.0: the connected device requires too much power'. This is happening before I connect the soundcard into the usb hub which leads me to think the usb hub is not working might not be compatible with the camera connection kit?

The other issue that comes to mind is newer versions of the ipad run usb-c to apple lighting/usb 3 connector which means the ipad gets power from connection the charger into the usb 3 socket. Could this be the issue as my ipad is not getting power from anywhere?



Many thanks

Hi Piloadami

'USB hub 2.0: the connected device requires too much power'. This is happening before I connect the soundcard into the usb hub which leads me to think the usb hub is not working might not be compatible with the camera connection kit?

It sounds like the hub is not receiving power independently (presumably you have an AC-DC adaptor for it) and is therefore trying to draw power from the iPad. Can you check this? For example, does the hub power/charge other devices (keyboard, phone etc?). iPads are fussy (by design) as to which peripherals they will work with. Cheap (non-apple) options can fail, but then again, there are usually no apple-produced options for older devices like your 30-pin iPad.

Also, I recall that the Alesis "iO2 express" will not work with the iPad, irrespective of power arrangements. I hope you have the older iO2, which is at least theoretically compatible if you can get the power issue resolved.

One thing: Apple lies about USB power consumption. On some models on later versions of iOS, a USB device which won't work (popping up the message you saw). But it WILL work when connected via an UNPOWERED hub! Sounds completely batty but it's true. See here for one example: https://www.youtube.com/watch?v=J-I-nnocYtU

Of course, this might not be the only problem you have if the Alesis is not iOS compatible.

(Like you I have a 3rd gen iPad and Apple's CCK and after an iOS update the USB thumb drive I had suddenly "consumes too much power". Complete Apple BS. I got a £2 unpowered USB hub as shown in that video and the thumb drive now works fine. I'm pretty sure that Apple's arrogance makes third party suppliers think twice about making devices for iOS.)

Actually, I just rummaged through my files and found soemthing called:
AlesisPhotonX25-usbfix_v1_04.zip - which mentions WinXP in the readme file.
Don't remember using this, so you would be on your own. I will PM you with a link.

Hi, Bill.
I'm looking forward for the PhotonX25USBfix_v1_04.zip file. Do you have it? If so, will you send a valid link for downloading it? I'm driving crazy looking for it in internet!
Thanks a lot.

Escapegoat, I have had that warning about a memory stick, "Insufficient power for device" on a desktop PC even though the same port would happily run a bus powered AI!

I don't think it is just (or at all?) a power issue, maybe more a "handshake" problem?

Dave.

Working on Windows 10 !!!!!
Thanks a lot, BillB!!!!
But it was a headache to install windows XP with a virtual machine, and to have the files in the XP system. It couldn't read an USB device, it couldn't share files with host machine (running virtual machine under windows vista), it could't connect to internet neither via WiFi nor via ethernet cable. Finally, I decide to try with a really really legacy device: a CD :lol:
Surprisingly,I found a blank CD in a drawer, I burned it and... it worked!!!!!!!!!
Now, my alesis Photon X25 works perfectly in Ableton 10 Live! Even the axyz 3D controller dome!!!!!!!! :clap:
Thanks again, BillB for bringing to life my old Photon X25!!!! :thumbup:

Excellent new, smntk - glad you got there in the end! The X25 is quite a neat little keyboard.

I had to do an all battery powered gig this summer including the PA.
I was running two mics into Quantiloop running a few tasty FX then passing it back out to the PA.

I bought the Zoom U-24. It’s a fantastic interface and very versatile. Battery life was good but I turned it off between sets so can’t say how long they last. It’s not as solidly built as say the H4N so I wish there was a plastic case for it to protect it during travel like there is for the H4N.

2 mics/Zoom/latest CCK/iPad Pro
while sending the outputs of the Zoom to the PA and headphones and the H4N recorder.

First post here - HI EVERYBODY. Made an act after seeing this iOS section of the site.

Currently running ALL sounds / synths / drum samples from iPad Pro 2 into Ableton 10.

I'm using the Zoom U-24 with the USB 3.0 CKK+ and a 30w USB-C (macbook pro) power block. The Zoom handles Audio OUT from the iPad, Audio IN from my guitar (Hi-Z ch.1), and MIDI IN from Ableton.

Connected to the laptop is a Focusrite 2i4 for audio IN from U-24, Audio OUT to a Mackie ProFX8 Mixer/amp/speakers, MIDI OUT to the U-24, plus all the MIDI hardware IN. Routing and recording is handled in Ableton.

I will also occasionally use my old iPad 4 for Touchable Pro (insane ableton control app) or Expression Pad MIDI OUT to the synth on the iPad Pro.

It's taken about 2 years to get this right... but it's finally working to the point I'm satisfied. The sounds + instruments available on iOS are not only high quality, but usually cost 1/10th what they would on PC.

Thanks a lot.

Any chance I could get a copy of AlesisPhotonX25-usbfix_v1_04.zip and any related files as well? I just picked up a used photonx25 on ebay and it still has the old firmware. Thanks!

I’m a big fan of the Behringer UMC204HD. Got two of them. I’ve had Apogee and others, I don’t see how the Behringer is in any way inferior. I certainly haven’t experienced "muddy" sound with it. The only problem is the prices on the Behringer keep going up. I got both of mine for less than one would cost today.
