Hello, I think I started this thread and then abandoned all those who followed.... sorry for that.
The reason I've found my way back here is because I have had a lot of painless pleasure using an FBV Shortboard MKII with an iPad 2 ios6. So much so, that I've just picked up an FBV Express MKII as a slightly smaller setup. BUT, the FBV Express MKII shows absolutely no sign of working. It powers on (via powered USB hub), but the iPad shows no sign of recognising it after plugging it in every order imaginable.
Reading scraps of info elsewhere, at least one person reports the Express working in IOS5 and another that the Shortboard does not work in IOS7.
In my setup (back in IOS6 / Ipad2) I have a Tascam IU2 audio interface (into USB hub) which needs to be plugged in in a very specific order to work properly, but the FBV shortboard is very unfussy, I can plug it in and out of the hub whatever the iPad is doing and it always registers and works straight off.
If anyone can provide any hope or advice for the Express then it would be appreciated. As an alternative, I can recommend the Logidy UMI3 for Loopy, but the switches are no good for toggling effects in JamUp or Amplitube (they don't 'latch' in IOS though they will on Mac/PC with utility software running). It does have an expression pedal input as well which I have used to control the Wah in JamUp.
What I find perplexing is surely there is someone at Line 6 with an iPad who is interested in App control? Why can't they be more forthcoming with information, even if it's bad news?
