I am not sure if these issues are down to iconfig or the firmware since I upgraded both at the same time.
However I am finding that:
1) When launching iconfig it is now taking ages to "find" and connect to the device. Used to take 2 seconds, now takes nearly 30 seconds.
I have seen this mentioned elsewhere and also a reply to say that it is Windows that takes a long time to scan the USB ports. That cannot be the reason however as prior to update of iconfig and firmware it was fine.
2) Sometimes when changing presets the device reboots and then is not found at all. The ASIO control panel shows no device connected, the iconfig software doesn't even appear to be searching. The only solution is to reboot PC. This seems to be a significant bug - it seems like the device, or the driver has crashed.
I think I *may* have some information that is helpful however: [EDIT: IGNORE THIS. Must have been a coincidence, I now have issues even without ipad connected]
My normal setup is with an iPad connected to usb port 1 (as that's the one which provides power) and my PC connected to usb port 2. I have not tested extensively, but it seems like the crash only occurs if the iPad is connected. If I have the iPad unplugged the device reboots and connects again correctly (albeit it takes too long as per point 1 above).
I wonder if there is something in the way the app or the firmware is written that means it doesn't make a connection to usb 2 if there is something connected to usb 1?
Anyway, if anybody else has a similar problem, try disconnecting your idevice from usb1 temporarily while you are changing the preset and then plug in again afterwards.
3) MIDI info tab does not seem to save the tickboxes. Sometimes even though they are empty they work, but sometimes they don't work at all.
4) The device has crashed on me (as in disappeared - Windows can't find it) when I change audio settings, ie from 16/44.1 to 24/88.2. Seems random, haven't worked out when it is yet. Could be the same problem with rebooting and not connecting again if there is a device plugged in to USB 1.
