Apologies for not getting back to everyone straight away - especially the Beta test team (new) applicants.
I decided to 'dive deep' again into the code to make some major improvements in a lot of areas. I also managed to borrow an iPad2 while waiting for my iPad3 to arrive from Apple Australia... and... I've managed to FIND the damn bug that was causing the iPad2/3s to crash. There were actually several buffer overruns happening a few spots.
Fixed those, and things seems to be a lot more stable on the borrowed iPad2.
I've also decided that instead of just another bug 'patch', I would try and do a bit more on the features of AxePad, so I have successfully put in a 'Tap Tempo' function (just tap the area around the tempo light on the first screen to set the tempo on the Axe-FX).
Also, I have been refining the Axe-FX II parameters (e.g. 'Gain' is now 'Drive', GEQ block has 9 sliders instead of 7 etc.).
I've also implemented the 'Boost' and 'Bright' switch, and put a 'Speaker Drive' knob on the amp screen as per popular request:
I'll be spending the Easter weekend testing and refining these enhancements, plus a couple more minor ones, then pushing it out to the beta team, then to the App Store.
Thanks for your patience everyone!
