I just want to make some comments/tell my story of the new Frac Pad 1.0 app after playing with it last night.
I've been using an 2012 Lenovo Yoga 13 (touch screen model) as a Windows 10 tablet style controller for my Axe FX II XL+. On this computer Axe Edit works perfectly fine and is familiar, and also enables me to integrate soft synths via my DAW (Ableton Live) all with smooth and simple USB connectivity. But I've been slowly moving away from that rig and going to the Apple side. iOS/Mac OS devices afford some benefits to musicians in terms of simplicity of setup. The idea of running all the synth stuff in the background while having a ported version of Axe Edit on an iPad next to me on a music stand or anywhere for that matter (had a spare one lying about) was just too good to pass up so I bit the bullet and threw down US$39.99 for the Frac Pad 1.0 App. I should add that I've been using various iOS apps and controller devices over bluetooth to control soft synths in my DAW and so expected that to be possible with Frac Pad also (although not explicitly stated in anything I've read here).
After purchasing the app and attempting to connect I was frustrated. My iPad Mini was connected and visible as a Bluetooth device in the MIDI Studio on the Macbook Pro. However the app would neither connect to the 'Network Session 1' nor 'Macbook Pro Bluetooth' I/Os. Other MIDI apps were visibly transmitting as normal but Frac Pad 1.0 wouldn't even connect to sources.
So, I broke out a USB midi interface and a camera kit as suggested here and went the direct route. Wow! It connected! Frac Pad began to read info from my Axe but once completed the data was FUBAR. There were strange characters in the patch names and none of the actual blocked effects routing showed up; they were all empty. Mind you, this was using the suggested connection method. "No worries" I thought since Apple have a pretty simple refund process. I'd already wasted time on it and was thinking of past efforts like AxePad etc. that came and went and rarely worked and sucked either time, money, or both for ultimately nothing.
I decided to test a little more before giving up. I abandoned the USB MIDI interface and reconnected the iPad to the MacBook Pro via BT as previously (Using Midimitter). Only this time I set up a Mac OS app called 'MIDI Patchbay' and instructed it to send the BT MIDI OUT from the iPad to the AXE FX MIDI IN and data from the AXE FX MIDI OUT to the BT MIDI IN. Bingo! Now as soon as I set the I/O on Frac Pad 1.0's opening screen the reading of data from the AXE FX commenced, completed and displayed beautifully (much faster than over the 5pin MIDI Interface might I add). I was sitting on the other side of my studio space using the iPad wirelessly. It really worked perfectly. I was pleasantly surprised.
The app itself is a pleasure to use, almost a smooth as Axe Edit. No criticisms at this stage though I haven't really dug deep.
Great job, AlGrenadine. I'm still not sure why Frac Pad 1.0 wouldn't work properly over the 5pin USB MIDI interface (iConnectivity MIO) but I'm really glad it works wirelessly over BT with the Macbook. If you use an anchored laptop in your setup (like I do) and you have a spare iPad lying around I'd certainly recommend Frac Pad 1.0 as a way to edit/control your Axe FX in a manner far more simple than using the front panel access of the Axe FX itself.
BTW, I also have an MFC101 connected over FAS and both it and the iPad devices work seamlessly together. I'm happy as a pig in Mud right now
Edited: The next step will be to see if I can get it to work the same way with the WIN 10 Yoga 13 Ultrabook so I'll have a backup in case of computer failure etc. Not much idea about MIDI over Bluetooth on that platform though.
