So for the Yamaha MD BT01 to work I have to open midimttr app to connect the bluetooth device. It does not show up under bluetooth in the settings menu for (me anyhow) until I do this.
So first plug the BT01 into the back midi in/out ports of the axe fx
2) open midimttr app,
3) connect client "MD BT01" in midimttr app,
4) open FracPad and select the MD BT01 under midi in/out.
When you select the amp block you get a 1 second pause so maybe a slight bit longer than axe edit in that regard but other than I did not notice any lag. More time, more users and I'm sure Al will receive tons of wishes and suggestions as we go. But the initial design is great if you ask me. Swiping through menus sure is nice. Its got me thinking at practice how easy adjusting presets could be now even just with your phone.
Also I paid for the app on my Ipad and was able to download it free to my iphone so only one purchase.
