Recently I've started to use the 12Step as a controller for a sampled keyboard I made in Beatmaker2 app, so that I can play wav's of keyboard chords with just one button. I plug the Ipad mini in a Focusrite Itrack Dock (http://us.focusrite.com/ios-audio-inter ... track-dock) which is the only ipad dock that has a USB Midi In port. When I plug the 12step in the Focusrite, it does not respond to the Midi messages, but sometimes, after a while, a light in the iTrack blinks and it responds to it perfectly.
The problem is, I never know if it will respond, and how much time it will take for it to recognize 12step as a midi controller.
If I plug in a normal Midi Keyboard always responds perfectly.
When I used it with Alesis iDock or Behringer iStudio with the Midi Expander it worked fine, so I guess it's something about the USB Midi messages not getting to the Focusrite from the 12Step.
Anyone has had the same problem?
