We've been getting lots of great details, over the last couple of weeks, about this update and it is finally approved!New in this version:
• Now with MIDI Designer 1.3.7, you can now control other iPad apps via Virtual MIDI.
• Snap to Value: Building on snap-to-default, snap to value lets a supercontrol button snap a subcontrol to a certain value in a certain amount of time, or at a fixed rate.
• Rolling over buttons reverses state: multiple buttons can be reversed or activated with a single swipe.
• Configuring hardware MIDI connections has been completely revamped (along with virtual MIDI endpoints).
Here is a tutorial on setting up Virtual MIDI.
