Am I missing some way to assign a range of midi notes to a bunch of buttons? Even with the pad/grid widget seems like you still have to set each note to send one-by-one. Also doesn't appear to be a way to have a widget that transposes all the buttons to a different range, for implementing things like octave up/down buttons. Anyway I imagine a MIDI Keyboard widget would address all these pain points.

As Midi Looper in progress and related midi features planned. A built-in killer virtual midi controller make a lot sense. Currently Velocity Keyboard is the only choice for velocity sensitive input using iOS/iPadOS devices.

If this feature added after midi looper, I believe Loopy Pro will achieve the most portable yet professional "iPad only" music production/performance platform ever.

However, I think it's not easy to beat Velocity Keyboard in terms of velocity response. Also instrument design is important. I guess the best apaproach is actually the Loopy Pro interface itself, that is fully customizable.

I highly recommend the idea from the best coming hardware midi controller imo that has the same flat touch surface like iPad and can be configured just like Loopy Pro. In fact this product do midi looping. It worth to explore their idea and implementation.

edit: typo

I agree that this will be a great addition
