Hi again, thanks for pointing me out, I'll speak with him and ask for some directions.

I wanna share some technical details about what I'm doing: I'm currently reverse engineering the sysex communication between Eleven Rack and the macOS app to be able to do the same from the iOS app.

For now I'm only retrieving the rig names and amp+cabinet and filling a collection view with 4 sections: favourites, user banks, factory banks and local-only(*). Tapping the rig, changes the current program on 11r and shows a stomp-box menu for bypassing individual effects. A button for editing programs will also be available, but I am not there yet.

* Local-only will be an offline storage on iOS device, so patches can be created away from the Eleven Rack (if this somehow makes sense) or ideally downloaded in form of tfx files. The same way you can do from the macOS app, it should be possible to use a rig that is not installed on Eleven Rack, extending the limit of 104 user presets.

I'm writing it in Swift, probably will open-source the code as soon as it gets more stable, and contributions will be welcome. I'm doing for fun in my spare time, it won't be paid, ever. Initially compatible with iOS 10 and 11r with Expansion Pack, any screen size for iPhone or iPad.

It's possible to connect using Apple Camera Connection Kit (a powered USB-hub may be necessary) - connecting directly 11r to the iOS device or with another device in the middle (audio interface, for example), as long as it forwards sysex messages. Another possibility, which is working but not very well yet, is to connect wirelessly using MIDI Session Network.

Before the end of March I may have some really basic alpha version on TestFlight so I post here again to ask if anyone will be interested in testing.
