Hi Maarten,
So cool to update app, personally i'm waiting in app keyboard and midi learn...
THIS TIME FOUND MY GRAAL JUST IPAD AND VIRUS
I bought irig 2, tinyest i found, can be plug into headphone mini jack to get back audio of Virus
So lightning port is free for midi, play your app and send all sort midi data to Virus.
i can also play with all midi ipad toys (step sequencers ; multi keyboards and wired apps...).
All that can be recorded (in live !) direcly in my ipad Daw Beat maker 3.
I' M IN HEAVEN...
