Real-time MIDI arpeggiator, usable independently (internal sounds) with instruments installed on the iPad or with external devices

I use l0interface iRig MIDI IK Multimedia for connecting external devices, but it is possible to MIDI "wireless" wifi MIDI Network

The application is installed su iPad 2 with iOS 7.1.1

I fell in love with this app which often allows me to start compositions, accompanying or driving my Roland Fantom G7

The application is super well designed in terms of ergonomics, the manual is clear and French, no latency, the app is regularly updated.

Presets originally installed and can store its own settings, quick and trouble free installation, I rarely had a crash of the application.

I drive other app on my iPad, or an external synth (Roland Fantom G7)

I use it for 2 years I believe, I have not seen any other similar iPad app also easily accessible.
