MIDI Macros enables you to create a collection of buttons (macros), which send out MIDI data when tapped.
Every macro can send multiple MIDI messages, to any of the connected MIDI devices.
MIDI Devices can be connected to your iOS device via USB, using the Apple Camera Connection Kit, or via WiFi.
Macro sets can be stored in presets. Presets can either be stored locally on the iOS device, or in iCloud, allowing you to synchronise presets between your devices.
