Tweak the new features on the RK006: MIDI, Gate, Multiclock and much more! (Need Apple USB Connection Cable)

This is the manager-app for the RK-006 Master Hub.

The RK-006 is not just any MIDI Hub, it is a ultra-small device which allows you to connect MIDI or gate-driven music gear to your iOS device. Individual port filters, clock dividers, gate triggers and much more!

Not only is it an interface with 10 separate output ports and two inputs, It can also operate standalone: Even without a DAW, the RK006 can still host, connect and merge multiple MIDI/USBMIDI devices.

This app is an iOS port from the online webMIDI portal. It allows you to design and save configurations in the RK-006.

Some review snippets:

"The RK-006 is a game changer, making sync, MIDI and signal processing easy, even without a DAW."

"Retrokits prove themselves invaluable once again to our increasingly complex and confusing desktop hardware setups."

You can use the RK006 as a clock master not only with tap-tempo but can now also easily change the tempo via an assignable MIDI CC
