RK-0062.09 - App Store

This is the manager-app for the RK006 Master Hub.

The RK006 features a 12 bus(yes, 12x16 channel MIDI Handling) MIDI Interface and and ultra stable MIDI clock generator. It can MIDI merge from it's two TRS-A MIDI Inputs and even add four self-hosted USBMIDI devices to the stream. It is able to connect your iOS device not only to MIDI but also act as a CV/Gate source with control straight from your DAW. Add extensive MIDI filters and even built-in polychaining to make this the go-to tool for any setup.

This app is an iOS port from the online webMIDI portal. It allows you to design and save configurations in the RK006. Via this app you can setup presets which can handle event filtering, clock processing and RK006 port output modes (MIDI/Gate/CV)

Some review snippets:

"The RK006 is a game changer, making sync, MIDI and signal processing easy, even without a DAW."
(juno.co.uk)

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

"Incredibly versatile hub for MIDI, USB and modular, and probably the only MIDI interface you’ll ever need in or out of the studio."

-Change in low speed tempo triggers (1 per Bar, 1 per 4 Bars, etc)
-High precision BPM Internal Clock Generator
-Internal Clock Control moved to the toolbar for always access while working on port outputs.
-access to more poly chain options; Round Robin / Voice Reserve mode
-INSERTCTL parameter for adding MIDI FX chain inserts (and RK008 Real Time MIDI Recorder integration) 1.5 06/14/2022 Added USB filter presets for more devices.

1. Added multi clock capabilities from DAW.
Port 1-10 clock can now be individually shifted from DAW preferences in e.g. Bitwig, Ableton to accommodate laggy devices.

2. Added Easy CC control for per-port clockshift/dividers
MIDI channel defines on which port the clock will be divided.
e.g. Define CC 80 --> CC80 value on channel 4 changes clock divide on port 4

3. Easy CC control for internal tempo generator
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
