Here's a video with Sonicstate’s Nick and Gaz having a ball with the RK-002 (mind you the RK-002 now is shipped with a new 3D-printed orange plug end as opposed to the version in the video. Also we have increased the length to 1.5m).

The RK-002 ‘Smart MIDI cable’ has already found it’s way in various setups, not just for the volca Sample. It looks like a +/-1.5m ordinary  male-male MIDI-cable but has a microprocessor on board which ‘bends’ midi data on the fly.

We initially developed the RK-002 to solve the KORG volca Sample’s MIDI behaviour but in the meantime we have brought various other firmware flavours:

  • Arpeggiator firmware
    Adds arpeggiator capabilities to your MIDI
  • KORG volca FM firmware (or Roland Boutiques)
    Actually not only to add velocity data to the volca FM – it’s a more versatile firmware version which is able to add extra controller mapping to key, aftertouch, pitch and modulation. This can come in handy on various MIDI devices.
  • KORG Kaossilator firmware
    This firmware allows you to play the KORG Kaossilator from a regular MIDI keyboard.

SETTINGS

The RK002 firmware is updatable via MIDI, you can implement the RK-002’s sysex messages in e.g. a MIDI controller or visit the settings page. In this page it’s also possible to change the parameter mapping.

MIDI POWER

To keep things portable and solderless we decided to make the RK-002 MIDI-Powered. This means the embedded controller is powered by the MIDI bus and you don’t need an extra power supply. Beware though: Although power consumption is very, very low: Not every MIDI interface or device supports MIDI power! In order to make the RK-002 work in these cases there are multiple options, but if you want to work with what you have at hand; Sometimes looping the RK-002 through another synthesizer’s MIDI-In -> MIDI-Thru port can solve the problem. Our RK-004 MIDI merger/splitter also does the trick.

RK-004 TEAMUP

You can drive the RK-002 via our RK-004 when you set the MIDI port to ‘out mode’. Added bonus on the RK-004 is that you can update the firmware via an audio signal, e.g. people who use the RK-002 with the BeatStep Pro (which filters out our firmware SysEx messages) can now update their RK-002 via a plain and simple MP3 file.
