RK-008: Real Time Multitrack MIDI Recorder


The RK-008 allows 8×16 MIDI channels of easy, unquantized MIDI recording just the way you’ve played them. Notes, pitchbend, controllers, program changes,… the works! Use it as a free music making arranger or as a merger, a router, a filter,… – and on top of the realtime recording there is also the possibility for stepTime input which houses the mother of all ‘p-locks’

Inspired by the Alesis MMT8, garnished with 21st century goodies and available in two stylish portable flavours. The RK008 comes with two TRSA-DIN5 cables and one USBA-USBC cable.

Note that we can’t ship the RK008 with a Li-Po battery because of international shipping regulations. We designed the RK008 to work with a widely available and not too expensive’retro-battery’ typed the ‘Nokia 5C’. It’s available on ebay, amazon or maybe even your local smartphone repair shop

Note: The RK008/70s wood orders generally need a day/few days extra to customize the wood panel build.

The RK-008 is our portable Multitrack MIDI Recorder. Inspired by the legendary Alesis MMT-8 (what’s in a number) it features the same simple workflow: Redo recordings or overdub, stack parts, mixdown, …

It’s similar to recording audio but instead it records the MIDI core of your performance, allowing you to produce the sounds even after you’ve played your part.

And where back in the 80s you needed to stop the MMT8 performance for those nifty operations like quantisation/swing or the transposing of recorded parts, the RK-008 can do this in a non-destructive way while playing: You can just experiment or revert without having to stop and commit these changes to hear them on your performance.

Last but not least it pairs up perfectly with our RK-006 / RK-002 and can be that extra accompanying music brain to sketch musical ideas, add MIDI routing – or play on your side in a live hardware setup.

Features in short:

Easy recording of MIDI events
– just the way you’ve played them. Notes, pitchbend, controllers, program changes,…  the works.

16 Songs with each 100 Parts. Each Part can contain 1 to 680 beats length of music or the RK008 can be set without tempo at all.

8 Tracks per Part, each able to record and play full 16 channels of MIDI. Unlike a sequencer, the RK-008 tracks do not have restrictions on polyphony or MIDI channel (unless you set them) – Each track can contain data for all 16 MIDI channels if you want.

Non-destructive Part Modifiers – Each part can be individually transposed, quantized, swinged, filtered or set to a different MIDI channel or even – to seperate RK-008 (or RK-006) outputs.

2x MIDI-In, 2x A MIDI-Out + Sync Out.TRS-A MIDI connectivity. Tracks are routable and also expandable via USB with our 12-port RK-006 USB Host/Interface.

A portable form factor (13x8x3cm / 5.1×3.1×1.1inch) with user-installable LiPo battery power (Type ‘Nokia BL-5C’) allows you to play with the RK-008 in any situation.
