Nanokontrol2 the Digitakt

Here’s a quick template for controlling the 8 sample tracks from the Elektron Digitakt with help of the RK006 hosting a Korg NanoKONTROL2

The NK2 template can be downloaded here on google drive It assumes the 8 sample channels of the Digitakt are set to MIDI Channel 1-8

There are multiple ways to connect the NK2 to the Digitakt via the RK-006:

1. Connect the OTG dongle to the RK006 and plug the NK2 into the USB-A. Then connect the Digitakt to any of the RK-006 outputs

2. Connect a USB-HUB to the RK006 and connect both the NK2 and Digitakt to the RK006

In terms of control it will not make a real difference to use one connection or the other. The upside of connecting all via a USB hub is that all outputs of the Digitakt are now also available through the 10 output ports on the RK006 – double win 🙂

Make sure that if you are hosting the Digitakt to the RK006 the USB mode is set to USBMIDI, not overbridge.

RK-005 and Teenage Engineering OP-1 Support

Buy the RK-005

RK005 OP-1 Support

Because many people want to pair the RK-005 to host Teenage Engineering’s OP-1 we have implemented direct communication with this device on the 1.4 firmware (and up). You can use a small menu on the display of the OP-1 to access various settings of the RK-005. This is done via the OP-1’s ‘Controller Mode’ which is also used in certain DAW’.

USAGE

First; Make sure the OP1 MIDI CTRL Channel is set to CH1 and the dial is set to ABS, MIDI CC

To enter the RK005 menu on directly on the OP-1:
– press’SHIFT’ + ‘COM’
– press CTRL

to leave the RK005 menu:
– press ‘SHIFT’ + ‘COM’
– press ‘OP-1’

OP-1’s display will show:

+-----------------------------+
|            RK005            |
|     [|||||||||||||||||]     |
|     USE < > REC and 1.8     |
+-----------------------------+

now you can use the following buttons:

‘<‘ to navigate one menu page to the left ‘>’ to navigate one menu page to the right
‘REC’ to change the currently displayed parameter
‘1..8’ to perform parameter dependent settings

Note: parameter changes are NOT stored in RK005’s memory until the menupage ‘STORE IN RK005?’ is executed (see below)

Menupage : ‘DIN-THRU’

Description:
this parameter controls the forwarding of MIDI data from the MIDI DIN input to the MIDI DIN output
Values:
OFF = MIDI data arriving at the DIN input will NOT be sent to the DIN output
AUTO = MIDI data arriving at the DIN input will be sent to the DIN output, but ONLY when the RK005 is in ‘stand-alone’ mode
when the RK005 is connected to a host PC (or tablet) there will NOT be any data forwarded from DIN IN –> DIN OUT
(this is to avoid unwanted MIDI loops)
ON = MIDI data arriving at the DIN input will always be forwarded to the DIN output (note this could lead to unwanted MIDI loops!)

Menupage : ‘LED INDICATOR’

Description:
This parameter controls the intensity of the LED indicator
Values:
DIMM = default indicator intensity
BRIGHT = bright intensity
OFF = no indicator at all

FILTERS:

The RK005 can apply up to 4 filters. Each filter can be set to block certain messages (messages which are matched by a filter will be discarded)
In order to define the matching conditions each filter has the following settings:
a) PORT = the ‘connector’ on which the filter should match
b) DIR = the direction for which the filter should match
c) EV = the events for which the filter should match
d) CHN = the channels for which the filter should match (in case ‘channel’ events are used)

Menupage : ‘FLT#1/PORT’

Description:
Determines the I/O port for this filter
Values :
OFF = filter disabled
USB HOST ALL = all devices connected on RK005’s USB-HOST connector
USB OP-1 = OP-1 connected to RK005’s USB-HOST connector
USB CLIENT = RK005’s device connector
MIDI DIN = RK005’s MIDI DIN connectors (IN, OUT or both)

Menupage : ‘FLT#1/DIR’

Description:
Sets the direction of this filter
Values:
RK005 <– * = data flowing into the RK005 RK005 –> * = data flowing out from the RK005
RK005 <-> * = data in one or both directions

Menupage : ‘FLT#1/EV’

Description:
Set the type of events the filter should match
Values:
CHN = channel events
CHN+CLK = channel events or clock
CHN+TRN = channel events or start/stop (=TRaNsport)
CHN+TRN+CLK = channel events or clock / start / stop
ALL = all events

Menupage : ‘FLT#1/CHN1..8’

Description:
Selects which MIDI channels 1..8 for which the filter should match (note: only when EV not set to ‘ALL’ !)
Values:
use buttons 1..8 to toggle channels on/off
this is displayed by the ‘keyboard’ graphic: every ‘red’ bar indicates that the corresponding channel is being matched

Menupage : ‘FLT#1/CHN9..16’

Description:
Select match for MIDI channels 9..16
Values :
See FLT#1/CHN1..8

For menupages FLT#2/xxxx -> see FLT#1/xxxx

note 1) to quickly navigate between filters 1..4 you can press 1,2,3,4 (the big numbers below the display)
note 2) to quickly setup a filter for OP-1 reception or OP-1 transmission: press 1 (labelled ‘IN’) or 2 (labelled ‘OUT’) in the FLT#x/PORT

FLT#x/DIR or FLT#x/EV menu page:
This will pre-set the parameters to form a filter directly for OP-1 transmit or OP-1 receive as a convenience function

Menupage : ‘STORE IN RK005?’

Description:
Use this to make the changes be stored inside RK005’s memory
the settings will be kept, even if the RK005 is disconnected from power

Menupage : ‘RECALL DEFAULTS’

Description:
use this to re-set all parameters to factory default

Menupage : ‘RK005 FW VS’

Description:
Shows the running RK005 firmware version

RK-004 RaspberryPi image

NOTE: THIS IS AN OBSOLETE POST FROM 2017 We have developed the RK006 which is smaller, has more connections/features and does not depend on a RPizero for USB hosting.
For the tinkerer; We’ve released the RaspberryPi image to add MIDI-Host functionality to the RK-004.
