After more then 2 years of work together with LPZW modules, we are very happy to finally reveal out next eurorack module on 13th of September 2021.
We will present and show the module at Superbooth. Visit us at our booth and check out the presentation on Thursday, 16th !
Here is a manual describing how to install our uniPulse midi interface in an
Elka “The Sidekick 32” drum machine.
This manual describes how to use and install the uniPulse midi interface in a Hohner Rhythm 80 drum machine.
Installation requires soldering some wires and drilling holes for the midi socket. However no need to cut any traces.
After installation you will be able to trigger all sounds via midi, most velocity sensitive.
Unplug the Rhythm 80 when working on it!
After opening up the enclosure, you are presented with the following view of the boards:
Our uniPulse universal midi interface can be installed in a Roland CR-68 and will add the following features:
– Velocity sensitive trigger of all instruments
– Global Accent trigger with the existing accent amount control
– Midi clock sync and start/Stop
This manual describes how to install our uniPulse midi retrofit in a Hohner Automatic Rhythm Player.
After installation you will be able to trigger all 10 sounds, most of them fully velocity sensitive. You will not be able to sync the internal rhythms to midi clock however.
Soldering pulse triggers
Installation is fairly simply and requires you to solder 10 wires from uniPulse to points on the Rhythm Player voice board. These are P1-10 and CV (as labelled on the back of the uniPulse board). The black P7 wire is not used.
Unplug the machine, remove the slotted screws and open it. Then solder the wires as shown in the following pictures. The “CV” connection used for the Maracas needs an additional diode. Any Diode is fine here. As you can see, the cathode of the diode (marking) connects to the cathode of the existing diode.
INstalling the midi socket
In order to install the midi socket you need to drill 3 holes. A stencil for drilling is provided. For the large hole you can use a stepping drill. Now mount the socket using the screws provided.
Mounting the unipulse board
You can mount the uniPulse board anywhere in the machine. We decided to use thick double sided tape to mount it on the rear. Make sure the board can not short to the metal chassis.
After installation, plug in the machine and turn it on. The LED on the uniPulse board should light up indicating proper power connection. Using the uniPulse configurator tool, upload config file for the Hohner Rhythm Player (zipped, extract before opening in the configurator)
That’s it! have fun!
The incredible Sunshine Jones took our Juno-66 user manual, improved the design and added more info for clarity.
The result can be found on his website. There is also a nice cheat sheet you should not miss.
Additionally he made a few short video demos of specific Juno-66 demos:
Arp and Powerarp
Chord Memory and Polychord
This is how to open our Firmware updater utility on OSX. This should work with any other unsigned app as well. This has been tested with OSX Big Sur but probably works with older OSX versions as well.
Download the app. Safari will place it in the Dowload folder. Navigate to the Download folder in Finder.
Right click on the file and select “new Terminal at Folder”
A terminal window opens. Type the following command: (you can copy and paste it here)
sudo chmod -R 755 ./
You will be promted for your password. Enter your password – it will not be visible. After entering your password press enter.
Open the folder with the little arrow on the left, right click on the “Tubbutec Firmware Updater” application and select “Open”
You will see a message that the file can not be opened. Click Cancel.
Repeat step 3! The second time you click open, the following window will appear.
Click Open and the app will start 🙂

A second USB Bridge A is used to connect a USB midi keyboard directly to the Novation Peak.
In depth review of Tubbutec µTune and expander by Synth DIY Guy
He used the Linnstrument in MPE mode to microtonally control his modular setup and show a lot of µTune’s features.
