How to Set up Lemur with REAKTOR 5.8 or Higher (OS X)

Since REAKTOR 5.8, establishing an OSC connection with third-party controllers has been simplified for better ease of use. This article will explain how to establish a Lemur connection via a local network on a Mac for use with REAKTOR 5.8.

Create a Local Network

First of all, click on the network icon from the Menu bar top right of the screen.
Select Create Network from the drop-down menu.
Choose a Network Name. In this example the name is clem.

Join the Network with your iPad

On your iPad go to Settings > Wi-Fi and look for your network name. Click on it to join it.
Click on the right arrow to see its properties. After a few seconds the IP Address should appear. Make a note of the 12 digit number, which should begin with 169.254.... You will need to enter this number further along in this tutorial.

REAKTOR 5 OSC Settings

Open REAKTOR 5. Click on File>OSC settings. Make sure the box next to OSC Activate is checked and that Receive on Port is set to 10000.
Click on the OSC Send tab.
Create a new OSC Target by clicking on New. In the Identifier column rename the newly created default entry to iPad. Under IP Address enter the number you made a note of earlier on in the tutorial. Set the Port to 8000.

Setting up Lemur on your iPad

Open Lemur.
In the Preferences screen go to the OSC Targets list.
Click on Add Target.
Set Host to your local IP address as given under Reaktor > Preferences > OSC settings > OSC Receive > Local IP address name and set the Port to 10000.

Note: In the Lemur software you cannot set the incoming OSC port. It is always set to 8000.
In the Lemur Preferences load any layout (eg. Studio Combo).
Go back to Reaktor OSC Settings and click on OSC Receive. Move any slider on Lemur. A list of data messages should appear.
In REAKTOR 5 open a new ensemble and create an instrument. Add a Knob.
Open its Properties (right-click on the icon and select Properties).
Click on the Connect tab. Under MIDI & OSC CONNECTIONS select OSC SEND.
Click on Add Target and select iPad.
Now it is necessary to set the Address Pattern so that it matches one of the Lemur objects address patterns. The easiest to do this is to move a slider on your iPad and check which name appears in REAKTOR's OSC RCV tab. Say we move Fader1 in the Studio Combo template. Incoming messages will look like /Fader1/x 0.5264. Copy and paste /Fader1/x into the Address Pattern area under OSC SEND so that it looks as such:
Now move the Knob in REAKTOR 5. The first fader in the Lemur software will move.
