The OhmRGB is a hardware MIDI controller from Livid Instruments for DJs and VJs with a nice mix of faders, knobs and buttons for triggering clips or FX. It's an especially useful controller to use with VDMX because it has a versatile layout which can be adapted for a variety of different setups ranging from simple DJ style two channel video mixers to advanced multiple layer compositions. 

This first basic example template turns your Mac into a simple two channel HD video mixer VJ setup controlled by the OhmRGM Slim controller. It makes use of MIDI talk-back to light up the buttons along with the media bin and is set up FX chains and 6 different composition modes. This starting point leaves all of the knobs on the controller available for further customization with your own video clips, FX and LFOs.

If you don't have an Ohm, this example VDMX setup also includes a control surface layouts to mimic the hardware so you can still try out the mixer and synth parts of the sample projects.

 For this template the assignments are pretty straight forward - the main button grid is used to trigger movies in the left / right media bins, the crossfader is used for mixing, the faders / fader buttons are used for left / right FX and the top-right buttons are used for switching composition modes.

To get some more use out of MIDI feedback with the OhmRGB, here are two useful tricks to try out when creating your own templates.


Send the value of the Two Channel Mixer crossfader in VDMX out by MIDI to change the colors of the XL and XR buttons on the Ohm.

Send the 'Every Beat' value from the Clock plugin to the button on the controller used for tap tempo to visualize the current clock rate.
