Expression Block

The Expression Block controller produces a voltage as you press the block down, similar to the Ondes Martenot and other instruments. The Expression Block is perfect for controlling amplitude/volume as you play notes on the keyboard, or to control filter frequency or other parameters.

The Q181EB is a single-space module so it can be mounted anywhere in a system or in a Box cabinet next to your keyboard and other controllers.

The Expression Block controller uses our standardized Q181 single-channel controller interface module providing an Auto Gate, Switch Gate and a voltage output preset switch.
