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.
Voltage Output Presets
The main output of the Q181EB Expression Block Controller is a voltage that varies as the block is pressed.
The range of the output voltage is controlled by the Output Range Preset switch to select 5 volts, 2 volts or 4/12ths volt.
For modulation, use the 5 volt position then attenuate or invert the signal at the destination module.
Auto Gate
An Auto Gate signal is created as the block is pressed.
The position at which this Gate is produced is set with the Auto Gate control knob.
This Gate can be used to start Sequencers, trigger Envelope Generators or to change parameters in the system.
Switch Gate
At the bottom of the block's travel is a switch that activates a Switch Gate signal.
This is just like any other Gate and can be used to control Sequencers and Envelope Generators.
The Switch Gate can also be activated manually with the panel button.
LED Colors
A programmable 3-color LED lights the acrylic block.
The LED can be programmed to change colors as the block moves.
It can also stay a solid color, or change color as the Auto Gate triggers.
These settings are made using a jumper array on the circuit board.
