Every command surface an organist needs—from the rocker tabs above the keyboards to the toe pistons beneath the pedalboard. Modular, affordable, and beautifully functional.
The OpenPipes legacy peripheral system is designed to be modular. Each peripheral board connects to the Main MIDI Controller via simple ribbon cables, and multiple boards can be daisy-chained to build consoles of any size.

Rocker Buttons
Toggle-style stop controls that mimic traditional organ rocker tabs. Each board supports multiple channels for rank selection and coupler activation.
Thumb Buttons
Compact momentary buttons mounted below the manuals for combination memory, general pistons, and preset recall.

Push-and-Pull Knobs
Traditional drawknob-style stop controls for a classic console aesthetic. Each knob sends a MIDI on/off message when engaged or disengaged.

Volume & Expression Pedals
Analog expression pedals for controlling swell box dynamics and overall volume. Connects to the controller's analog inputs for smooth, continuous control.

MIDI Keyboard Encoder
Converts standard keyboard matrix signals into MIDI note messages. Enables the use of salvaged or affordable keyboards in your console build.

Analog Sliders
Linear faders for mixing and volume control. Perfect for configuring audio levels across multiple divisions or channels.
