About the Universal Piston Stepper
The Piston Stepper (also known as the "Piston Sequencer") is an essential tool for organists, enabling them to move through General pistons sequentially, one at a time. The Piston Stepper simplifies performances by automatically advancing memory levels after the highest General piston is pressed. If needed, this action can be reversed by stepping backward.
A Brief History of Piston Levels
Since the 1980s, combination actions introduced Piston Levels, multiplying the number of piston combinations. For instance, with ten General pistons and one hundred levels, organists gained access to 1,000 usable piston combinations. However, navigating these pistons individually during performances proved tedious, and changing piston levels mid-performance added further complications.
The Universal Piston Stepper (UPS) streamlines this process. By pressing the Step-Up piston after the last General piston, the UPS automatically increments to the next memory level and activates the first piston of that level.
Why "Universal"?
Our Stepper earns the title "Universal" thanks to its compatibility with various combination action systems. These systems often differ in voltage and polarity, but the UPS can handle piston voltages from 4.5 to 40 volts DC. The polarity is fully adjustable (negative or positive commons) via the Stepper control board, ensuring a safe installation process—no risk of damage, even with incorrect polarity selection.
Additionally, the UPS employs optical isolation, keeping its logic electrically separate from the combination action system. This ensures seamless operation, as the two systems function independently without interference.
Who Benefits from the Universal Piston Stepper?
Most modern pipe organ control systems already incorporate Piston Steppers, but organs equipped with classic multi‑level combination actions are ideal candidates for our UPS. Without it, the only alternative is replacing the control system computer—a costly and complex solution.
The Universal Piston Stepper offers an efficient and affordable way to integrate piston stepping into classic systems, whether for pipe or electronic organs.
