Airflow
Technology

The Orchestrionix IPU-system heralds a groundbreaking era in pipe organ music. Harnessing the age-old principle of air dynamics, we’ve innovated an unprecedented level of airflow control, unlocking richer, more nuanced sounds and performance capabilities. No longer are organs constrained by traditional limitations. With the IPU-system, experience a symphony of precise controls, dynamic mastery, and transformative organ expressions.

Redefining Musical Potential

Air flows from high to low pressure, a principle used for millennia in music-making. Since the first bone flute, this has shaped musical sounds. Orchestrionix introduces the IPU-system, leveraging DECAP airflow systems for pipe chests and accordions, revolutionizing pipe organ capabilities and ushering in a new era of organ music.

Real-time Precision

Speed and accuracy are the backbone of the IPU system. Airflow to each individual pipe is adjusted at a rate of +1,000 times each second to achieve a real-time response ranging from 0 to 200% air pressure, where 100% is the pressure used during the voicing of the pipe. This “100%” can be adjusted for each individual pipe at any time. This means that every pipe can be set to its own pressure without any limitation. If 100mmWc is the goal, but one pipe sounds more in balance at 99mmWc, then a simple click of a button stores this 99mmWc preference in the EEPROM memory for as long as you do not change it as the required pressure for this pipe. 100% then refers to 99mmWc, and 200% to (x2 99=) 198mmWc

 

Stability & Versatility

Beyond its artistic prowess, the IPU system is designed with robustness in mind. Real-time PID-feedback-loop regulation means that the sound remains consistent at all times, irrespective of external factors. Thanks to +100 years of experience of our organs playing in the most extreme situations (-10 to +30°C humid and nicotine-saturated air in every week transported mirror palaces), we understand the conditions organs have to perform in.

Airflow Technology in action

We had the pleasure of utilizing this new technology in a couple of new projects. 

Technical Deep Dive

High-Frequency Airflow Adjustments

Gain unparalleled control with millisecond airflow-update-timing resolution, adjusting over 1,000 times per second within a 0 to 200% pressure range, all settable via any MIDI controller.

Dynamic Mastery with MIDI

Integrate effortlessly with any MIDI controller – pedals, wheels, key velocity, or even DAW control curves, for detailed airflow control.

Real-Time PID Feedback Loop

Maintain sound consistency regardless of external factors. The PID-feedback system provides organists with consistent and dependable sound output.

Variable Pressure Customization

Individually calibrate each pipe’s pressure on-the-fly using a slider, replacing traditional foot pressure screws. Whether targeting 100mmWc or a nuanced 99mmWc, settings are stored in eeprom memory, automatically fine-tuning the system’s reference.

Automated LFO Effects

Experience advanced effects like “spitting” in the pipe and intricate vibratos. The “Automated Low-Frequency-Oscillator” (LFO) offers customizable parameters in terms of income, speed, depth, and decay.

SLOPE & VIBRATO 1&2

Achieve nuanced airflow control at a note’s onset with the SLOPE for a gradual soft to aggressive attack. Benefit from dual dynamic sinus wave airflow (VIBRATO 1&2) throughout the note’s duration.
