The Publison Infernal Machine 90 is a digital signal processor that was first introduced in 1984. It was designed to offer a range of sophisticated audio processing capabilities, including pitch-shifting, time-stretching, and digital filtering.
One of the most notable features of the Publison Infernal Machine 90 was its ability to create complex harmonies and modulations. This was achieved through the use of a unique algorithm that allowed users to create harmonies based on the ratios of the frequencies of the input signal. This algorithm was highly innovative at the time, and it helped to establish the Publison Infernal Machine 90 as a highly sought-after piece of equipment in the music industry.
The Infernal Machine 90 was also notable for its use of a custom-designed digital signal processor, which offered high levels of processing power and a high degree of flexibility. This made it possible for users to create a wide range of different effects and processing chains, including advanced delay and echo effects, flanging and phasing, and dynamic processing such as compression and gating.
One of the key advantages of the Infernal Machine 90 was its ability to process audio in real time, which made it well-suited for use in live performance and recording applications. Its high degree of flexibility and customisation also made it popular among studio producers and sound engineers, who used it to create unique and innovative sounds for a wide range of musical genres.
The Publison Infernal Machine 90 was used by a number of notable artists and producers, including Brian Eno, Frank Zappa, and Pink Floyd. Its unique sound and advanced processing capabilities helped to shape the sound of popular music in the 1980s and beyond.
The Publison Infernal Machine 90 boasted an impressive array of effects, from standard audio processing tools like reverb, delay, and chorus to more exotic and unique effects such as granular synthesis, pitch shifting, and spectral processing. Its programmability and automation capabilities set it apart from any of its analogue counterparts.
Publison Infernal Machine 90 users could save and recall presets, simplifying the reproduction of specific effects or configurations. It could also be seamlessly integrated into existing studio setups and controlled via MIDI, allowing for automation and synchronization with other MIDI-compatible equipment.
The Publison Infernal Machine 90 remains a highly sought-after piece of equipment among collectors and enthusiasts. Its impact on the music industry and the development of digital signal processing technology cannot be overstated, and it continues to be celebrated for its innovative design and unique sound.
