Other Digital Effects

Other digital effects encompass specialised hardware processors that fall outside standard categories such as reverb, delay and dynamics. As digital signal processing expanded throughout the 1980s and 1990s, manufacturers introduced a wide range of dedicated effects units designed for pitch shifting, harmonisation, filtering and experimental processing.

This archive includes studio digital effects hardware used in professional recording environments. From early pitch processors and harmonisers to specialised multi-function units, these systems reflect the continued evolution of dedicated digital signal processing technology.

Eventide Model H910 Harmonizer®

The Eventide Model H910 Harmonizer was developed by Eventide in 1974. It was the world’s very first digital effects processor. It combined ‘de-glitched’ pitch change with delay and feedback. It could be controlled by a keyboard remote control to instantly shift pitch in half steps.

MXR Model 129 Pitch Transposer

The MXR Model 129 Pitch Transposer is a classic piece of audio equipment that was released in the late 1970s. The unit was designed to allow musicians and audio engineers to transpose the pitch of audio signals up or down by a fixed amount, ranging from one octave below to one octave above the original pitch.

Eventide Model H949 Harmonizer®

The Eventide Model H949 Harmonizer is a combination digital delay line, pitch changer, and all-round special effects unit. The TIME REVERSAL feature is entirely new. When used with a variable-speed tape recorder, the Harmonizer is capable of shortening or lengthening a piece of program material to fit a given time slot, without altering the pitch.

Roland DC-50 Digital Chorus

The Roland DC-50 Digital Chorus, released in 1978, is a desktop chorus and hall echo unit combining warm analogue BBD chorus with early digital echo. Designed for vocals and instruments, it offers simple controls, flexible inputs, and a rich, spacious sound that remains sought after for its classic late-70s Roland character.

Publison DHM 89 B2 Stereo Digital Audio Computer

Introduced in 1978, the Publison DHM 89 B2 Stereo Digital Audio Computer was a dual-channel French digital processor combining delay, echo, pitch-shifting, reverse playback, sound-memory looping and external control. Its quasi-16-bit flying-comma conversion system operated at a 52.91kHz sampling frequency, while 210kbits of RAM provided selectable delay times at frequency responses of 5kHz, 10kHz or 20kHz.

Publison Infernal Machine 90 Stereo Audio Computer

The Publison Infernal Machine 90 Stereo Audio Computer was a French 16-bit dual-channel digital processor introduced in 1984. It combined delay, echo, independent pitch-shifting, stereo reverberation, sampling, time compression and time expansion in a programmable and expandable system. MIDI, optional SMPTE/EBU synchronisation, computer control, digital audio interfacing and a dedicated remote allowed the Publison Infernal Machine 90 to operate as both a studio effects processor and an early digital audio workstation.

Eventide Model H969 Harmonizer®

Eventide’s newest Harmonizer in 1985 was the Eventide Model H969, which expanded on Eventide’s already capable Eventide Model H949 Harmonizer. The Eventide Model H969’s new ProPitch digital electronic-splicing algorithm gives you the cleanest, most glitch-free pitch change ever. Deglitching is active over a wider bandwidth, too – a full octave wider.

Yamaha SPX90II Multi-Effects Processor

The Yamaha SPX 90 II was essentially the original SPX 90 with more memory added to improve delay times, and they gave it a new look with green button surrounds. Regardless of the fact that the SPX 90 II is the exact same effect processor as the SPX 90 only with increased memory for longer delay times, it sells for much less. Bargain hunters rejoice!
