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.

Sony DPS-M7 Sonic Modulator

After a digital reverb and a digital delay, the next logical choice for Sony was a modulation processor, and that is exactly what they delivered with the Sony DPS-M7. With the new Sony DPS-M7, Sony continued to improve the sonic characteristics of the internals, with the DPS-M7 showing even better noise floor performance than even the DPS-D7 that preceded it.

Sony DPS-F7 Dynamic Filter Plus

After the digital reverb, digital delay and then a modulation processor, what could Sony release next? A dynamic filter, which lacked the appeal of the first three effects in the DPS line up. The Sony DPS-F7 is suited to keyboard players more so than studios, as it generates rather interesting effects for keyboards including vocoder and synthesiser. Having said that, creative engineers could find great use for this effect in their racks.

Ensoniq DP/4 Parallel Effects Processor

Ensoniq were a keyboard manufacturer back in the 1980s, but their legacy seems destined to be their first multi-effect processor, the Ensoniq DP/4. Using their experience from keyboards and samplers, Ensoniq developed their first effects processor in 1992 towards the end of their keyboard era, and to this day, the Ensoniq DP/4 is still being sought after.
