Released in 1992
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.
