Sound and Output Stage Design
Resonance-style limiters often leave a harsh edge at high gain, but McDSP uses a custom output stage topology on all Retro plugins to eliminate digital clipping at any output level. The developer says this produces a smoother distortion character.
Alongside that output stage, the 4040 includes analog saturation modeling, a feature McDSP has built its reputation on. The algorithms are described as original and transparent, with a vintage quality rather than an emulation of a specific unit.
The plugin offers up to 36 dB of signal gain and uses zero latency algorithms with double precision processing.
