Slew Over is a free slew limiter from Florian Mrugalla that caps how fast the waveform can change, set in pitch or Hz, with low-pass or high-pass modes and optional 2x oversampling.
It is free and open source (GPL 3), as VST3 for Windows.
Best for: Keys & Synths, Bass, Drums, Sound Design. Genres: Electronic & EDM, Lo-Fi.

What it does
Slew Over is a small free slew limiter, described as "a simple slew limiter with oversampling." A slew limiter caps how fast the signal can change, which acts like a filter whose effect depends on level, so it sits between filtering and distortion. The developer made it while analysing the spectral response of slew limiters.
- Slew: sets the maximum rate of change, shown as an approximate pitch or frequency in Hz.
- Filter type: switches between low-pass and high-pass behaviour.
- Gain Out: output level, to make up for level lost in processing.
- HQ mode: optional 2x oversampling to reduce aliasing.
Version 1.0 is free and open source under the GPL 3 license; the source is on GitHub.

When to use it
Slew Over is for when you want to soften or brighten a sound in a nonlinear way that reacts to level, which a normal filter does not do. Compared with Volcano 3 or FilterFreak, it has no modulation, resonance or multiple filter shapes, just one slew control and a low-pass or high-pass switch, but it costs nothing and gives a different, slightly distorted character. Louder, faster-moving material is affected more, so it can tame harsh transients or edgy synths differently from an EQ. It is an experimental tool rather than a full filter.
- Best for: rounding off harsh synths, bass and drums, or sound design where level-dependent tone change is wanted.
- Genres: electronic, experimental and lo-fi.
- Look elsewhere if: you need a standard, predictable tone filter with modulation (Volcano 3 or FilterFreak).
