Pulsar
Stereo delay with per-channel pre-delay, filtering, and internal LFO modulation. Build large stereo spaces with rhythmic movement.
Rasselbock
Resampler with sequencer grid and seven built-in effects. Route through one master or separate per effect outs, reverse, pitch shift, and create experimental patterns.
Helmholtz
Comb filter with five tuneable resonant frequencies. Creates dramatic resonances, especially reactive to noise and impulsive inputs.
Gravity
Single-band compressor with visual feedback and gain reduction meter. Control threshold, ratio, knee, attack, and release with RMS or peak detection.
Quantum
Multi-band compressor designed for mastering. Four bands with adjustable crossovers, per-band bypass/mute/solo, and spectrum analyser.
Orbit
2-band EQ with spatial control of the stereo field.
AutoFilter
Dynamic filter driven by an envelope follower or sidechain input. Creates rhythmic movement and ducking effects automatically.
Exciter
Spectral enhancer that splits the signal into bands, applies distortion to higher frequencies, then recombines. Add presence and clarity to your tracks.
Panorama
Independent left/right pan and level controls for fixing imbalances and designing stereo movement.
Ring Modulator
Multiplies two signals to produce metallic or robotic timbres. Perfect for experimental textures and robotic sounds.
Stereo Enhancer
Widen the stereo field and enhance spatial perception in your mix or master output.
WaveShaper
Drawable transfer curve for designing distortion with precise control over harmonic content. Perfect for unique distortion shapes and extreme sound design.
