Rave Generation Knock

The ultimate techno bassdrum synthesizer. Circuit-accurate 909 core, six transient characters, sample layer, allpass dispersion, full strip EQ, and per-hit modulation. From house kicks to gabber bassdrums in one plugin.

• Circuit-accurate 909 core
Hardware-measured TR-909 bassdrum with triangle oscillator, LFSR noise click, diode clipping, transistor VCA, and RC envelopes.
• Dual oscillator modes
Classic (authentic 909 triangle with asymmetry and rounding) and ALT (SVF bridged-T network for a cleaner, resonant tone). Both respond to the same pitch, sweep, and waveshaping controls.
• Independent Sweep Depth
Separate control over pitch sweep amount (0-600 Hz), independent from sweep time. At 0% there is no pitch drop (pure sub). At 33% it matches the original 909. Crank it for laser territory.
• Body Waveshaper
Continuous waveshaper that morphs the oscillator from pure sine to parabolic, adding warm even harmonics (2nd harmonic) that fatten and thicken the kick body without adding the mud of a standard saturator.
• Six tick transient types
Classic (2kHz sine burst), FM (metallic FM impulse), Noise (filtered noise burst for airy presence), HP (highpass-filtered), Chirp (fast pitch-swept electronic zap), and Metal (inharmonic bell partials for industrial texture).
• Dedicated Punch FX section
Time-windowed transient processor with four filter types (LP/HP/BP), four distortion algorithms (Tube/Tape/Clip/Fold), tone shaping, and a wet/dry mix - all applied only to the transient zone of the kick for surgical attack control.
• Sample Layer
One-shot sample player with 50 embedded samples (attacks, clicks, punches) for layering on top of the synthesized kick. Includes pitch shifting (±24 st), decay envelope, highpass and lowpass filters, timing offset, phase flip, velocity sensitivity, and a pitch bend (pogo) envelope. Configurable Strip EQ routing lets the sample bypass, share clean EQ, receive modulated EQ, or pass through the full gain + EQ chain.
• Disperse
Allpass cascade engine with up to 256 second-order allpass filter stages for transient smearing and laser sweep effects. Controls for center frequency (20-5000 Hz), stage count, pinch (Q), frequency spread, and dry/wet mix. Selectable Pre or Post signal chain position - Pre for smoother musical sweeps, Post for grittier dispersion after drive.
• Strip EQ
Full channel strip with 0-40 dB gain (with analog console saturation), dual parametric mid bands with adjustable frequency and Q, high and low shelving EQ (±15 dB), and an 18 dB/oct highpass filter with adjustable frequency (5-200 Hz) and selectable Pre/Post gain routing.
• Mod Ring
Per-hit envelope modulation system that dynamically shapes the Strip EQ and reverb send on every trigger. Five envelope shapes (Exp, Lin, Log, Bump, Sine) with independent depth controls for Lo-Mid gain, Hi-Mid gain, Lo-Mid frequency, Hi-Mid frequency, strip gain, send level, high shelf, and low shelf. Create transient EQ sweeps, per-hit gain boosts, and rhythmic tonal movement without automation.
• One-knob output drive
Warm tube-like saturation with asymmetric soft clipping, plus independent HI MID and HIGH coloration controls for final tonal sculpting.
• Built-in reverb send
Nine reverb modes (Room, Hall, Plate, Multi-Tap, Gated) with pre-delay, tone shaping, drive on the wet signal, and three tail modes: Off (natural ring), Reset (clean per hit), or Duck (sidechain pumping effect).
• Clip 0dB protection
Two-stage soft-knee limiter + hard clip for transparent output limiting without audible artifacts.
