k2k audio Parameters
| Parameter | Range | Default |
|---|---|---|
| Horn Level | 0.0 – 1.0 | 0.8 |
| Drum Level | 0.0 – 1.0 | 0.6 |
| Speed Fine | 0.5 – 2.0 | 1.0 |
| Dry/Wet | 0.0 – 1.0 | 1.0 |
Horn Level — Level of the horn (high-frequency rotating speaker), 0–1. The Leslie cabinet has two rotating elements: a horn for highs and a drum for lows. This sets the horn’s contribution to the output. 0 silences the horn entirely; 1 is full level. Typical use: 0.7–0.9 for the bright, treble-rotation sound. Pair with drum_level to balance the two rotors.
Drum Level — Level of the drum (low-frequency rotating speaker), 0–1. Sets the bass rotor’s contribution. 0 silences the drum; 1 is full level. The drum produces the bass rotation that gives Leslie its full-bodied character. Typical use: 0.5–0.8.
Speed Fine — Fine-tune adjustment to the rotor speeds, 0.5×–2.0×. Acts as a multiplier on top of the speed mode (Slow/Fast). 1.0× is unmodified. Use this to dial in the exact speed feel — slightly faster than slow for “warm chorale,” slightly slower than fast for a more deliberate tremolo.
Dry/Wet — Equal-power blend between dry (0) and Leslie output (1).
Additional controls
Speed — Rotor speed mode:
- Slow — chorale (~40 RPM rough equivalent); slow rotation, lush chorus-like character. Used for sustained chords, pads, organ vibes.
- Fast — tremolo (~340 RPM); fast rotation, pulsing tremolo-like character. Used for solo passages, intense moments, organ leads.
Real Leslie cabinets ramp between speeds when switched — that gradual ramp is what makes Leslie effects so musical. (K2K’s Leslie may or may not include the ramp depending on the implementation; behavior may match real Leslies exactly.)
About Leslie
The Leslie speaker cabinet (originally designed by Don Leslie in the 1940s) was the iconic partner to the Hammond B3 organ. Inside the cabinet, sound is routed to two rotating speakers — a horn for highs (rotating one direction) and a drum for lows (rotating the other) — producing complex Doppler shifts, phase modulations, and amplitude variations as they spin. The result is a richer, more dimensional sound than any simple chorus or tremolo can produce. Use it for: organ-style modulation on any source (works beautifully on guitars, vocals, synth pads), classic rock-organ vibe, or rich vibrato that goes beyond what simple LFO modulation can produce. Pair with the Native Distortion or Saturator for full “B3 through a cranked Leslie” character.
