Bass Drum

What it does

808-style analog kick drum synth voice.

Wraps daisysp::AnalogBassDrum. A file-scope prev_trig snapshot detects rising edges — wire a pad to Trig and each press fires once, not every sample.

Parameters

• Freq (Hz)

  freq
  Default 50Range 20 … 400

  Pitch of the drum body in Hz — where the resonator rings after the hit. 50 Hz is a deep 808-style kick; 80–100 Hz cuts through a mix better on small speakers.

• Decay

  decay
  Default 0.5Range 0 … 1

  How long the body rings out. Low values give a tight click-and-gone kick, high values a long boom. Unitless — DaisySP maps 0–1 onto its own decay curve.

• Tone

  tone
  Default 0.5Range 0 … 1

  Amount of click at the very start of the hit — the transient that makes a kick audible on a laptop speaker, separate from the low body that follows it.

• Accent

  accent
  Default 0.5Range 0 … 1

  Overall hit intensity, the way a harder stick strike both raises level and opens the tone. Use it for velocity feel rather than as a volume control.

• Attack FM

  attackFm
  Default 0Range 0 … 1

  How far the pitch sweeps down over the first instant of the hit. A little gives the punch that reads as a kick drum; a lot turns it into a laser zap. Works together with Self FM.

• Self FM

  selfFm
  Default 0Range 0 … 1

  Feeds the drum back into its own pitch, adding grit and a metallic edge. It also alters how the attack sweep and the volume decay behave, so expect it to interact with Attack FM and Decay rather than layer on top of them.

• Infinite Sustain

  sustain
  Default false

  Replaces the decaying hit with a note that rings forever — the drum becomes a tuned sine drone at Freq instead of a percussion voice. Trig no longer restarts anything.
