mod_adsr_a10ms_d100ms_s0_70_r200ms
ADSR envelope (A=10 ms, D=100 ms, S=0.70, R=200 ms) applied to a 220 Hz sine.
Expression: (impulse() >> adsr_live(0.01, 0.10, 0.70, 0.20)) * sine_hz::<f32>(220.0)
mod_lfo
Exponential-decaying frequency LFO (native generator).
Expression: lfo(|t: f32| exp(-t))
mod_sample_hold_5hz_var0_2
Stepped random control source: hold_hz(5 Hz, variability 0.2) internally generates new levels every 200 ms.
Expression: hold_hz(5.0, 0.2)
mod_follow_attack100ms
Amplitude follower: tracks a slowly modulated 220 Hz source (2 Hz depth 50%). Attack ≈100 ms. Chart includes input & follower output for comparison.
Expression: (sine_hz::<f32>(220.0) * (1.0 + 0.5 * sine_hz::<f32>(2.0))) >> follow(0.10)
