Synth voice — osc × ADSR through envelope-scaled lowpass (Tone.js Synth class)
Osc + envelope voice (Tone.js Synth class)
import voice from '@audio/synth-voice'
Composed voice — synth-osc through a one-pole lowpass whose cutoff is scaled by an synth-envelope ADSR, the Tone.js Synth/MonoSynth class. Pitched — (freq, opts).
