Five new synth waveforms: tape-replay Mellotron (strings/flute/choir tapes with wow, flutter, saturation, 8s fadeout), hard sync oscillator, ring modulation, wavefolding, and analog drift VCO with pitch instability. 14 new instrument presets for Score.part(). Synth kwargs now pass through play()/save()/_render(). 808 bass envelope fixed from pluck to piano. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
