The reference synthesiser gains what a short channel sting needs, all in the wai.det.fixed64 floor and trig-free, every committed score rendering byte for byte as before (the three first-revision vectors keep their mixdown hash, PCM SHA-256 and score hash): - score §2.2, §3.1: waveforms 4 to 6, the saw, square and 25 %-pulse with each step corrected by a polynomial (PolyBLEP); 7, a sine by a refined parabola; 8, noise held from a 32-bit LCG between wraps of the phase. - score §2.1, §3.4: a contract of two channels mixes down to interleaved frames; a reader refuses any count but 1 and 2; a score with no voices centres each note. - score §2.4, §3.3: an optional third section, one 73-byte voice per note: a constant-power pan by the profile's integer square root, curved attack, decay and release (the release from the level at note-off), up to four one-pole low-pass sections that follow the envelope, a linear glide, the noise seed, and up to eight echoes at alternating pans. The 65-byte note record is unchanged; the score hash binds the voices when present. - wai score build|render: channels 2, waveforms to 8, each note's optional voice; render prints frames and channels. Receipt blocks are 4096 frames. - score-conformance: five vectors at 48 kHz (band-limited, two channels, voiced in one, a two-second sting, a voiced scale); multi_verify.py's independent synth agrees with all eight. - packaging §5.8: a score of one or two channels packs beside the lead with its voices, its floor the FLAC of the mixdown in its channels; verify holds the floor to the base's channels and rate. pack-conformance/multi/multi-sting-01 is a voiced two-channel score at 48 kHz. - The composing sink synthesises and plays a score in its contract's channels; its reference package's score is now two channels at 48 kHz, voiced.
