Ithaca, Two Ways to Make a Piano Speak

Field notes

Legacy separates sample playback from synthesis: it keeps sample heads in memory and streams the remainder from disk, while its audio thread is described as lock-free, allocation-free, and isolated from disk access. The page also specifies measured peak-based velocity mapping, continuous sustain-pedal behavior, and sympathetic resonance. macOS is the only platform reported as verified; the first content bank, recorded from a historical Petrof, remains in progress.
