How it's made
Source
four open strings plucked at 0.12, 2.08, 4.12 and 6.04 s in a repeating 8 s cycle. The tuning is fifth, upper tonic, upper tonic, lower tonic; a 4-8 ms release softens the attack.
Body
each string has 16 harmonic displacement modes shaped by a pluck point at 0.19 of its length. Fundamental T60 is 7-12 s; frequency-dependent losses shorten the highest modes to 1.0-2.2 s.
Bridge
weak upper harmonics bloom over 55 ms as the string grazes the bridge, then decay in 1-3 s. Two quiet, damped soundboard modes at 1.13 and 2.73 times the tonic ring for 0.18 and 0.12 s.
Envelope
periodic impulse-response sums include three preceding cycles, so ringing is present at t=0. Successive plucks overlap; no room reverb or continuous synthetic pad is added.
Variation
seeded phases and course strengths stay fixed each cycle; paired upper tonic strings differ by 0.125 Hz for slow beating. Root pitch, damping, bridge brightness and stereo spread are adjustable.
Presets
warm balanced practice, bright bridge-rich shimmer, low dark grounding, and a light upper drone.
