bend-in = every note starts flat by bend cents and reaches pitch after bend time along (1−x)^curve (1 = linear rise, 3 = fast start); low reeds add low cents / low time, fully from top − span down, nothing at top; from silence both scale by silent ×. attack ≥ periods cycles of the lowest reed. open: on low reeds the lowpass starts at start harmonic × f0 and opens over open time (the 1–2 kHz formant arriving late). late fundamental: the fundamental starts that many dB down and fills in over its time; mid bump: the harmonics around mid bump harmonic × f0 start that many dB hot and relax over its time (both weighted like the bend's low extra; the bump's centre harmonic is read when the note starts). timbre: steady trims read at note start — a high shelf (dB, from Hz) over the top harmonics, a midrange peak/cut (dB, centre Hz, width Q) and a boost/cut on the fundamental; "low reeds only" weights them like the bend's low extra.
