FREQ — Coarse frequency, adjusted by semitone
increments. This control spans 5 octaves. Note that
the
FREQ CV input is normalized to 1⁄12 V, allowing its
attenuverter to be used as a fine frequency control
when no patch cable is inserted.
STRUCT — Harmonic structure. With the modal
resonator, this parameter controls the frequency ratio
between partials (and by doing so, the perceived
structure—plate, bar, string). With the sympathetic
string resonator, this parameter controls the set of
frequency ratios between all strings (with virtual
notches at octaves or fifths). Finally, with the
modulated/inharmonic string resonator, this parameter
controls the amount of modulation and detuning of
the partials.
BRIGHT — Brightness. Adjusts the level of higher
harmonics in the signal, by the simultaneous action of a
low-pass filter on the exciter signal (closed at 8 o’clock,
fully open at 12 o’clock), and the damping filter (or Q
factor of the higher modes) on the rest of the course
of the potentiometer. Low values simulate materials
like wood or nylon. High values simulate materials like
glass or steel.
DAMP — Damping. Controls the decay time of the
sound, from less than 100 ms to about 10 seconds.
