Feature Reference
Signal Select
≤
Normal, Breath Noise Amp., Flow Rate Saturation, Beat, Slit/Friction, Reed.
Selects the signal to be used by the carrier or modulator.
This is the total output of the instrument model: a mix of the driver,
Normal
pipe/string, and tap signals.
This signal represents the instantaneous amplitude of the breath noise
Breath Noise
produced at the driver. It is basically a highly distortion version of the
Amplitude
Slit/Friction signal described below.
When the pressures on either side of an aperture (e.g. a mounthpiece/
reed assembly) differ, a corresponding flow of air is produced. There is,
Flow Rate Satura-
however, a limit to the speed of the airflow which can be produced
tion
(saturation). The relationship between the pressure difference and
resulting airflow is derived as the Flow Rate Saturation signal.
The beat signal represents contact between the vibrating reed and the
Beat
mouthpiece.
As the reed vibrates, the area of gap (slit) between it and the mouth-
piece varies accordingly. The Slit/Friction signal corresponds to the
Slit/Friction
varying are of the reed/mouthpiece slit.
This signal is derived directly from the flexing of the reed.
Reed
HPF Cutoff
≤
17.0 Hz ... 11.2 kHz.
Both the modulator and carrier blocks have high-pass filters that can be used to roll
off the low frequencies of the corresponding signal. This parameter sets the cutoff fre-
quency of the carrier or modulator high-pass filter.
Over Drive
≤
0.063 ... 15.31.
This parameter boosts the corresponding modulator or carrier signal, forcing it into
distortion and thereby drastically changing its harmonic structure. The higher the value
the greater the distortion. No distortion is produced below a setting of "1.0".
Level (Carrier only)
≤
0 ... 127.
Sets the output level of the carrier. The higher the value the greater the output level.
Balance
≤
-64 ... 63.
Sets the balance between the "wet" (the output of the harmonic enhancer) and "dry"
(the direct signal) signals. The higher the value the more "wet" the signal, and therefore
the more pronounced the harmonic enhancer effect. The carrier and modulator page
"Balance" parameters are linked.
