Trumpet
the trumpet. The timbre of the noise is controlled by a resonant bandpass filter, and
there is a dedicated ramp envelope to control the level of the noise (for creating
attack sounds).
Gain
0.0-100.0. This is the maximum breath level, scaled by the Breath Pressure section's
Pressure and Pressure Mod parameters.
Frequency
0-24000Hz. The tone of the breath noise is shaped by a bandpass filter. This controls
the center frequency of that filter.
Resonance
0-100. This controls the resonance of the filter. At 0, the filter will not resonate at all;
at 100, it will be very resonant.
Ramp Amt
0-100. This sets the amount by which the ramp envelope (controlled by Ramp
Decay, below) affects the volume level of the breath noise.
Ramp Decay
0-100. This sets the decay time of the ramp envelope.
Output
Volume
0.0-100.0. This is the output volume for the trumpet. It has extra smoothing on the
DSP, to ensure zipper-free modulation. If you want to modulate the volume
instantaneously via velocity, use the Vel Sens control instead.
Vel Sens (Velocity Sensitivity)
0-100. This sets the sensitivity of output volume to velocity. A velocity of 127 will
always result in the maximum output level, as set by the Volume control; increasing
the Vel Sens will decrease the output volume for low velocities.
Bell
The bell affects the sound in two ways: by feeding back into the body of the
instrument, and by shaping the timbre of the sound output. The highpass and
lowpass filters, below, affect the output timbre.
Highpass
0.00-100.00. This controls the cutoff frequency of the highpass filter. Frequencies
below the cutoff will be attenuated, and frequencies above the cutoff will pass
through unchanged.
