10: Brass Model
This oscillator is a physical model which simulates lip-reed instruments such as a trumpet or trombone.
By using key velocity or modulation wheel to modulate the Pressure (the force of breath blown into
the mouthpiece) you can produce performance expressions that are very similar to those of an actual
lip-reed instrument. The parameters are as follows: Inst Type determines the model which simulates
the bore length and shape of the instrument, Breath Pressure indicates the force of breath that is
blown into the mouthpiece, Lip Character produces the tonal changes that result from lip position or
tension, Bell Character produces the tonal changes that result from the shape of the end of the bore,
and Peaking EQ performs a final tonal adjustment.

This oscillator allows you to choose from two types of pitch bending: jump bending using a mode
jump as on a trumpet (by varying the bore length), and smooth bending produced by sliding the
length of the bore as on a trombone.
For some parameter settings, the pitch may not change according to the notes that are played on the keyboard.
In some cases, high-pitched notes may have a lower volume, or may not sound at all.
