DESCRIPTION

Audio output is a tone related to a brass instrument, using a physical model  developed from Perry Cook, but re-coded for Csound. [NOTE:  This is rather poor, and at present uncontrolled.  Needs revision, and possibly more parameters].

INITIALIZATION

iatt -- time taken to reach full pressure

ifn - table of shape of vibrato, usually a sine table, created by a function

iminfreq - lowest frequency at which the instrument will play.  If  it is omitted it is taken to be the same as the initial kfreq.
 

PERFORMANCE

 
A note is played on a brass-like instrument, with the arguments as below.

kamp - Amplitude of note.

kfreq - Frequency of note played.

kvibf - frequency of vibrato in Hertz. Suggested range is 0 to 12

kvamp - amplitude of the vibrato
 

EXAMPLE:

    a1     wgbrass     31129.60, 440, 0.1, 6.137, 0.05, 1
