DESCRIPTION

Audio output is a tone related to the striking of a cow bell or similar. The method is a physical model developed from Perry Cook, but re-coded for Csound.

INITIALIZATION

ihrd -- the hardness of the stick used in the strike. A range of 0 to 1 is used. 0.5 is a suitable value.

ipos -- where the block is hit, in the range 0 to 1.

imp - a table of the strike impulses. The file "marmstk1.wav" is a suitable function from measurements, and can be loaded with a GEN1 table.

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

PERFORMANCE

A note is played on a cowbell-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
