This instrument is similar to the previous design: f51 generates
an exponential decaying envelope. By applying decreasing
durations for the note statements belonging to one additive
event, envelope f51 shapes the sinus waves non-synchronously. 

The frequency of the individual components is expressed by a
ratio to the fundamental. 

The bell-like timbre is obtained by 7 components (at 1, 2, 2.4,
3, 4.5, 5.33 and 6 times the fundamental frequency) with variable
durations. 

The second tone is obtained by only four additive components (1,
2, 2.5, 3.36). 

The durations are 3 sec for the first tone, and 4 sec for the
second tone. (Risset 1969: #410)
