This additive bell is built with the OSCIL1 unit generator,
allowing individual durations to be controlled from within the
orchestra file.

The module OSCIL1i has been created specifically for this type of
instrument design. Csound enforces the use of a K-rate output
argument for this unit generator.

Substitution of OSCIL1 by OSCIL can not be done for the following
reason: the waveform oscillator is still 'on' after the end of
the envelope has been reached. This leads to a series of chaotic
sinus entries and clicks, depending on the duration ratios.

To avoid noise the envelope function f51 needs a minimum slope of
4096 to 1 before rescaling. (Vercoe 1993: morefiles/risset3.orc)
