02_41_1
additional parameters: irise, idec, ifundr


This additive instrument shows individual an amplitude envelope
and frequency for each partial. Rise and decay times are
specified by the variables irise and idec. It is a simplification
of instrument 02_41_2 and based on physical analysis data of
trumpet tones.

The frequency of the partials is subject to small random
fluctuations. The range of these fluctuations is set to 6% of the
fundamental frequency for all partials. (Risset 1969: #200)
