01_12_1
additional parameters: if1, if2, iperc, ifqr


This instrument permits to add a noise band to a pitched sound
with variable envelope and waveform. The basic instrument is
modified to include a RANDI unit generator. The variable iperc is
a percentage of iamp and varies from 1% to 300%. The effect of
roughness/noise introduced by RANDI is clearly perceived in this
design, in contrast to instrument 01_11_1, where the LFO had
complicated the soundscape.
