PSIM-1 examples

PSIM-1 examples

2004-02-22 by Woody Wall

I've just posted some code and an audio file to the files section. The
code is called 'ramps.bas' and is *very* loosely based on the idea of
the Serge Universal Slope Generator. When a trigger is received at the
Start input, four one-shot descending ramps are generated. The basic
rate is set by the voltage at IN-1. The slope at OUT-2 is twice OUT-1,
OUT-3 is three times OUT-1, and OUT-4 is four time OUT-1. The ramps
can't be retriggered or the rates changed until OUT-1 reaches zero.
This way, it performs frequency division on the trigger based on the
voltage at IN-1.

The audio sample has two of the ramps controlling the frequency of a
Blacet VCO and the noise filter on a Dark Star Chaos. A Wiard Noise
Ring is providing the trigger to the PSIM-1. One of the NR random
outputs determines the ramp rate. The other NR out is controlling the
DSC noise clock. ARP 2600 is doing the random eighth-note bass line.
