Re: Smooth Stepped Cycle Jacks?

2004-11-02 by Bob Hearn

It does exactly the same thing. CYCLE is +10v when high, and -10v when
low. When the output goes above about 4v, CYCLE goes low, and when the
output goes below about -1v, it goes high. (Those number seem odd - I
wonder if I have some strange power issues? I don't remember noticing
that before...) To get the stepped section to oscillate this way,
though, you also have to supply a stream of pulses to SAMPLE.

A month or so ago I spent some time really grokking the SSG. I think I
was able to completely satisfy myself on every point about its
behavior, even answering some unresolved questions from SMOG. The
module really does make sense; all of its apparent strangeness can be
explained.

One interesting thing is that the stepped section is just like the
smooth section, except that (1) the slew rate range (knob + cv) is much
higher than the smooth section, and (2) SAMPLE rising edges are turned
into short, fixed-length pulses, which when inverted become the
effective HOLD input. I.e., it doesn't actually step; it just slews
very quickly for some short, fixed period when you pulse SAMPLE.
