SStart, SLoop, SRetrig. explained?
2010-04-27 by Atom Smasher
going through the archives, it looks like there's a lot of head-scratching
over SStart, SLoop, and SRetrig.
hundreds of pages of doco on these synths, and AFAICT this is the most
comprehensive description of these features to date. after a bit of
methodical experimentation...
SStart:
*note-on
delays the sample start point. with some of the longer samples (eg: drum
hits, organs, pianos) this is almost like adding new ROMs full of new
waves (have you ever wanted the sustain section of a sample, but hated the
attack? problem solved!). this seems to have no effect on single-cycle
waves (eg; basic square, sine, saw).
SLoop:
this seems to adjust the loop-start point. with some of the square waves,
or similar, it can accomplish PWM; on other waveforms it sounds kind of
like hard-sync. on some samples (most obviously, those that don't loop)
this has no effect; on other samples it sounds like crap and just makes
clicking noises.
SRetrig:
re-triggers a sample as the falling edge of a trigger source reaches 0.
does nothing after a [non-looping] sample finishes and ends. affected by
SStart (which, unfortunately, only takes effect during note-on). an
obvious application for this is rhythmic effects.
all of these parameters seem to respond only to positive values, although
SRetrig doesn't care about anything except the transition from +1 to 0.

"They do not bear arms, and do not know them, for
I showed them a sword, they took it by the edge
and cut themselves out of ignorance. They have
no iron. Their spears are made of cane...
They would make fine servants...
With fifty men we could subjugate them all and
make them do whatever we want."
