hey funky
im designing my panel at the moment and didn't include step in
to be honest i missed that option completely
the only thing im adding is the disturb input as i have had some people tell me i it is very useful.
ill post some designs once i finalise |
I was about to omit the DISTURB thing...
I've used to see all these audio outputs as option...I went for this project with SOU 265 Sample and Hold section in mind...(correlation/cluster coltrol)
DISTURB involved active circuitry ? as for the STEP input ?

Quote: | Conceptual differences from Grant Richter’s design
The smooth tone output is a sawtooth instead of a square wave, making it suitable for S&H input.
I hooked the internal smooth S&H input to the smooth tone instead of the woggle tone. This keeps the smooth function independent. But it really doesn’t make much difference, because both of these are audio rate sawtooths.
The stepped S&H input is externally available, normalled to the woggle tone. This makes the stepped S&H useable as a stand-alone module.
The woggle range pot “input end” is fed from a buffered mix of two disturb inputs, A and B. The stepped output is normally connected to the B disturb input. This works like the WoggleBug, but the disturb pot allows a blend of the stepped and the A inputs. The stepped disturbance can be eliminated by turning the disturb pot fully counter-clockwise to the A input or by patching something else to the B input.
I have just two LEDs that indicate when each S&H is being triggered. |

"This makes the stepped S&H useable as a stand-alone module."
Nobody use stepped S&H as a stand alone module ?
is this really an option ?
i'm a little puzzled with this strange kind of module

i am far from understanding that schematic
it does seem useful to has step in to isolate a sampe and hold
i do want to build this module to fill the needs of that kinda of function in my modular
so im interested in this funky
btw i asked some peeps about the uses for the distrurb function and whether it is worth adding and this is what plord said.
"The disturb input is the only way to cause the Wogglebug to do something with input from an external keyboard or sequencer. The results aren't tonal or even predictable, necessarily, but if you leave it out you can clock the internal LFO, that's about it." _________________ problemchild

This sounds interesting, but I'd also love to see a project around the other sections of the 266 SOU, the Stored Random Voltage and/or Quantized Random Voltage. |

Richard's WB uses two LF398 Sample&Hold.....things i understand get fewer and fewer...maybe we could even delete this thread... |
