[RE: [Re: UNFAIR LFO voltage?]]

[INDRID COLD]

besides the good advice i have gotten on LFO voltages, i have found myself
unintentionally more knowledgable about guitars than i was previously. well i
guess you learn something everyday. this knowledge could possibly come in
handy some day. as far as LFO options goes; ultimately the chosen option is
very much a function of panel space. so far i have rate, symetry, CV-in level,
and i may add an uncomitted CV VCA with level control. thats four if i don't
have to use 2 knobs for optimal symetry control. one of my cheesy little
mini-box modules actually has 12 knobs on it, along with 6 jacks, 6 LEDs, and
a push button. i guess if i wanted to go crazy i might get away with option 3.
we shall see. mike.
BTW- i kicked the 8038s ass! lots a range now ;-)


I agree - and yet sometimes I don't. 
Sometimes I find myself asking how to *remove* another knob rather
than adding one. I used to think that as many knobs as possible 
is the one and only way - until I stood face to face with one of these
Jellinghaus (sp?) DX-7-Programmers one day.

Let me take up that example of the unipolar / bipolar LFO:

(1) The cheap solution:
"What - how could anybody want anything else than bipolar ?
You're the first one to ask such a strange thing"

(2) The cheap solution, vol. 2:
"If you want to have an optional level shift, buy our Voltage
Processor module, and mix in your desired offset voltage."

(3) The "I thought of everything" solution:
One knob for output level, one knob for DC offset, external
CV input for amplitude control, external CV input for DC
offset control, two more knobs for sensitivity of these CV
inputs, center Zero pots for increasing or decreasing
the parameter ...

(4) The "guitar amp" solution:
One knob for LFO output level. Pull-Pot switch to add
a carefully chosen DC offset to emulate a certain
fashionable effect derived from a natuaral instrument's
behaviour.

There may be more, but you get the point. My own
"roots" are surely in option (3), but I start to see the
advantages of option (4) more and more.
