Quad phased output LFO

Quad phased output LFO

2003-09-03 by klstay

Does anyone here know of a module/circuit for an LFO with 4 outputs 
with 3-way switches for ouputs 2-4 to shift them 0-15-30 degrees out 
of phase with the setting of the output "before" it? It would also be 
nice if there were a few "sets" of 4 outputs, each a different shape. 

OR, as I suspect may be the case, is that simply the stupidest or 
perhaps most impossible idea for a circuit you have ever heard?

It sounds like you want one of these, but with finer phase increments:

By the way, 0 degrees phase shift is useless unless this is under
dynamic control. Just use the previous output.

Re: Quad phased output LFO

I'd like to have one of these myself and I plan to build one if Paul 
or someone else doesn't first :)
My plan is to use a wave table and some counters.  You'd shift the 
phase by adding or subtracting from the counter.  The counter would 
point to an address in the wavetable.  The rate of the counter would 
control the frequency and the offset of the counter would control 
the phase.
This is very similar to my idea for a Fourier series generator and 
also very much like Paul's forthcoming Cloud Generator.
I'm planning on getting a stooge panel for this in the next run 
although I haven't built the circuit yet.

If the intent is LFO, it seems like it might be easier to do this with 
a microcontroller like a PIC or something.  You need to write some 
code but you gain flexibility and the electronics (basically the MCU 
and maybe a couple of serial DACs) will be less involved compared with 
a bunch of counters and associated logic.

And what you really want - have a few digits of 7 segment displays to 
show the selected phase separation and make it continuously variable 
in 1 degree steps.  Maybe have 8 outputs that are selectable - so you 
could choose 8 phases of one waveform or 2 sets (4 phases of two 
different waveforms) or 4 sets (2 phases of 4 waveforms) - something 
like that.

I've talked to Kevin and I believe this is what he's after. I'll be 
concentrating on getting this beast done once those 320R and 120R 
daughterboards are finished (real soon now).

That's a very interesting module!  But let's hope they call it a 
Voltage Controlled Function Generator as opposed to "Dr. Octopus."  
Ugh.

What is it with synths nowadays and wacky names?

Wacky names are fun!  My synth, for example, is known as the Engine 
of Chaos.  The imaginary quartet that employs me is known as Product 
Testing.  Come to think of it, most of our music could be 
titled "MTBF"-Mean Time Before Failure...or perhaps "No, Really..."

Now honestly, John, would you rather have a "voltage-controlled, quad-
output function generator" or a "Raging Multi-Moctopus"?  I don't 
think there's anything to discuss...

Chub...gee-that's sort of a wacky name, too!

Then there's products called stuff like "Akai MPC2000-EX-SE".  
Sheesh...... 

I don't name my dogs or kids like that, I'd never remember who the hell 
they were....

What I've found (from user feedback) is that many people like wacky 
names for modules, but few like wacky names for the controls. If a 
knob controls feedback, then most people prefer it to be called 
"feedback" and not "regurgitation".

I kind of like 'reguritation'..but will it fit properly on front panel ?

Er... Yes. 


Paul was pushin' it with "Wavewarper."   I'm here to keep things from 
getting too far out of hand.  :-)

Officially, that control name will be shortened to "hurl" to fit the
allotted space.

What would you call it then?

I just read Paul's description again (I can hardly wait for mine to be 
shipped) and I couldn't come up with much of a technical name for the 
MOTM-510.  "Voltage-Controlled Root-Unity-Power Modulator" maybe?  It's 
sort of a Ring Modulator with 3 inputs, so how about "Three Dimensional 
Modulator"?  I guess "Wavewarper" is as good as anything.  It's 
descriptive, short, and catchy.

And it's a wicked cool distortion device!

You'd use the standard abbreviation - REGURG

So then my suggestion of "Turbo-Ninja Signal Destrucktor" was nixed 
by your input?  <sigh>
