designs.  And one of the modules that Doepfer came out with that people said

didn't exactly invent himself.  The ridiculousness of it all.

Sure you can.  Just use the same components which can be bought by anybody.

Hi Kenneth and all,

>In addition, all this finger pointing at Doepfer as theives coming from

You are right in the strictest sense. But there is a big difference, to
me at least, of what myself and Paul are doing. Korg no longer make the
MS-20, it hasn't been made for twenty years or so. The TB303 hasn't been
made for a similar time. By releasing the MOTM-420 and the TB3030, we
are not doing any harm to sales of new TB303s and MS20s. Furthermore,
both of us have added to the value of the designs we have liberated. I
believe Doepfer has not. He has taken the MultiLadder, already a modular
panel, and bunged it on one of his panels.

I have the circuits for the Serge Wavemultiplier. Probably the only
module that I would like to copy from his range. But it will not be a
Oakley module.

There is a question of decency here. Deopfer is small business, I am
too. I thought there was decency among the little guys. Perhaps not. But
as I have said on the DIY list I am not angry. Far from it. And in some
ways I am flattered.

And true, I am not the only person to have discovered multi-tapped
filters. The 3320 based Oberheim Expander was the inspiration for the
MultiLadder. However, for patent reasons probably, this was never done
on any Moog ladder before to my good knowledge. The ARP Qaudra's phaser
was probably the closest any one got. My work with Moog ladders goes
back a mere five years, and SuperLadder was born from that. Discussions
about my findings with the subtraction of rung one and rung four of the
ladder on the synth DIY list with Magnus Danielson and Grant Richter led
me to the Oberheim Expander. From then the MultiLadder was born. So yes,
it was the fruits of many people, but I don't hide that. Its all on
public view and I have thanked people for this. Doepfer does not.

Polyfusion ? What Polyfusion ??

Just to clarify: My SSM-style VCF for MOTM is not just a clone of the
SSM chip, or of any existing circuit that uses the SSM2040 chip. While
it's capable to emulate the standard 2040 application (as in Prophet 5
etc.), you cannot emulate some of my filter's features with any circuit
built around an original SSM2040. (You could, if you had access to
an internal node of the chip.)
Believe it or not, I spent weeks of Spice simulation and testing to
make that circuit what it is. A good deal of that was to explore
things that belong to "forbidden conditions" according to the SSM
publications (and which therefore was avoided by all manufacturers
that used the chip back then).

Doepfer's module was similar to the Polyfusion Quadrature LFO.  But when 
Doepfer anounced it, everybody said they stole the idea from you.  I was just 
pointing out the fact that a similar module was around way back on the 
Polyfusion.

Quadrature LFO ?
I never heard of anybody talking about this.
Normally people who accuse him of stealing refer to other things.
Personally I avoid the word stealing, and I'm generally sick of
reiterating all that, so don't ask me "what exactly is it about"
- it's all in the archives of synth-diy. He does what he does, it's
certainly
not illegal, but personally I despise him and I see the reasons for others
to have the same feelings.
Strange how all that is altered and transformed by word of mouth
(and of email). Who came up with that QLFO Polyfusion thing ?
