Classic Moog ladder filter anyone?

Hi
Has anyone successfully modelled the classic Moog filter in Flowstone or Synthmaker? Is it possible?
The analogue circuitry used a transistor "ladder" which meant that the inherent non-linearity gave rise to a very characterful sound.
It's my opinion that it's the filter that most distinctly differentiates analogue from digital synths and very secondary to this would be other factors like saturation and noise, easily produced in digital.
It would be very interesting for me to compare any "regular" Flowstone filter with such an emulation.

Cheers

Here are two implementations. ;)
I think what made the legendary Moog sound so unique was actually the 4th order 24dB/octave falloff, compared to other synths which featured 12dB/octave filters. The nonlinearities were a goodie to control self oscillation, but I think it was the filter steepness that made the difference. At least for me anyway.

Hi Martin
That's superb, so many thanks!
It seems I only have to ask and you give.
SO... can you design me a filter with 6 outputs? The outputs must be the winning lottery numbers for next week...

Hey Spogg, I gave it a second thought and came up with this lottery number device. Here is my proposal: Go buy a lottery ticket. Fill in the numbers obtained from the device. As is often the case with such generators, you have to supply proper seeds at the six inputs - that's where we need your Volcan skills. Submit the ticket. If we win we split. (Remember that it was me who provided the generator after all.) If not, try next week.

Deal? :mrgreen: :roll: :lol:

Deal!

I love it :lol:

There's not quite as much MartinMagic inside the module as I would have expected but at least I think I can see how it works, unlike every other filter you've ever made!

I shall treasure this forever.

Cheers
