Hi list, A few unrelated questions: How do I get the highest frequency out of an A-110? When I send an envelope with sustain set to maximum to one or both CV inputs, I get approximately 1200 Hz (that's an estimate, I don't have a frequency counter, but I'd like it to go higher).

I believe you're indulging in a somewhat academic distinction here between diodes qua diodes and transistors configured as diodes. As Bruce Duncan, who designed Modcan's EMS-styled diode filter points out about: "The overall sound [of the EMS-style diode filter] is 303ish with ve

An original moog filter like the minimoog has 24 dB-lowpass-filters, a four time special tuned cascade of 6dB. the TB303 has a rebuild 3 cascade with 18 dB., which have lite other tunings and another saturation. The particular of the A-102 is the dependence between emphasis and c

2002-06-05 by buechlerjoe
You can make the sound disappear in either configuration. The test is whether you can hear TWO separate bands of audio passing thru the filter combination (high and low), or just ONE. If two bands, the filters are in parallel - a notch filter configuration; and if one band, they'

Yes, I should have added that while the TB-303 has the most widely- known diode filter, emulated on umpteen computers in ReBirth, in Oakley's superladder filter and TB-3031, and elsewhere, it's basically a -18 dB version of the Moog design, and that the Doepfer diode filter would

The TB-303 filter is in fact a diode filter, as described in this document: http://machines.hyperreal.org/manufacturers/Roland/TB- 303/info/roland.TB-303.secrets?0048 Therefore, it is your information which is wrong and not mine. All the best back, --Charles --- In Doepfer_a100@y

No argument there. However, that wasn't the question. The question was "what instrument is *usually* associated with a diode filter". The obvious answer is the TB-303, fetishized by technoheads worldwide. Most of those people haven't even heard of EMS. Therefore the word "bullshi

I think (and I'm not really sure because it's been a LONG time since I played with one), that the filters of the MS20 can only be configured in parallel... but I could be wrong. Also, with the arguement of Sallen-Key filters making poor bandpass filters, I'm left wondering. Anyon

Duff, 2 pole filtering has a 12dB per octave cutoff. Also, I think you'll find that when one uses a LPF and a HPF together, what is created is a notch filter (see the A121 documentation for a graphic explanation). Hope that helps a bit. Regards, Kevin

Duff, Sallen-Key filters are 2 pole filters. Also, using a true Sallen-Key filter for bandpass purposes isn't really advised, as the input resistor is a very low value, and changing the value also changes the overall behavior and characteristics of the filter. That said, Korg did
