Muff's Modules & More

Just gauging interest in either a single width dual, or double width quad Low Pass Gate module in MU - no resonant feedback.

+1 for single width

Why no feedback?

Nice concept for a module. I suggest single module dual lpg's.

Just thinking (a rarity!) Do I recall someone else having a MU LPG? Can't recall who.

Could definitely be interesting!

I'd be down for the dual single width then realize i'd want another... so i'll cast my vote for the quad LPG It's motherfucking bacon yo

I'm down for a quad for sure it would be a welcome addition to 5U.

There's the Megaohm LPG which is very full-featured (resonance, dual CV inputs, switchable filter responses), and I believe roman_f was also considering making a clone of the Buchla 292 as part of his Sputnik line.

I already have two Megaohm CdS's, so I wouldn't buy more LPG's, but I think a dual LPG in a single width module may be very attractive. A quad may be too much for some people, especially if they already have a few VCAs.

I have one of the QLPG's from Cyndustries but would consider the resonant LPG to be useful.

I would regard the dual, 1U to be more popular for many reasons. I rarely use all four channels of the Quad LPG in a single patch.

Ok, I'm home and more relaxed... (rough day in jury duty). Enjoying a beer and some Masonna CDs. Guinness ftw!

So, as I mentioned, MegaOhm does the CdS VCF/A, which is a fantastic module (I have two!) - it is resonant, with other goodies like a CV input attenuator & CV input VCA.

But, I think some sort of more compact module would also be great, for when those other features aren't needed. Personally, I really enjoy the CdS both with and without resonance. For me, feeding a LPG a pulse is so much more fulfilling than sending the pulse to an EG and then a VCA. Perhaps I'm impatient, perhaps after many years I still feel uncomfortable with ADSRs, I dunno. But, no matter: I really like the result.

Not sure exactly when, but Cynthia used to make some Quad LPGs in MU format. I didn't find out about them until they'd been discontinued. I know a year ago she mentioned to me the possibility of doing a few more, but I'm not sure if this will ever come to pass, as she is definitely changing her business model & manufacturing techniques. But, of course, I can't speak for her!

Here is a pic she sent me; personally, I really love the layout. (I have other pics too.)

I have heard, however, that the CV on this is a bit wonky, or at least that it wants 10V CV inputs to fully open the gates.

While I have 10(!) PCBs for the Craig Lee LPG (with VC response) PCBs, and plan to make 4-8 in MU format, I would love at least one quad LPG - I think it would pair particularly nicely with my Moon Trigger Sequencer. But, I could see a dual 1MU being more popular.

I know this has come up before but for whatever reasons I still don't understand how a lowpass gate works.

wsy

The MegaOhm Delta filter (three pole, controllable resonance) has the feedback
path to raise (or lower!) the cutoff frequency based on the output. So, you can
do an LPG with a few knob twists.

I think the MegaOhm Delta has replaced the Steiner as my #2-to-buy MU format
filter... maybe. I still think people should start with a state variable filter, but for the
second filter... hmmm... the Delta is a rising star to me.

There are several LPGs around but only one HPG that i know of, the COTK C906B:

I've never heard one and wonder what it is like! hyper

I have two 292e clones on order from Roman/Sputnik. Each has a single channel, and I am hoping for full Buchla performace. I also have a 200e so will post a comparison when they arrive. Right now Sputnik has five pcbs in various stages being built and MegaOhm are out; so Doug I think a larger production run which is more compact and readily available would be welcome.

Interesting hmmm.....

As this has come up I will be making a small batch of This Triple LPG in MU Very soon

wyrtti · Posted: Fri Apr 06, 2012 12:59 pm Post subject:

And a wonderful triplet it is. The third on mine is a bit slower and the first two are twins. Awesome module!
And those smaller MOTM knobs are so cute...

another vote for the quad double.

i definitely need some vactrols in my system.

fwiw, i really like that cyndustries design.

I'd be very interested in a 1MU dual LPG module.

But I would still be happy if the project comes alive as a 2MU quad.

Double, triple, or quad?

To those who want dual-width quad LPGs: would you purchase two single-width dual LPGs or does it have to be a quad?
