Title: [nonpedal] Minimoog VCF
Post by: alanp on May 19, 2014, 11:12:27 PM
I know, this is really not a pedal, but I think it's dead cool :D

Mmmm mmm mmmmmm. I think I posted about this in the synth-diy thread, but this is the finished article!

did you get the panel screen printed?

Front Panel Express. The art is engraved/cut into a black anodized panel. Very, very well done, but it better be. Why? You've heard the expression to charge like a wounded bull... think more bull you just kicked in the nads.

That looks sweet. What does it do exactly though?  ;D

That is quite cool, I'm wondering what it does? LFO? CMOS synth?

That looks crazy sweet!  Must make some really nice space ship sounds.

It's a copy of the Minimoog synthesizer's low pass voltage controlled filter.

And yes, it makes some sweet sounds :)

that is so great......man, super inspiring.

Do you have keys yet? If so, what?

No keys yet ;_; been using a FreqCentral Waverider LFO and System X Envelope to control it.

Got a sequencer in the pipeline, but hit a snag with the faceplate.

Very nice!

Was matching the transistors a bugger?

The Moog Ladder filter is one of the nicest sounding filters IMO.

The filter in my prodigy is just lovely.

I have built a few of these and in the first 3 I matched the transistors (BC550 I think), and in the now defumct EFM filter I just stuck em in. All worked fine.

Bit of a dredge, but would anyone be interested if I did ten sets of boards for this?

New revision, uses less HP (and panel space), all boardmounted, two stacked boards (think Brazen Bull, but less impressive.)

Count me in.  I still need to buy that sequencer board off of you.

Alan, I am in if you do end up doing a run. Maybe there wasn't enough interest?

Did a follow up to this -- no spare panels left, but I still have PCB sets for it. Rullywow can laser panels for it :)
