Re: VCS-3 / Synthi-A trapezoid generator indicator light?

You just have to look, you can usually find something close on eBay if you have the right search. Dialight/Dialco made a lot of similar panel indicators for Moog and Buchla. Bulgin may have made the indicators for EMS. Many of the same lamps (and other things) were used in British made guitar amps a...

Here’s a similar red indicator, without bezel, with retaining clip:

Re: Phutney clone

hey Phutney Builders, how's your experience with NOS trannies and tropical fish caps compared to modern equivalents. is it worth the time and money? My subjective opinion is the same as above; yes to original transistors, but no significant improvement from tropical fish caps in the VCF. I tried se...

Re: Haible Son of Storm Tide in 4u

Do you have a panel design for it? I’ve been planning to make a SOST for about 10 years, but the feature set is so dense, it’s not the easiest circuit to lay out a nice panel for. I like the BBD Haible used in this design, think it’s comparable to SAD1024 or TCA350. This makes a huge difference in t...

Re: EMS Synthi Battery Pack

I wish there were more info/schematics on these early case side controllers. Looks as if it was a passive controller. I believe the “keyboard” was resistive, yes? And the “random voltage generator” was just a mechanical roulette wheel that would land on a random resistance value probably. AX wasn't ...

Re: PPG waves in eurorack wavetable oscillators?

I’ve also gone down this road with wavetable modules and I don’t think any of these modules really get the feel of what I consider a PPG wave/ wave computer etc type sound simply because they’re mostly all monophonic oscillators and to me the PPG sound is inherently polyphonic, chords and pads.

Re: sample/hold for minimoog?

Not what you’re asking.

But I bet it’s worth the extra effort, as it seems like a really well designed, full featured contr...

Re: Phutney clone

I regularly use a graphic eq to notch out 10db of noise at 500Hz, 630Hz, 800Hz, 1k Hz, 1k25 Hz, 1k6 Hz, and then scoop out another 15db of hum at 200hz using parametric eq on my board. After all this, I get a relatively quiet ground floor output. I’ve often been told the Synthi is a very Noisey inst...

Re: Synthi options

I wanted an authentic Synthi experience, but also felt it was too ridiculous spending $700 (or more) on a 16x16 or 20x20 ghielmetti (even though a 20x20 would make an awesome super-Synthi). For a one-off diy build, to me it seemed the best reasonably-priced compromise was an ‘off the shelf’ 15x15 (w...

Re: Grayscale Permutation: expanded Turing Machine + Voltages

The reference to the Rungler is interesting, now I want to try cross-patching two units together... It’s essentially the same circuit, just a matter of patching; although the Hordjik uses a 4021, with only the last 3 bits enabled, rather than 4015. I believe the rungler also uses a comparator in fr...

With a bit more trouble, you can send a pulse in to sync the internal clock. Most of or many of the Korg rang...
