Serge thread

It’s not that different than using a unquantified voltage source on a 1v/oct system; you just have to scale your voltage to get the pitches you want. I’ve been using an SQ-1 in linear voltage mode with my 73-75 system when I want to get melodies and it works well. I just attenuate the incoming voltage until the maximum voltage (I set the SQ-1 to 5v) equals two octaves and then I tune the sequencer by ear.

Yup! pretty much what @hinterlands says. To scale the voltage input, here’s a handy video from Doug Lynner. You’ll also do this if you want to track oscillators together from a single voltage source.

Ah cool thanks for that!

For any 73-76 Homebuilt owners out there. I’m close to finished stuffing the first board, and I suddenly started second guessing my choice of pots. I’ve gone for the specd non-threaded alps pots, but I think that the pcb itself feels a bit springy, so now my worry is if there is any “push in” or spongy feeling to the pots once mounted?

Tldr: How does the specd non-threaded pots feel? Do they feel good, or is it worth it to go pay the extra for threaded alps?

I have the voice and control panels pre-built from Jon. I also have the Homebuilt. The ones from Jon have the non-threaded plastic shaft pots. The Homebuilt has threaded metal shaft pots. The threaded shaft pots certainly feel less Wiggley. The threaded pots panels have an overall more solid feel. The others aren’t bad, but if you have a choice, go threaded

That was what I expected, but also feared, to hear. I already bought the threadless jacks, so I’ll propably just carry through with the build as planned. Buying alphas home from Thonk has become quite a bit more expensive after brexit, and I was planning on this being a “cheap” entry into Serge.

Let’s see. Maybe I can figure a way to add a couple of more spacers between the board and the panel instead.

As I said, I’m completely happy with the feel of the panels with the thread less pots. It’s a nice box.

“I seem to remember reading that Serge’s response was essentially “Sure, whatever” – he didn’t care much about that stuff at the time.”

It was quite the opposite actually. Serge was tired of people stealing his designs and making money from them without so much as asking him. It was only because I was willing to pay GOOD royalties per board, and not “rules lawyer” him out of what he was due that we could proceed. Fair is fair. It is Serge’s IP after all.

Thanks for clearing that up Ken, and my apologies for misinformation above. I have edited my post so as not to mislead anyone who comes to this thread in the future.

I saw your question while browsing through this thread. Yes, I have some info about Charlemagne’s drone machine. A few years ago I restored it for a concert of his.

It consists of two identical panels, each with a Buchla 295 octave filter bank, some mixers and four oscillators designed by Serge Tcherepnin. Every oscillator outputs a sine-like waveform, a triangle, a pulse and a sawtooth. There’s a pot for the pulse-width, a 10-turn frequency pot and a 4 position switch to set the scale of the frequency pot. No voltage control.

A photo of the front panel:


Bottom right: the controls of two of the four oscillators
Above that: mixers to mix the four waveforms of each oscillator
The 16 mini-jacks bottom center: the oscillator outputs for the 4 oscillators of this panel
Bottom left: mixers
Top left: the 295 filter bank

The description of the 4 Buchla band pass filters and the 16 ultra-stable oscillators does not completely fit the panels I restored, so maybe he also had another Serge-Buchla drone machine.

sort of embarrassing question but I’m hoping someone can identify the Serge paper face in the image below? I think I found in on the net somewhere ages ago and then used it in a presentation but now the presentation has been made into a video and I need to attribute a source to the image. Strangely I can’t find it anywhere even with a reverse google image search.

Any help much appreciated if you recognise it!

It looks close but not exact to a 1974 system Serge Modular Music Systems
Have you asked on the Serge or 4U FB groups? Serge himself is in former and Ken Stone in latter.

Thank you I’ll inquire there!

Was originally the 3.5mm version, but he’s since switched to SERGE :slight_smile:

For Bandcamp Friday, could I get some recommendations on serge exclusive records doing that nonlinear, feedback thing? I like what I hear around the forums, but don’t know of any artists to check out…

Thanks in advance.

You can hear an obvious live recording of this from six minutes into the B-side of my first record. Though there’s Serge recordings on all my other albums too.

I’ve made an album recently completely made with Serge Feedback Systems. It was a life changing experience.
