And the feedback knob.
The panel really does merit a couple deep dive videos online.

Truly! It’s works of art.

I really felt like I got more than I bargained for but it’s hard to put into words and features without actually sitting down at the instrument…

Hello! Here’s an idea for a patch that sounds like birds. It’s a complex feedback patch between the VCFQ, TWS, NCOM and DUSG. Clouds is also playing an important role in creating the different pitches of the bird sounds from the STEP OUT output of NCOM. Erbe-Verb is slowly coming in creating a virtual space for all the birds to “sing” into.

I have RS NTO in euro. It’s clean osc but it shines with wave multipliers for sines and triangles, and saw with vcfq and other filters. In comparison I only have Moog 901/921 clones they sound different (more full) but I always put them through c3p mixer which get some color.

NTO is really good with animation and where I love Serge modules. Some basic things like cv variable output can add a lot to the sound palette if you put a zadar complex envelope. I have a great bassline with it. Other modulation is also very usable (thanks for built in attenuators/verters.

Previously I have had Furthrrr Gen which was dirtier but also shines with timbre section. What I really want is a RS left part of Donks which consists 2 LPG and Buchla style timbre section. It gives some extra to NTO

I actually have the Donks module in 4u. TBH its got some flaws. The vactrols ring really long, like compared to the Easel I used to have. Also the Timbre section doesn’t have the range that my Easel had. I’ve tried a bunch to calibrate it to no avail, and frankly it sounds different than the Easel, it almost distorts like a guitar pedal. Which can be cool, but it’s not the same. Also I don’t think the circuit was adjusted for Serge voltages, it doesn’t fully open with the DUSG, but it actually does with euro stuff, especially with dynamic gate output on the 0-Ctrl. But having a cross fader between the two gate channels and the stereo mixer on the other side makes up for it. If I want a little Buchla flair it’s nice, otherwise I just run it like a four channel mixer.

Hi there - I just uploaded a short clip. The sound source is 2 x Vari Q’s

I’d go with the 2M2. Not only is that the value in Ken’s schematic, but in all of my research, he was pretty great about updating even the smallest of details. You could always experiment by trying each value. See which of them sounds/functions best… add a switch and use them both!

are the 258 j3rk/stroh pcbs?

I have no idea :grimacing: All I know is they sound great, whatever they are!

I’m 99% sure they are.

thanks man! I really want to build one of these.

They’re probably my favorite oscillator; indeed, all of my VCOs are J3RK/Stroh Modular, and half of them are based on the 258.

Can anyone reccomend any substitute ICs for the CA3080/3086’s in the 73-75 kit? Hoping to do rock an all tayda order but if it’s not possible I’ll try to snoop out something reasonable on ebay

I think Thonk carries the CA3080 and IIRC there’s the clone AS3080 from there (or via Erica Synths, in US I think synthcube carries CA3080). I think CA3046 (or AS3046) can be a replacement for CA3086.

has anyone hailed random*source lately? i’ve tried reaching out via contact form and instagram about repair, and no response.

my communication with patchpoint has been pretty abysmal as well. they’ve had one of my 4U modules in for repair for close to a year now with no communication as to when it will be repaired, why its taking so long, and as of last communication I even told them to just send it back to me, and I haven’t been able to get a response back. pretty disappointed because prior to this I’d had pretty good interactions with them…

really wish there was a reliable shop that was willing to carry the 4u Serge torch here in the states :frowning:

I haven’t gotten an answer to my inquiry from Patch Point either. It’s very disappointing, I’ve been there in person once and it was maybe the most pleasant experience I’ve had in a music store, and I’m so happy such a shop exists, so I really hope nothing too bad has happened and that everything will be sorted out.

I’ve messaged Random Source and haven’t gotten anything back. They also haven’t had things in stock for a long time, which is a bummer and has led me to sort of abandon/give up on the idea of getting some panels in the future.

R*S have developed a reputation for next to no communication despite fullfilling orders. Your best bet might be to reach out to Matthias Herrmann (Fonitronik) for help. He is quite responsive and helpful.

Then they should put him in charge of the emails. :rofl:
