133 Ohm sounds a bit much. :hmm:

I think it doesn't work quite the same way as resistors. If you put one of these beads on your DMM it reads 0.2R. I think it's frequency dependent or something. There's another thread here (or maybe on electro-music.com, it's been a while, I can't remember) where there was some debate along these lines, and one of our esteemed designers (maybe Jurgen Haible or Ian Fritz?) posted a technical description of what they actually do, and why subbing resistors isn't always the right thing to do. And also why resistors are sometimes the best choice.

Good to know. I think I have some 133 Ohm ferrite beads hidden somewhere because I thought I bought the wrong ones.

I think the ones I use are 135ohm, I have lower ones, around 85ohm if you want the part number for those?

Holy shit that looks amazing :hail: simply amazing work!

I was going to pm you for wiring advice on how to get around the switching jacks while using bananas; but i see you are using 1/4"

Thanks all!

You could ask Ralf at random*source - he certainly does a lot of banana stuff. But I don't think there's much if any issues - JH had the CV inputs normalled to ground via the switching lug, but I don't think that's a requirement - it'll probably work just fine without those. The euro adaptor board skips these. The only normalization I used via a switching lug is from the mix out to the VCA input, and you could certainly skip that.

BTW, calibrating the scaling of this thing is a major chore. I just spent like an hour trying to get things close, and thought I was good, until I tried all 3 VCOs together - I can get maybe 3 octaves fairly acceptable, but past that - well, I need to try again. Tomorrow.

yan - i did a 4u of the lvco - no normalization/adaptation is required. simply wire bananas to the "tip" on the header.

I have to say, the re-release of Jürgen Haible PCBs by Random*Source has increased the size of my setup significantly... Thank you, Random*Source! Too bad that I can't thank Mr. Haible for his incredible work...

I love your front panel designs! Really nice work.

After three nights of wiring its done :banana: I wish I could take credit for the front panel, but Charlie, The Bad Producer made it and did simply an amazing job :tu:

I have no idea how sduck got all his connectors to sit beside each other. Mine were so tight I could only get two or three of them together before the interference was too tight for them to fit. That is why you will see a section of header missing and wires just soldered to the board :oops:

Just one more small vcf and this box will be complete :bananaguitar:

I assume no one has tried running the Tau Pipe phaser on 12v?

Kinda. It's functionally completed but not cased yet. Just nailed to a piece of MDF.

I took it to Synth DIY UK in Cambridge a couple of weeks ago. Michael Zacherl took this video. Lots of ambient background noise though ...

re: Vocoder: Does anybody know if there's going to be another run? Missed the first run, and would really love to build one.... :hyper:

Did you solve the freeze/accumulate switch issue?

me also I have an original board in my backlog along with some other original haible boards, will get to them eventually .
would be good to see an example of how that one is wired.
It probably wont happen today but if it does it definitely wont go smoothly.

No, I still need to look at that. It's the accumulate that doesn't seem to work as expected :hmm:

Sounds great, what's being used to control the pitch?

The excitation signal was a Streichfett string synth controlled by a CME xkey 37 keyboard. The source signal was BBC Radio 4 supplied from an IPad. :hihi:
