It says it's a different design with no droop. My guess is that it's digital s/h under analog control.


which would be fine with me, these things would be better if they were digital IMO

Mildly off-topic, but releated...is this a new module as well:



...? I don't recall seeing it before...obviously I need to start paying more attention to Elby.


Entrainer

I can confirm the Toppobrillo Quantimator is perfect for pitch and is a
nice quantizer as well.

VCS looks nice, anyone know offhand what the default voltage swing is?


p3t0r

Really like the VCS, but with this size and price I think I'd take another maths. Still very cool though!


Monobass

I'm thinking about the DIY VCS and fitting multiple boards in a smaller but still generous space...

We do seem to be having similar ideas recently, Steve!

Where does it say this?
I'm looking at the site right now and here's the full description:
Quote:
The CGS734 is an analog control voltage shift register, three stages in length. It duplicates the functionality of the Serge ASR, but goes about it in a very different way. It is great for producing "arabesque-like" sequences, trills etc., when used with VCOs. Of course it's use is not limited to VCOs only.
Unlike ASRs produced using "bucket brigade" techniques, the CV outputs are constant from the beginning of the cycle to the end - there is no "charge period" in which a brief glide is heard.


I checked my frac ASR and it's CGS 34... perhaps Elby is using a different board? I'm not too up on my CGS so perhaps they make multiple ASRs.

I hope it works well, I love shift registers and use my Quantimator in this mode pretty exclusively. Like I said earlier, though, the CGS one I have is not really usable for pitch. I guess it's possible that it has a technical problem, but it seems to be functioning (despite being sloppy on pitch) as intended and there don't appear to be any trimpots to calibrate.

Bananlogue VCS and WVX are both listed as "preorder" at BCM...

Nice to see these two coming as Euro kits-Euro VCS is a pretty easy build with Ken's board set and I think Laurie will only improve on that if he redesigns the board (as he usually does).

If the ASR uses CA3140 opamps then it should have decent hold times.

Edit: Hope the VCS uses the level-shifted/inverted circuit from the 6" version of the board to get the AC Out rather than just putting it through a capacitor like the Bananlogue version

The CGS775 VCS actually uses Ken's own euro boards. It is part of the arrangement with Ken that this module uses that pcb and I am just supplying the front panel to complete the design. So the Panther CGS775 has the identical virtues of the CGS75 part.

Good job on these Laurie, looks like I'm going to have to start saving for another Elby order!

Cheers
Blair

EDIT: And the new shop design was a pleasant surprise... thumbs up

Did you build it yourself? Capacitor choice seems to be very important.


falafelbiels

So how deep will this VCS be then?






hyper
kits!

Am I the only one who interprets this as no droop?

Nope, it's a Metalbox build... Top notch quality.
I just google searched and found I'm not alone:

That one (and the Octave/Volts/Hertz) has been kicking around on Laurie's site as coming soon since about 2008. smile

That thread seems to offer a solution-it's variable offsets in the hold amplifiers. Maybe National LF411As would be a good solution to that?

Don't worry, this time it IS for real.

Yay!!! Great to see these two out in the wild at last! It's peanut butter jelly time!


KNYST

ASR kit! Yum! nanners

What are the measurements of the pcb?

7.3cm


KNYST

Depth of ASR?

Have a look at the schematics on Laurie's site-looks like he's modded the circuit quite a bit including offset trimmers on all the hold amplifiers and using a modern low on-resistance DG409 instead of the original's generic CD4052 CMOS switch. It should be better-performing than the CGS original (or the Metalbox).

These look great! May have to pop my kit cherry! oops


J

been looking at a few kits recently, and the VCS looks like the one to go for.
are these only available direct from elby?

cheers


Isaiah

Does anybody know the depth of the VCS at all?
Thanks!
