I noticed dizzeesatchel had both in a different thread. I didn't want to hijack that one, but I'm really curious, does rbss work through the quantizer?
Thanks!

Anything works with a quantizer. The RBSS sends semi-random voltages, which can be quantized just the same as any other signals. And that’s in fact one of the awesome things about the Turing Machine system in combination with a quantizer. It generates a sequence of notes in a scale which can be locked/repeated and then slowly (or quickly) changed and locked again. Even under CV control. Pair that setup with another random generator and a SOLINA and you’ve got infinite melodies and backing chords which are never out of tune (if set up correctly).

I actually just found an example from years ago on my YouTube channel, when I was still into Eurorack. The MPC sequences drums and the long, somewhat “bassy” notes. The fast, higher pitched melodies, coming in at 0:36, are a Eurorack VCO, played by a Turing Machine through a quantizer. It was a uScale, which let you choose in real time which notes were in the scale.

It seems to work fine - i noticed perhaps a minor bit of 'wobble' now and then, as if the Q was struggling to lock in the note - but that might just be a result of my chaotic patching, or a side effect of my limited experience with/understanding of the turing machine concept. edit: just rewatching the below & realised the wobble might be from modulating the wavetable perhaps, rather than anything to do with the RBSS or Quant. Should probably test with a simpler signal to be sure.
Here's a quick video demonstrating an early attempt with the RBSS where i sent the CV through the quantizer:

Thanks to both of you for your answers, cool patches!

In advance of the next round of RBSS modules going on sale, I made a clearer video, inspired by this:
I wanted to start with a fixed sequence and use the RBSS to introduce variations. In the above video they talk about using a voltage adder but I'm not sure if this function exists in the AE world yet(?), so I settled on using the B channel of the MIXER module to combine a preset CV sequence (from Korg SQ-1) and the CV from RBSS (if there's a better way of doing this let me know!). I found it useful to pass the CV through the 2ATT/CV to help control the range of variation, and also, by turning the 2ATT/CV down to zero, you can return to the original sequence! After combining the CV signals, I'm passing it through the QUANTIZER just to demonstrate that this works and you can move between scales and use offset as normal. The RBSS is being clocked using the same gate pulse from the SQ-1 which is opening the VCA.
In the second half I switched to using the internal clock at a high rate to generate a sort of chiptune/fast arpeggio sound, which is something I stumbled across while making this

Gotta get a pair of rbss!

So, the answer to the subject turns out to be 'mostly'. Depending upon any modules between the rbss and the quantizer, there may be some glitchiness. I've just added a post to the Wonkystuff website describing the issue and its simple fix. I realise that soldering is not for everyone, but I hope that people can find some helpful local to perform the modification as shipping the module back and forth for the update will be prohibitively expensive I'm afraid. wonkystuff.net/rbss-quantizer-issue/

Hey thanks for the update! I haven't been especially troubled by my experience so far but at some point i'll probably get around to this. Never soldered before, but if worst comes to the worst i'll rope my ex-TV engineer dad in to help (one day in the future when it's safe to visit family again...)

If you have the capacitor and a soldering iron it's quite literally a 5 minute job - a TV engineer could probably do it with their eyes closed

SWEET! I was wondering if a fix had come. Might have to head to Raido Shack this afternoon.

just saw the note in another thread about 2CVTOOL also rectifying this glitch - maybe something i'll consider instead as a less permanent fix - after all, maybe there'll be times when the added chaos it introduces might be welcome??

Does it have to be a 103 capacitor? I don't know anything about electronics, but I do have an old soldering iron.

Does it have to be a 103 capacitor? I don't know anything about electronics, but I do have an old soldering iron. Yes, it needs to be that value – 10nF. Other values might do something, but you may find that you introduce portamento/glide with larger values — and smaller values will still let the noise through.

Have the new ones had this fix? I'm just messing with mine (thanks for speedy delivery!) and I'm getting ripple through the quantizer.

Mines 140 I think, though it's definitely wobbly.

Does the led flash uniformly on the quantiser or sort of flicker haphazardly when you get a bum note?

Yes, all rbss past serial #130 have already been modified — the extra capacitor is actually a surface mount one added near the output pin header. You should see a short wire and the (tiny) new capacitor. Sorry that you’re having problems I think that there will always be some edge cases where the output CV is on the margin of quantiser steps, and so will jitter a bit, but to be honest that doesn’t happen very often in my experience. If you would like me to send a replacement, I can do so (I’d ask for #140 back so that I can investigate!) — PM me

Thanks for that - I'll do some more playing today and see how often/where I get the jitter. I think from my first play it's only at the extreme high end so perhaps that's to be expected for the module?

So more fiddling and identified the issue - it's my end; when running via powerbank & myvolts I get a jitter in the uppermost CV. It's fine running from the mains adapter though, so the power is the issue rather than the module.
Appreciate the support offer though and love the modules - for anyone on the fence I highly recommend this and the vca!
