Thanks for the suggestions everyone!

I don’t have a specific use-case in mind, but I’ve occasionally found it nice to be able to grab a knob and notch between values. It’s a nice alternative to smooth attenuation. Some digital modules do this inherently for settings. A utility that does this seems useful. I was thinking I just didn’t know what to look for, but it looks like this isn’t a named thing!

[joshhh]

A very big knob that could do this at programmed intervals (among other things) would be MI Frames.

As @Jonny mentioned, this sounds like Xaoc Drezno http://xaocdevices.com/main/drezno/

I am going off of the descriptions and videos so may be getting details wrong, but, as described, it converts analog signals to digital for manipulation and then back to the analog domain. One operation is bit crushing/down sampling (someone who knows better, correct term?), which I most often think of as That Sound That Bit Crushers Make, but which could just add easily apply to CV

So, you could feed it a sine, downshift it to 5-bit, and output it to get 32 discrete steps in roughly the shape of a sine.

Has anyone Drezno? I’m not even sure what to call it, in terms of category

[oscillateur]

Yeah, anything that does bitcrushing (and not sample rate reduction) will do that, but only with powers of 2.

My understanding was more like a module that has a knob (or CV in) to control the number of divisions, and then incoming CVs from the main input get quantized based on that number. So if you want 7 divisions you’ll have 7 different output values. If you choose 15, you’ll have 15.

That’s probably trivial to add for an existing module for which code can be written (hence my mention of Ornaments and Crime, especially the new dual alternative firmware for it) but I have no idea if that’s easy in the analog domain.

[xenus_dad]

Right would be limited to powers of 2 but would do it roughly out of the box. Most other options would involve some amount of config/programming, whether o_C, Salt maybe, or, Norns when Crow comes, or, well, Teletype which @grey, you said you’ve used for this. This kind of semi arbitrary thing seems right in Teletype’s wheelhouse.

[grey]

Yep. It absolutely will do that! I was mostly curious what alternatives were out there. @oscillateur is speaking to what I was trying to get at. The math is dead simple division in the digital realm, which is why I’m somehat suprised there isn’t a simple utility module for this, even if niche in use. I’d imagine there’s an analog equivalent.

[xenus_dad]

Time to prototype! 20

[_mark]

I am, but I’ve never used it like that. From the manual though:

So I guess you would patch across those bit outputs to the same bit inputs. I wonder if you could choose the number of steps easily though…

I have an SV-1 it good but it’s also limiting me. I feel I don’t use some features and the filter doesn’t do enough for me.

What should I get to replace it?

It’s got two oscillators, filter, mixer, adsr, vca, midi, lfo, sub Oscillator, Noise, and a sample and hold.

I use the main oscillator and mix wave forms. The second oscillator is useful.

I use the filter but it does have enough control. There is no cv for res.

I don’t use the midi or the noise and sub oscillators, nor the sample and hold. While these are useful I just get less mileage.

The adsr and vca are pretty barebones. They work, and I use them, I’d like more options.

Give me your thoughts and recommendations.

The A-118 in my 104hp Doepfer system is showing its limitations in terms of what I’m patching, and the A-149 isn’t my flavour of random. Does anyone have any thoughts on the ADDAC501 Complex Random? Seems pretty ideal, but for the price I want to be sure!

If you’re in the market for a filter (and everything else you mentioned!), I would take a look at this thread started the other day. Really helped me open up my patching with Sisters.

Mannequins Three Sisters

love. this. thread. so so inspiring, all! I’ve been living Six Sisters for a few months now and it’s been such an education. I’ve been using one as my main VCO, multing the signal into inputs on the other (FM’ing the filter 3Sis with a raw copy from the VCO 3Sis is deeply fun). stumbled on this the other day, exploring interactions between a voice 3Sis and a filter 3Sis with the help of Cold Mac: self-oscillate, keeping span just a tick CW of noon (12:05, not 12:10) voice Low -> filter Centr…

[Jonny]

Sounds like you’re looking for more of a west coast approach rather than the east coast approach the SV-1 takes.

Perhaps check out some Mannequins or Make Noise options?

[sandy]

@philmaguire What are you looking for in a random module?

[soggybag]

I have maths. The SV-1 sounds pretty good. I find the filter limiting it only has a single CV input. There is no cv for resonance.

The unit works well with its normalized connections but patching it into a different configuration is a bit of work.

Hey guys what’s ya thoughts on this rig to replace my korg prologue?

This rig a Norns and a grid then it would be fed into octatrack synced with my machinedrum and aux out to delay reverb

Soundcraft epm mixer

[electret]

Nice rig, have very similar. But this is not comparable to a korg prologue in any way so I can’t say…

[Bxentric]

I should mention My friend plays the chords for me after I’ve done the sound design on my keyboard. I’d like to not rely on someone playing for me and have more control. I figure I will use the Norns for my texture and this rig as the patterns for what I hope will be a deep techno listening experience

[electret]

Ah yes that make more sense then!

[Bxentric]

I’m rather nosey may I see a pic of your rig set up please?

[electret]

It’s changed a bit since but here’s a picture of the rack for my August live: https://www.instagram.com/p/BmbvzkmAyPr/?taken-by=electret_

I played this with a Digitakt. I’m preparing a new setup for a show this week, will share pictures after
