BTW Os built a Pulsar Synthesis mode into Disting after coming to one of Marcin & Curtis' concerts!
One of many things the Disting can do that I've just not had time to play with! Os might be about the only person who has tried everything the Disting can do for more than a few seconds 8-)

(It's nice to have weird capabilities in your back pocket though, for when you feel like you need.. something, but aren't sure what.)
I still haven't updated mine to be able to try it : /

Here's 28 seconds of my own recent work with nuPg
This rules. Definitely getting some Network Glass vibes. Makes me wish I knew more about SC, PD, and the like.

Can you tell us what's going on under the hood? How does nuPg differ from the classic Roads implementation?

That manual is a bit outdated, I've attached one for the version of the software I have here. While it shows what's in there, it doesn't really tell you how to use it ; )

Even though there's only a few months between them, Marcin had changed the way a lot of the modulation works, decoupling certain things, adding new ones.

While fundamentally the approach he's taken is similar to Curtis', there's plenty of new things in there, in terms of tools for shaping harmonic series, chebyshev waveshaping, different types of synthesis (e.g. fm synthesis with the pulsaret), and a lot more in terms of wider and more flexible modulation, sequencing and control linkage.

You can hear Marcin talk about the software in a talk he gave at ZKM here:

He's also contributed a chapter to a new ZKM publication considering Xenakis UPIC, Pg and nuPg here: https://www.zkm.de/en/system/files/fiel ... ay_zkm.pdf

If you'd like to get a copy (BTW it's Mac only at the moment, I think) there's some contact details here which he's previously advertised on twitter (very bottom of page): https://www.marcinpietruszewski.com/profile

Tell him I sent you ; )

To finish, here's a duet between nuPg and my modular setup:

Thanks for uploading the newer manual! I actually already have the software, it’s great.

Again, hardly a "deep dive", but I did patch up some (mostly) analog pulsar synthesis last night. For the euro-inclined:

Maths CH1 (linear cycle at audio rate) EOR > Maths CH4 Trig IN (non-cycling linear slope at faster audio rate)
Maths CH1 EOR > E350 Morphing Terrarium Sync IN
E350 XY OUT > VCA (CV by Maths CH4) > OUTPUT
Analog VCO sin OUT > E350 FM IN (optional)

Simple to set up, sounds the way it's "supposed to" when Maths 1 is slowest, Maths 4 is faster, E350 is fastest. Interesting undertones/subdivisions when Maths CH4 is allowed to get slower than CH1 (when window function exceeds duty cycle). Occasional glitches and squeaks, PS is definitely more predictable and smooth in digital implementations! Minute variations in trigger/sync thresholds make a big difference. But even leaving Maths entirely alone to drone, there's a crazy amount of timbral possibility just modulating the wavetable VCO's tuning, waveshape, and FM index.

Might make a video after fooling around with it some more if I make something worth showing off.

^ was wondering what an analog implementation might entail.
if you have the means - having a look at the waveform on a scope woulld be cool :-)
