Even though multiple outputs would be ideal, the single output works well for me through any filter (Ripples, Wasp, Moog).

In my experience, the retrigger option is key. If you're holding a chord with your right hand and playing a bass line on the left, you don't want to retrigger the filter envelope (and re-articulate that higher sustained chord) with every bass note.

Conversely, a lead melody over a sustained chord works best if the filter envelope is retriggered with every lead note, and the fact that the chord goes through the same filter opening and closing again doesn't matter that much, as it's in a lower register.

By setting the retrigger behavior appropriately, I don't really miss having a separate filter envelope per voice, thanks in part to the individual VCA envelopes. Also, sending that mono output through a good stereo reverb makes it super lush and wide.

It's a full ADSR envelope. You can set the Decay and Sustain stages by holding the Function button and turning the Attack and Release knobs. That's crucial for polyphonic playing, in my opinion, as it allows a new note to draw attention to itself, then fade into the rest of the chord as it goes into its sustain stage.

Oh thanks for letting me know about setting sustain/decay!

Okay, it's time for the first official firmware update, v1.1 is out, see http://supercriticalsynthesizers.com/de ... scillator/ (end of page)!

The update fixes two things:
1. Since the control for the amplitude in the virtual VCA's is digital, there is some inherent noise when the amplitude is changing, and this was audible on medium attack and release. However, the level of the noise was _much_ higher than strictly necessary, and the new firmware takes advantage of that to reduce the noise to essentially inaudible.
2. There was a bug where the maximum frequency was limited to about 600Hz, if the module was set to Pulse waveform, five voices, stack of three. The limit has been lifted to 2.5kHz.

Hopefully you'll have no problem updating!

Nuts & bolts day! We’re listening 80’s pop today. This second batch is going to be bubbly. The playlist’s name is titled ”80’s - Miami Cocaine”. Last batch was made to the beats of Aavikko.

Härifrån tvättas! This is a teaser of a new prototype we're working on. All the filtering and distortion is from this new circuit. No external modules used apart from the Demon Core Osc. Its's set on basic 2 saw mode with 8 note polyphony.

So far we've described the machine to be/have "SEM-my", "liquid", "crunchy", "distortion for days", "capable to be very unstable", "formant-y" and of course basic "fat". Depending on how you adjust it.

It's analog.

Yeah, that sounds spectacular. Very versatile, from clean to dirty, even a bit of WASP-y warble around 4:40. :love:

This is dirty and pornographic! After listening to this demo, I had to take a shower to wash off all the sleaze... and that's exactly why I want this.

Hi y'all!

Quick update! We're planning to add more stuff in the DCO. The new firmware 1.2 is already in my modules for testing but I thought I'd let you know about this at this stage:

- Since there's a hidden FM LFO behind the modwheel and FN + FM, why there shouldn't be a portamento? That would be behind VOICES + FM. Let's make it poly portamento as well! Goes from quick to 10 seconds.

- There's also a mode for the four CVs in the expander to also act as polyphonic gates. The gates are triggered from a quick change in pitch CV. The gate/sustain length is set by FN + expander FM AMOUNT. So in gated mode you get four polyphonic pitch CVs with triggered VCA ADSR-envelopes.

Of course there's some bug squashing, but I'm totally stoked of these two new features. The CV gating sounds very cool when using with uO_C's four channels of turing machine. The poly portamento is all THX intro stuff atleast on my hands.

We'll let you know when it's ready.

I'm in the process of making two series of videos which we're releasing on our instagram account @supercriticalsynthesizers. They can be found also on our facebook site. One is a video tutorial series about all the handy features and the other is about some applications you could use the DCO on.

Fantastic. I don't recall experiencing any bugs since he last firmware update, but the new features are very welcome!

Yay, those are two features from my "imagine if they managed that" list!

After enjoying the hidden LFO, I'd been thinking about portamento as the only thing missing from the excellent midi implementation.

And for CV control, I always wondered if there would be a way to "generate" individual gates by listening to CV jumps. Kind of like the way Rings does it if nothing is plugged into Strum or In... Of course, Rings only requires a trigger, not a gate off event, so I didn't know how you could derive that. But setting the length globally with one of the button/knob combos is a good solution!

¡Hola!

Firmware 1.2 is out now!

Check it out and play them sweet robot noises to your module from [url=http://supercriticalsynthesizers. ... ator/]here. Be sure to read the instructions.

Please let us know what do you think of it!

We’re doing a workshop at Schneidersladen on 7th November 19:30 local time. Pop by and say hi if you’re in Berlin. A video version workshop should end up in the internets at some point. We’ll let you know.

ordered my demon core and expander today :) pairing with the stereo dipole for now. when can we learn more about the filter you're creating? thank you!

Very tempting oscillator...technically.

It's really a pity that it has a pentagram on its faceplate and a "demon core" because that way it s a no-go for me personally. And I'm generally very interested in polyphonic stuff. Recently, quite a few modules seem to be predetermind to be dark or even evil. i, personally, do not think that it is funny or stylish or meant that way in some cases. I understand that there are people who make nice dark music, but references to the devil are a red line for me. I mainly use 2xRoland 512 and 2xRoland 521 for 4 voice polyphonic structures. They are not predetermined to be evil.
Personally, I think you don’t know what you are talking about....
But good to know your red line :sb:
This is hilarious! :bang: :evil: :twisted: :hihi:

Yo-yo!

We encountered a bug in 1.2 firmware. When you set a new MIDI channel it doesn't get recovered properly. There's a fix for it in firmware 1.3

You can find it at our site: http://supercriticalsynthesizers.com/demon-core-oscillator/

I finally updated from 1.1 straight to 1.3. Polyphonic portamento is glorious. :love:

Edit -- First recording since updating. The DCO comes in at about 2:50 with a huge slow downward portamento slide, I love that it goes all the way up to 10 seconds.

It's nice when a module is so straightforward and easy to update.

Oh my.



There's a new playlist of something weird that occurred in the studio:
