Dual VCO / DVCO


#143

No, they don’t. https://en.wikipedia.org/wiki/Digitally_controlled_oscillator
And yes, the Four has DCOs. The Rytm has VCOs.

You don’t need to confirm anything by assumption, I’m telling you the facts here… :slight_smile:

Digital control doesn’t equate to DCO, as I wrote above you can send CV from a digital source - that’s a form of digital control. You have digital control of the VCF (Four/Rytm), VCAs… Etc… They aren’t DCF or DCAs because of that fact. The point being the system in its entirety - digitally controlled, analog sound generation.

Why was this advertised as being “available” when it’s clearly not the case? I mean, “WTF”


#145

time doesn’t really exist but anyway here’s a fascinating article re/ timing and tuning of oscillators etc …


#146

It still is.


#147

The source of my understandable confusion is quite clear, I’m not sure many folk were aware that the AR was different to its sister product in that regard, it makes sense now

thanks for clearing up this matter following my guess, we’ve all learned something I think, we’ll I have anyway :thup:

so DVCO is 100% legit then :wink:


#148

Explains why the A4 sounds flat compared to the RYTM


#149

@psyclone001 : The digitally controlled aspects of these machines dont affect the timbre; They provide stable and recallable tuning and modulation.


#150

Just in case you missed the discussion.
One has VCO’s, one has DCO’s
There’s a difference


#151

Yup, just pointing out that DCO vs VCO does not equate to flat vs. not-flat. (But of course I’m making assumptions about your definition of “flat”.)


#152

Yes you are :wink:


#153

I’d definitely take a release with Dual VCO, without having to wait for Overbridge.


#154

WIthout wishing to get further off topic I think the Filter (see here) has some bearing in the resulting often unpopular timbres of the A4, but i wonder if the oscillators in the AR are more pleasing due to their being simpler in some regards - either way the AR sounds lovely as a mono synth despite the voice/osc simplicity, the DVCO will surely be fun when it drops

I’m also not so sure that the charm/drift we appreciate from a traditional VCO is the reason why the AR sounds in some ways more meaty/satisfying given that its VCOs are somewhat on a digital leash for stability/control etc

I wasn’t aware the P’08 was a DCO which it seems to be - that’s certainly not remotely flat


#155

The Rytm has tons of low end and tons of distortion. I’m guessing this has much more effect on the sound than any difference between VCO and DCO.
Rytm also has sampling and while that is pretty much full-on digital, it also sounds ‘meaty’. So the sound of the Rytm seems to mostly come from the signal path after the oscillators/sampler.


#156

I found the P08 flat compared to the p6, or my old Polysix. That said I found the a4 mki flat and the mkii amazing. Well I shouldn’t say totally flat, it was still a gorgeous sounding synth, it just lacked weight and the overdrive was paltry but that’s all been fixed.


#157

I agree - there’s a life and presence to samples that seem to come alive … this means that the A4 should sound pretty impressive if we fire it through the inputs then surely :wink:

It’s clear that the analog designs have evolved AR>AK>A4 - I don’t know where the A4mk2 sits, but it seems to be ticking the boxes so that too suggests the ‘flat’ issue is not down to DCOs alone but to the other aspects of the signal path and in all likelihood the specs of the old/new LPF which is not present in the AR

Fingers crossed the DVCO comes before OB as per the DT compressor, that’d be a welcome gesture, especially as the DVCO was shown


#158

Countersigned.


#159

Amen to that!

All this talk of the A4 Mk 2 is making me a bit jealous. That DVCO would be a sweetener though!


#160

I agree. Especially since it was something that was advertised as launching with the ARMKII


#161

where is this thing already


#162

Dual VCO would be very cool … the mBrane snare drum machine has a dual VCO architecture and although i don’t know how “snare-drum” exactness it is capable of, some online demo’s have shown some really attractive sound design potentials for the dual VCO’s role in making organic rhythmical vibes.
