Thanks man. excited for the next episode! i got a peak for a couple of weeks now and i'm loving it. we'll see if you found things in depht i didnt explore so far ;-)
Here is also the article that explain what a NCO is. It is also not a synthesizer exclusive concept. NCOs are widely used in industry for very high frequency oscillators. en.wikipedia.org/wiki/Numerically_controlled_oscillator Last thing, the "oversampling" you are referring to is in reality the step frequency in an NCO. So it means that you tick 24 million times per second and create a new value in your NCO. The second thing you need to get to quality is how big the biggest number in the NCO is (e.g. how many bits is your accumulator), before it runs over. Both together and the DA circuit gives you then a very fine analog output, that you then put into the signal path. So to have enough bits for your 24 mhz, you would need 25 bits (32M possibilities) and a 25bit DA to get all that into resolution. There you have it - and that is what it is about - the quality of the analog output is so high, that you cannot hear any difference anymore with out limited hearing capabilities as humans. If you ask you dog, it might have a different opinion on this ;-)
A bit of nomenclature mishaps should be cleared up. When you say "amplitude" is analog, you really mean VCAs instead. Amplitude as a term itself bears no relation to being analog or digital - it just is. Also, NCOs are NOT a "physical model" of an analog oscillator. That is just wrong. It's basically a counter into a DAC, that's all there's to it. NCOs have been also used in Modal Electronics 002 synth, there's a video where Paul explains what NCO really is. Look it up, please. This is not about oversampling at all. Also... look at Korg Minilogue... it has VCOs and all waveforms on them can be shaped (so, saw and triangle as well as square). This is absolutely not a special thing about NCOs at all - waveshapers exist in the analog realm as well, and can definitely be used on VCOs (and they have been, since a long time, because an analog waveform usually has a saw or triangle core, and other waveforms are produced by means of waveshapers)! You can definitely do a triple saw from a single osc thing with regular analog oscillators. It's just a matter of waveshaping it correctly. However that does demand more circuitry so making it more expensive in the end - which is the real reason why it doesn't appear very often. Not because it's not possible to do that with VCOs!
Novation should pay you! Love the Peak but not cheap. I love analog, but I was thinking that at a point does’nt all analog become digital when we record? Or I have to get my old cassete player from my atic! I hope the peak did’nt fall on you hand? You are without a doubt “The synth guy” . Greetz 👍✌️
Lol. Actually the NOVA synth engine found in the Circuit is mostly the same as the PEAK, except the fact that the filter is analogue and the CPU is not as powerful. Still the Circuit can really kick it!
Nu-Trix The Synth Guy Numerically Controlled Oscillator, Would this be, like Parameter(ie. pitch) Limits and functions found on software/hardware from old Chip-tune Consoles from ages past... OR would this actually revolutionalize the Peak (for making chiptune sounds:) Plogue Chipsounds s3.amazonaws.com/chipsounds/chipsounds_guide.pdf I found some interesting tidbits in the guide. Thanks Nu-trix!

There's a pack of dogs somewhere listening to the Peak and barking "Nah mate, sounds too digital."
Same old story.
If you did the blind test on them they would say the CS-80 sounds more digital than the Peak.

How easy it is to glaze over the words "Korg Minilogue" and interpret it as "Kylie Minogue".
That’s what I remember Modal Said they used in the 002

No the hand is from a stupid accident. It seem that I’m unfit to CrossFit. ;-)
Just threw away my Circuit. It has no NCOs. 😀 ... actually it’s so relatively simple, and even with that I’m over my head, but learning!
