Cherry Audio's CA2600 is available NOW!

oh cool, thought it must be doable as it’s their tried and tested virtual modular routing

According to the developer these artifacts are part of the noise floor , I don't buy that

[EvilDragon]

If it were noise floor it would have looked different on the scope. Not buying that either.

why does it sound so dull?
can't be my old ears
remember arps being quite bright/brash

Going from 48 > 44.1, however, sounds terrible unless you invest a bit of CPU elbow-grease in proper dithering.

*cough* ... dithering and sampling rate?

If a synth does sample rate conversion it points to basic flaws in the implementation. You have to adapt any filter/oscillator/vca to a given sample rate anyway - that does not ever need a conversion!
The only point where it could make a difference is if you use a table for the oscillators instead of modeling them and have a bad interpolation and/or low resolution of the table...
I mean as an instrument I do have fun with this and its even more inspiring than the competition. Better they call it „inspired by“...

If you internaly run a synth at a different sampling rate than the DAW/host. Then you have to do SR conversion after all the internal processing is done simply because you have to hand the audio to the DAW at it's own sampling rate. And if that conversion is done correctly, the synth should not produce any audible artifacts that are not there before the conversion.

The conversion is as CPU intensive as the sharpness of the filtering it uses. The sharper the filter cut, the less the artifacts. (as opposed to a smoother cut were you would have to contemplate between having more artifacts or a duller sound with a lower cut).

Now reducing that CPU usage is the hard part here. And its a sign of how skilled the dev is.

Man , it aliases like hell
Here's a file , osc 2 is tuned to 16 and plays a saw at E7 ..NOT synced
Second part of the file , now osc2 is synced to osc 1 ( also tuned to 16 ) , only synced oscilator 2 is heard
Changing sample rate does not improve it at all , this is getting so worse

And this is how TALmod ( by togu audio line ) sounds , no aliasing at all

Coming from my side, as a developer, it wouldn't be nice nor credible if I judge another dev product. As this can be seen as a business attempt instead of an honest opinion.

But generally speaking. ANY decent analog emulating synth shouldn't have seriously audible aliasing. One of the best ways to confirm an artifact is actually aliasing (and not something else that is part of the intended sound) is to modulate the PITCH of an oscillator with an LFO (or something). If you hear noisy zipper sounds that go down and up in pitch, then thats a good sign of aliasing. No analog synth does that. You'd see this in a spectrum analyzer as many many low amplitude harmonics that continuously go up and down in pitch.

Edit: sync would emphasize the artifacts further.

The saddest thing is that it's actually a verry fun and inspiring synth to patch , and that's where the emphasis is , not on audio quality ( at least not at the moment ) .
You could forgive them for jumping on the 2600 advertising wagon , but atm there are just to many quality issues .
I genuinly wonder if voltage modular standard modules have the same sync aliasing issues
Here's another example , osc 3(saw) synced to osc 2 ( one octave lower )
Osc 2 set to square and slighty pitch modulated by lfo
Only osc 3 output is heard
First cherry audio , then talmod

Before anyone comments that they don't make music for bats , that is not really the point

This is an excellent overview of how sample rates actually affect audio, and when/why you might want to use a higher sample rate.



The same guy made a great video about dithering too. Dithering only applies when converting to a smaller sample size — for example, bouncing audio from your DAW (most of which run at 32- or 64-bit) to 16-bit. Nothing to do with sample rate.

The CA 2600 sync aliasing issue is NOT resolved by a higher sample rate , that's the big stinker .

All of Dan's videos are awesome. Check the tutorials he made for U-He or Tokyo Dawn Labs, too!

man, this gentle divider guy just keeps bombarding this joint with heavy artillery, ain't he? what savage.
