Howdy, I stumbled upon a rather interesting take on the Radias MMT synthesis:

http://blog.zacharcher.com/2011/03/04/dissecting-the-korg-radias/

of course this is not a proof that radias uses samples instead of real oscillators but if it does it's quite disappointing

Edit: of course i know that samples can be used as oscillators but in the case of such stuff as square/triangle/sine wave etc you'd expect to find an algorithm generating the sound.

Anyone has ideas what could be causing the cutoff and aliasing effect in radias?

omfg this article again, its total horseshit.

Wow X-Trade...I searched for that discussion but I couldn't find it...

Even if the oscillators were samples, what would be the difference to a mathematic formula? Even the first organs oscillators, that had a set of sine-shaped gears rotating in front of magnetic pick-ups are a kind of samples, the mellotron is also a sample player (magnetic tapes).

Any method to bring something to oscillate is valid, even samples. Important is what the oscillator outputs.

I personally would prefer sampled oscillators (provided it has a good interpolation algorythm) to mathematically or physically generated oscillators because they provide the possibility to create any waveform you want providing more variety in what is the essence of every synth.

Another thing worth pointing out is that the Radias/R3 engine lets you alter and modulate the shape of the waveform for oscillator one. Things such as pulse width modulation would be hard to replicate with a sample based waveform, which is why you don't really see this feature on ROMplers.

I'd like to point out that the author of that blog post has never acknowledged or discussed the major errors he made that we revealed, nor has he posted any follow-up entries to his blog or here. If he's not "man enough" to even acknowledge his errors, then he's the last person you should trust to evaluate the Radias. He was merely trying to find a way to justify his own incompetence in getting the Radias to sound the way he wanted, and he never demonstrated any skill or knowledge about synth programming, whatsoever. It's total BS wrapped in enough techno lingo to sound credible on the outside, but it's like crap wrapped in a Christmas box.

He had posted the same thing over in a real music forum and a bunch of people pointed out that he was wrong, but unfortunately, his personal blog post about it pops up easier on a Google search which contains no corrections. Probably just deleted whoever tried to debate it.
