So, MX is indeed a very good sounding synth.chk071 wrote: Sat Jun 29, 2019 7:23 pmSure, but, the important thing is that the oscillator obviously produces a pure sine wave, while the harmonics, thus the reason why the sine wave isn't pure anymore, seems to be the filter. So, if you want to judge whether or not the oscillators produce a pure sine wave, you need to deactivate the filter to do so.pdxindy wrote: Sat Jun 29, 2019 7:18 pmAlso, perhaps filter is not quite the right word. It makes people think it is not a Sine and then you are having to add a filter to make a Sine which some can see as a workaround or not the 'real' thing.chk071 wrote: Sat Jun 29, 2019 7:13 pm Again, maybe you left the filter on. The filter adds harmonics, so, it won't be a pure sine anymore, obviously.
One could also look at it from the other direction. It is a Sine wave and there is a subtle waveshaper that can add harmonic content.
I've seen 2 videos now where people didn't do so, and wondered about harmonics, which they called "aliasing" while they aren't. Man, what a mess.![]()
But I do believe that it has been shown that the osc, without use of the filter, does produce some aliasing, or something, that does not look like harmonics, because the peaks are not evenly distributed from the fundamental. Responses keep emphasizing that the filter needs to be deactivated, but it has been. Other responses are that it is an artifact of the wave table. Others that it is intentionally not a clean sine, because people don’t want a clean sine.
But the point or value of a clean sine in this case, is not the “pure tone” of the wave form, but rather the ability to avoid unexpected and perhaps unwanted behavior when leveraging the modulations, and/or when using distortions - the former being one of it not the key strength of MX. It’s not clear to me that the fact that the aliasing is -130db or below the noise floor doesn’t impact the behavior that low level aliasing has on audio rate modulations.
Again, sine, bypassing filter in routing, exhibits this behavior. Standing alone, aliasing is too low. It may lead to unexpected and unwanted behavior when taking advantage of MX powerful modulations.
