Aliasing oscillators?

[Joey]

the supersaw wave, as well as eat pulse (pulse wave replacement) and sine wavetables dont alias anywhere near as much as the classic oscillators

honestly i haven't noticed much in the way of aliasing. TI is by far the best experience I've had w/ a VA in that regard.

"anywhere near" i don't understand. do you hear aliasing when using the Sine wavetable?

sure, my TI2 might have more aliasing when directly compared to other synths, but i'm also making more melodies with the sweeter sounding TI2, go figure.

Well, it whistles at an unwanted additional frequency when the pitch is modulated with an LFO and the TI is plays a high note.

could you please supply a patch which illustrates that?

thanks, marc

i should have just said there isnt any

A pure sine wave is the one waveform that you would ordinarily expect would never give rise to aliasing. The fundamental frequency is the only frequency component in a sine wave, so unless you attempted to set the fundamental itself to greater than the Nyquist frequency (and that's ordinarily impossible due to the range of MIDI notes), you should not be able to cause aliasing using only a sine wavetable.

It is the waveforms that have frequency components higher than the fundamental frequency, i.e., anything other than a sine wave, where aliasing becomes a possibility, ordinarily.

Well, it still could be artifacts cause by interpolation, since I don't expect that the virus is doing the additive synthesis needed for wavetable synthesis on the fly.

@Marc

Patch as described, it was the first thing I tested when I got my TI about 2 1/2 years ago, all saturation/distortion functions set to off, but haven't rechecked that for a while,...

Can anyone compare the the sound of the Virus oscillators at high frequencies to the Nord Lead 2x? I have a Nord and have never noticed any issues with its sound at high frequencies.
