Horrible aliasing

Post by gentleclockdivider » Sun Nov 15, 2020 2:07 am

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 :hihi:

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

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

Ouch. Is this at 44.1 (which SHOULD sound fine, despite what some folks say)? Does it sound OK at 48?

Sounds equally as horrible at 48Khz .
It's beyond acceptable
I guess some folks just don't have a good set of ears , or think it's supposed to sound this way :lol:

Truthfully, and not as a criticism, many people just think synths make weird sounds and don’t realize (and sometimes don’t care) that these are not analog synth sounds. I wonder what serious reviewers are going to say about these issues? The initial reviews/articles sure sound like puff pieces now.

Hi,

Not sure. I passed your comments along to them. I suspect that your definition of "horrible aliasing" and theirs might differ.

But as you might already know, we're always looking to improve our software, as evidenced to our response to your earlier comments on a couple of other issues.

Osc sync aliases when playing high notes , no matter the sample rate
Point the developers to the uploaded sample I posted earlier
