By the way, I'm not able to update to 3.8 within Fathom on Mac. I says it's checking for an update but never does anything else. Mac Monterrey, Bitwig 3.2.

You can't run the settings update from a Mac it will not allow socket communication.
You'll have to email support.

I see, thanks. I did do that and was told to update in my DAWFathomSynth wrote: ↑Mon Mar 21, 2022 2:32 am You can't run the settings update from a Mac it will not allow socket communication.

Plus I just got a response with broken links to 3.7.-

Sorry, I accidentally sent the old links to 3.7.
I just updated everyone who requested new links to 3.8.
Keep in mind there will be yet another new release to fix the bug above.
It will be version 3.82.

Version 3.8.2 is released.
It fixes the spectral modulation dials on the right not working which control the partial ranges.

Fathom Version 3.8.3 is released.
It just fixes the bug in spectral modulation where the partial range dial could not be modulated.
The dials on the right hand side can now be modulated correctly.
Also here is information on spectral morphing.

This patch of mine with the metamorphic OSC shows 60% CPU (one voice) with spectrum mod on.
Turning Intel Parallel CPU off or back on doesn't change CPU usage.
Anyone wanna try it and confirm what I'm getting?
Don't change the amount of voices, it overloads here (Intel Core i5-9600K)

You have all 8 detune voices on, phase on, spectrum partials on max and every possible metamorphic feature enabled plus oscillator distortion. Of course you are running out of CPU. Was this an experiment to see if you could run out of CPU?
I tried to clean up this preset and bring the CPU into a reasonable zone and discovered you literally have everything enabled. You have shape shift, expand, overdrive, multiply, which will literally leave nothing left of your original waveform except one big wall of aliasing. Then on top of this you have eight detune voices, phase enabled, impulse enabled, ripple enabled with expand on, chop enabled with both width and frequency modulated to the extreme limits. Then on top of all this you have oscillator distortion turned on (you would need more distortion at this point?).
With all due respect I can't understand what you were trying to do with this preset other than to see if you could make it run out of CPU, which obviously it does.
Spectral modulation is a subtle effect. You have every possible metamorphic feature turned on so there is literally nothing left of your original waveform except a digital wall of noise. There is no way you are going to be able to hear spectral distortion at all if there already is so much distortion present.
Fathom does not manage CPU for you. You have to do this yourself. Spectral modulation is an extreme CPU load and you have it added to an oscillator which is already overloaded in every possible way.
Please read the manual chapter 11.
I would strongly suggest that you start from scratch with 3 detune voices and the middle voices set one octave low if that is what you really wanted. On the phase page just turn up Volume Phase. Turn on only spectral phase modulation and set Partial Max to 50 because you won't be able to hear any partials above that anyway. Then gradually dial up just a minimal level of either oscillator distortion or chop, but not both, until you get just the level of harshness you want.
For instance:
https://static.kvraudio.com/files/3302/ ... preset.mp3
That preset runs on my system at CPU 35% and it will probably be a little less on your system.

I think RPH'S point here is not the 60% usage but:RPH wrote: ↑Sat Apr 02, 2022 3:37 pm This patch of mine with the metamorphic OSC shows 60% CPU (one voice) with spectrum mod on.

I think RPH expected this:
- turning off the Parallel CPU setting will increase the CPU consumption
- and tunring it on again will reduce the CPU consumption
Don't know whether this is the correct behaviour or not....

that is indeed how i also read it, it seems AVX only kicks in for unison?? but i can be wrong.] Peter:H [ wrote: ↑Mon Apr 04, 2022 4:54 pmI think RPH'S point here is not the 60% usage but:RPH wrote: ↑Sat Apr 02, 2022 3:37 pm This patch of mine with the metamorphic OSC shows 60% CPU (one voice) with spectrum mod on.

the presets i make, aren't that CPU hungry, well it still it eats a lot of one core, multithreading seems to be, well i can only compare it the best with Biotek2, you see multicore kick in, quite well (but all cores, so that is not always a good thing), but Fathom Pro/Vector really relies very much on one core.
and if you make your own presets, and other soft synths have it also, you must always consider the cpu load, of your own system, gladly.. that is quite capable, or very capable.
turning AVX(2) on or off, has no real influence. but i believe it is stated on the website, that it is for detuning, multiple voices.

Indeed, that was what I meant, but as Wasteland also points out Intel parallel CPU option only works for detune. Odd thing is I didn't see any difference in CPU usage, detune being on and using 8 voices of set to off. The combination of detune and spectrum mod on seems to do that?] Peter:H [ wrote: ↑Mon Apr 04, 2022 4:54 pm

@Everett:
Your response really cracked me up haha
Guess it's a generation thing? I don't think it's a wall of noise, it sounds great and doesn't alias at all. The combination of Detune and spectrum mod makes it sound fat. Just play one low note continuously and do some short octave notes on top, and combine with a good hard beat.
Reducing CPU wasn't my intention, but changing the detune voices from 8 to 7 and back to 8 saves about 10% CPU. Keeping detune voices on 7 saves about 50% CPU, but makes it phazy.
Turning off spectrum mod saves about 70% CPU, while keeping detune on at 8 voices.
Cheers guys.
