Xhip vs Analog Hardware

[Mutant]

Nope, for it to be filtered requires it be filtered.

So there must be a 2nd filter on the Sub37 or maybe errissa made some mistake when recording the samples.

Possibly.

If the effect were in the [*] oscillator core as I said it's a bit complex to figure out exactly what would happen without knowing exactly which circuit is used. It is entirely possible to create a low-pass filtered raw waveform, although it is easier to just low-pass filter it elsewhere after the fact. Either way it is a low-pass filter of some order at some frequency.

It might be due to the audio interface too, or who knows.

edit [*] corrected typo "filter" to "oscillator".

And i remember having to close the filter a bit too when matching a square wave from this set:

And a quote from the description:

48,000 Hz 24 bit recordings of Waveforms from the oscillators of several synthesizers with the filter wide open and no resonance.

[conspiracy mode on]Maybe this is the secret of the mythical "warm analog sound" ?

I fail to understand your excitement because that simple single note does not say much about the sound of a synth. My old SynthEdit synths sounded the same...

It is a !*>>>Moog<<<*! oscillator !!!
You can't call yourself a synth nerd if you aren't excited about it !!! LOL !

And as i said in my first post here:

Of course just the oscillator doesn't make a synth and if i wanted to match the filter i would probably not get so close, but still... it is a perfect match of a Moog oscillator on a freebie VSTi.

My old SynthEdit synths sounded the same...

Oh so we had perfect emulations of Moog oscillators since almost always ?
I highly doubt it.
I remember these old SE synths.

[fluffy_little_something]

I like synths, but I sure hope I am no synth nerd

Perfect emulations of Moog oscillators? Didn't you yourself say that Xhip doesn't even try to emulate Moog, yet does it perfectly as you claim? Why wouldn't that apply to other synths as well...

Also, with Moog you pay a lot for materials, labor, shipment, the brand name, etc., so you should not expect a Moog to sound much better than a good soft synth just because it costs much more. If the sound is all you are after, a good soft synth will do as well.

Yes i claim it.
Listen to both clips again if you disagree, download and use all your visual diagnostic tools on them.
But keep in mind that i did not try to emulate the "80hz hump", so it is not there on Xhip clip.

Oh, I believe you (benefit of the doubt, I am too lazy to do those tests), I just don't share your excitement, even if it were a 100% match.

It is not a test, the answer is in the names of these files:
FirstXhipThenSub37
LXhipRSub37
So you don't have to guess anything and then be embarassed of being wrong (like i was in that Diva thread).
It is not made to prove anything except the possibility to emulate analog with digital in 2015.
And probably other modern soft synths would go about as close too, but with some heavier equalization.

[fluffy_little_something]

Oh yes, spare us another "guess which is which - based on patches that don't even try to sound the same" thread

I listened to your first file, since it is only one note, you seem to have fused the two sounds somehow, without any blip, well done

The seam is exactly at half of the total length, no crossfade, just glued together at the right place to avoid the click.

Elo again.
This time it is Xhip vs Jupiter 8.

Found this nice video.

The description says the synth is connected directly to the interface without any effects (i love such raw uneffected analog synth demonstrations on YT).

I liked the sound at 0:59 the most, so i tried to copy it with Xhip.
As almost always left is Xhip, right is the analog.

(Click on top right to download).
Couldn't get the envelopes right, maybe because they are more linear on the Jupiter and i am using Xhip with nicely curved exponential envelopes.
But the timbre is almost there IMHO.
Boosted some 350hz by ~2 decibels to match the spectrum better, the filter response curve is a tiny bit different on the Jupiter.

And this time it is not a perfect match like earlier with that Moog oscillator, it is just good enough for me, for fun from playing with that sound.

[fluffy_little_something]

Sounds more like the left hand/bass on the left side and the right hand on the right side. I don't have a balance knob on my speakers

Anyway, the Vangelis sound is a typical sound where good oscillators and filters become evident. One reason why I like Sylenth, it does such sounds very well, even with just two single saw waves and without any effects. The only thing typical of the J8 Sylenth lacks is the iconic sync sound and normal PW control. I hope they will add that sooner or later.

OK so this time i am not trying to match it anymore (just normalized both to 0 which ofc didnt make them equally loud), i wanted more "grit" and "growl" on the bass.
Not a L/R split this time, first is gritty, growly Xhip, then smoother and little bit less agressive Jupiter.

I like this sound more, i am not sure why.
Maybe in my mind it sounds like it is overdriven by some vintage vacuum tube device, while it isn't.
This of course doesn't mean that i like Xhip more than Jupiter (they have different strenghts and weaknesses) - and i would have to put my hands on the hardware to check if that grittyness was also possible there.

[fluffy_little_something]

I think you might change the filter key follow, the filter seems more closed on lower octaves on the Jupiter.
Additionally, if there is a key follow control for the amp, it might make sense to make the lower octaves louder relative to the higher ones.
The detuning might also contribute to the different roughness.
