u-he Repro (Repro-1 & Repro-5) released

[fluffy_little_something]

Well, whatever it is, it sounds bad to someone allergic to distortion, and again, why is it only on one octave more or less (g3 to a4)?
And why would the filter care whether its input is 0 or 7 semitones apart?

Because distortion will sound different depending on harmonics, waveforms, all kinds of things.

Welcome to a real analog synth.

Also, let me say, using distortion, I have programmed some ugly sounds out of this thing and sometimes just at certain octaves.

[fluffy_little_something]

Distortion as such was off, by the way. I was not speaking of the distortion unit.

Well there had to be something on for it to behave that way. No FX at all?

[fluffy_little_something]

No, I turned all effects off. Can't you hear it with that patch I mentioned? I don't expect you to just believe me. If you have Repro you should be able to hear it as well. Maybe I am just overly sensitive when it comes to that...
It should also be visible on an oscilloscope I suppose.

That's the point, one can't turn that saturation or whatever it is off. In Sylenth1 I have my Drive knob in the filter section, which leads to a similar result, but on all octaves and with all waveforms, and only if I want to. That's why I found the rather selective nature in Repro strange. Also because I know that noise from other synths such as Spire and Predator. Do they all use the same algorithms?

I don't know the original hardware, maybe it behaved like that as well.
But as much as I disliked my JX-8P, it did not have that noise, despite being an analog synth as well.
I will test the PG-8X tomorrow to see how that emulation behaves.

It's not noise. It seems like beating between the two (analogue-modelled) OSCs, that gets more pronounced at certain PW settings and in certain ranges. Doesn't even have to do with "some semitones apart" - it's there even with both OSCs set to same pitch and even with both at saw-tooth. Obviously it just crosses the threshold of your annoyance in certain ranges. Modulating PW with the LFO doesn't help either, because it "scans" through the "bad" range all the time.

I guess, the patch was designed to sound good at low and mid range - as simple as that. ("Doctor, it hurts if I do this...")

Okay, I pulled up the patch and played it all the way up and down the keyboard. Not only don't I hear this grinding you're talking about but at way upper registers I don't even hear any aliasing which really surprised me. Damn, this thing is rock solid.

Only thing I can think of it's one of 3 things.

1) You're not using the release version so it could be something that was fixed.

2) It's your computer. It can't handle this plugin.

3) It's your ears.

I don't know what to tell you. Patch is absolutely perfect on this end.

1) I am using the latest demo version I downloaded 3 or 4 days ago.

2) No, according to the Windows Task Manager one chord only uses about 7 % when I use Reaper.

3) While my hearing is not what it used to be 30 years ago, the problem is that I no longer hear everything that is there (i.e. things beyond 13 kHz), and not that I hear things that are not there.
Maybe it is your ears that don't let you hear what I am talking about. After all, when Urs says it might be the filter saturation, then you should definitely hear it as it would be a feature.

[zvenx]

Or maybe that which you hear bothers you and not others.
Like I find Kenny G's saxophone bordering on torture, whilst others find his playing melodic etc.

May just be your personal taste.

If it really is filter saturation what you're hearing, I'm pretty sure that's how the original unit behaved as well in those cases.

[fluffy_little_something]

Just played around with my Toneboosters EQ, which has an analyzer mode, but I am not sure how to interpret it. Anyway, on the left is the chord with +7 detuning, on the right without any detuning. Maybe it is the bump in the red square that I hear? The grinding noise is certainly lower than the chord as such.
(There is also a lot of low frequency content in my view, not sure why that is...)

I have similar feelings with The Legend's drive circuit. I think applying it ruins the sound. Whereas DIVA sounds nice, & Monark starts to sound beautifully aggressive, The Legend makes me wince when I start applying the drive. The ugliest drive in a synth I've heard. Nobody else mentioned it, so neither did I, & simply moved on

[fluffy_little_something]

Just for the sake of completeness, here is the same 2-note chord with and without detuning in Sylenth1, there is no bump...

But again, not sure that is what I am hearing...

[Chris-S]

Strange thing: Like with Spire and other synths I hear an ugly grinding noise in Repro 5 when using two oscillators that are detuned by several semitones.

Confirmed. I think I'm also able to hear it although my ears have a treble drop.
Like Urs already said, this is an effect of saturation.

Analysis in Span (note B6, FX and PWM off):

I don't remember that, is the drive in Legend also hardwired or can it be turned on and off?
