Synapse Audio OBSESSION is now available!

don't mind the colors too much, besides the less/more pronounced resonance behaviour from one to another, I didn't match the sounds too much but just I wanted to see the envelope shape

That attack looks *weird*. What is this, high reso filter sweep with envelope?

[urosh]

I wish every soft synth reported actual time values for the ADR stages of envelopes instead of 0–100.

For analog envelopes (and analog behaving digital envelopes) that would be no can do. While there is well defined time of attack phase, decay and release settle down somewhere around infinity (well, in theory of course). You would need some kind of convention, like, decay/release time is time after which envelope value/voltage settled to 80% of theoretical final value, but there is no such convention. Same issue with compressors, every manufacturer has it's own idea how attack and release times should be measured/defined.

How do you make these graphs? Does that show all the possible values for each of the time stages? If there’s a simple way to measure and visualize the shape of envelopes I’d love to know about it.

A spectro/sonogram is what you need.
Preferably stereo to compare 2 signals on the same window:

Or offline standalone:

Then you just set your resoance to some very high value and tweak the filter frequency, filter envelope modulation amount and envelope times.

Ranges are definitely very different

As far as shape, they seem pretty similar (i.e. not as much of a difference between linear and exponential)

Not a "very scientific" or comprehensive test.
It was just a max-resonance filter sweep run through a spectrograph with "matched-by-ear" envelopes.
Just for the overall shape.

After your post, I just got curious to see if the envelopes could differ to the point of one being linear and the other being exponential.

let's forget that for a moment, and just enjoy Obsession as it is, regardless of the closeness to the original. The OB magic and character is well recreated there, IMHO.

Maybe I’d change my tune if I ever got to play a real one, but I kinda don’t care if Obsession sounds exactly like an original. It sounds good enough to cause me to lose track of time while I’m playing it, and that’s all I’m really after in an instrument.

It also has numerous features that make it more powerful and expressive than the original, like a mod matrix, aftertouch, and even MPE. The real one doesn’t even support velocity!

[Yorrrrrr]

Yes!

I have put up a bank of 80 (free) patches for your delectation. Most of them are rejects from the factory bank but it also includes the few that are in there, with enhancements (to utilise features that were added later in the beta process). To plump it up to 80 I also created a few new patches using Orion's Genetics feature to get them started. That's where the weird shit happens.

Most of the leads and drones plus some of the pads, are in the darker/heavier style you might expect but a lot of the rest of them aren't at all so there should be sounds in there for everyone. Going through them this morning to level the outputs and make sure it wasn't too samey, I was surprised a few times by how huge OBSession can sound without having to use Unison. It's really quite amazing, probably a bigger single voice sound than any other synth I have access to.

Have at it - https://www.kvraudio.com/banks.php?s=one&id=3440

Thank you very much for these presets Bones, greatly appreciated!

My pleasure!

a compressor would totally not have any effect on the frequency of the resonance peak.

Neither would the envelope. An envelope is a modulator, it sits outside the signal path and, therefore, doesn't affect the frequency of anything. So your issue is with the filter, not the envelope.

Did you play with the voice trimmers? The whole thing with the OB-Xa is that the individual voice boards all sound slightly different and the variation can be more than just subtle so unless you had the exact instrument used to create that sound, it might not be possible to get it exactly right. Ever.

To see what I mean, create a short looping pattern in your sequencer and let it run. Load up a bass patch in Obsession. Now right-click and randomise the voice adjustments. Hear how different it sounds? That's how much variability there is in each of the 8 voice boards in Rich's OB-Xa. But that's what we love about these old pieces of shit, isn't it? So that's what you get.

Do we want a perfect emulation or not ?

I don't want an emulation at all. I think it is the saddest, lamest, most pathetic thing imaginable.

Why are you so agressive defensive about it ?

See above.

It is a small thing even most gearheads here apparently can't hear that would be fixable in less than 5 minutes.

I am confident that if Rich did it a certain way, that's because it is exactly the way it is on the actual, real, hugely expensive OB-Xa that he bought for the purpose of modelling. I have known him for more than 20 years and he would never have allowed anything like this to get through. If it was a matter of a few minutes or a year to get right, he wouldn't be satisfied until it was perfect. It is why he does it.

Are these individual voice settings offsets static or dynamic ? If static, then it is totally not what i was talking about.

I wish you'd make up your mind. One minute you want a perfect emulation, the next you want it to behave entirely differently to the way a real OB-Xa behaves. And I answered your question exactly as you asked it.

You should know by now that trying to offend me will only backfire...

As long as you understand that the longer you carry on like an idiot, the more it looks like you might actually be one.

I am not struggling with anything, but I consider it my duty to point at inconsistencies.

What, did teacher make you Inconsequential Details Monitor for the month? Did they make you sign an oath of office and swear on the bible?

But since correcting other people's mistakes is part of my profession, things like that stand out like a sore thumb.

And yet you failed to notice all the misaligned labels or that the Mod Wheel isn't a wheel at all, it's a slider. Maybe it's time someone else got to be Inconsequential Details Monitor? You're obviously not up to it.

An envelope is a modulator, it sits outside the signal path and, therefore, doesn't affect the frequency of anything.

Filter envelope very much affects filter cutoff frequency when applied. And Mutant is talking about filter envelope behavior.
And he might be onto something and it's not subtle at all.

Indeed, that is where the filt.env is for. . .

Looks like it didn't take long for some people to break out the microscopes and look for every tiny imaginary flaw.

Oh well that's the difference between musicians and nerds, between those who play synths and those who play with them.

BTW Here is a quote from that guy on GS i was talking about earlier:

You are welcome to use Synth1 to play your Oberheim sounds if you don't care about the tiny details.

Because as we all know, in the context of a mix, most people couldn't tell the difference between Synth1 and Sylenth1.

One day, I'm going to post a contest over at Soundware to name the synths and watch everybody fall over themselves trying to get even one right.
