do my outputs hiss?

[dr. orange]

hello!
I'm not sure whether it's the sounds I create or the outputs, but there are some unpleasant artifacts... How to find out whether the outputs hiss? If they did, would they also hiss on a low frequency sinewave or do you recognise hiss only with timbres that have a certain amount of high frequencies?

It might as well be aliasing, but I suppose at C3 as rootnote with untransposed oscillarots, the amount of alias is rather low

[Threlly]

I have heard some artifacts, but I thought they were there on purpose, part of the patch.
Other patches of a similar nature are free of them.

As for Oscillarots, nasty things, big teeth, live under the shed.
I'd put some poison down.

[jasedee]

Try switching the outputs and see if they still hiss...

[Timo]

Not sure, but the first things to check would be if the bit-reduction or sample-rate reduction effects (distortion + saturation) are used, and/or if Noise is used as an sound source, or whatever.

The bit-reduction feature, by design, gives off strange artefacts particularly during the late decay/release portion of a sound, if activated.

The FM control may also be a source of distortion/hiss, such as FM modulation via white noise, etc.

:lol:

Couldnt let that one go past unnoticed eh Threlly?

cheers

Blay

[dr. orange]

I compared all the outputs with the USB out in a blind test, and two times, I felt the USB sound a little bit cleaner, wasn't sure though, and one time, output three was cleaner... It's so subtle though and I'm not even sure, I think I can exclude any hiss...

That seems logical, yes!

But in my case, the hiss in the patch only occur in the VC, not via midi.
What do you make of that? :?

[Timo]

Maybe there's a troll hidden in your USB cable who doesn't like dodgy code passing through it. I'd unplug it and look down it, and use a knitting need to poke him out.

[rapidfire]

Yeah, that might be it, of cource!! :lol:

But seriously, have you ever witnessed anything like this, at a friends place or heard anyone claim this type of issue? :?

yes, this question is serious and if you make fun out of it, please tell me at least why it's such a stupid thought that outputs may hiss...

[Tomer=Trance]

its not stupid since it can happen dou to time,faulty manufacturing and few other reasons.
they should have used nuetrik... :D

did you contact access about this? im sure its not a big issue to repair if it is a hardware problem.

to make sure its not a software thingy ,choose an INIT patch then
turn the outputs to optimale level and patch volume aswell.
and run a sine wave. do you still hear hiss?

[rapidfire]

It is definitely the reverb engine producing this hiss.
It has decreased after the 1.1.1 update, but is still noticable when using the onboard EQ to harden the sounds to my liking.

I don't suffer from this problem in my KC, even if the reverb quality here is not as good as the one in the TI! :shock:

[Timo]

It isn't stupid, and it wasn't inferred otherwise, so put your handbag away. ;)

It simply meant I already shared all I knew, but after that I was racking my brains thinking of other causes, so the latter message was a cheap shot at the TI DSP coding as the next most possible source of the problem along with a healthy dose of irony. The issue needs to be corrected.

Is the issue USB or audio (using normal 1/4" jacks/cables) related? If the former, it's most likely a dodgy coding issue. If it's the latter, which soundcard are you using?, are you using balanced TRS cables?, are you hooking up the TI to a laptop?, and do you have any ground loops?
Does the hissing affect both USB AND standard audio-jack outputs?

[dr. orange]

it was on the analogue outs only, but pretty subtle... since I had to send my virus back anyways to repair the crappy knobs, I mentionned the hissing so they will fix it probably. I'm still not sure though whether it's hiss, but I didn't notice it on the USB outs...

[Timo]

What soundcard (or are you hooking it up directly to the monitors)? Are you using balanced TRS cables? What is your signal flow? ie. What pieces of kit are you routing it through, and is your gain structure set up correctly?

[dr. orange]

into an EMU 1820m using balanced cables, from the 1820m directly to the monitors...

[Timo]

How about if you bypass both the computer and soundcard and instead hook up the TI directly to the monitors using TRS balanced cables?
Use the same mains socket (using a trailing lead or adapter) for both synth and monitors in this case.

Just trying to narrow down other possible external causes first.

[Mayday Dream]

Im sure one of the distortion effects creates a small amount of noise in the background

[rapidfire]

In my case it got nothing to do with the output/ interference of any sort nor that distortion effect you're pointing at, but in all isolation, the reverb engine as a whole!
The quality of the reverb engine is obviously not yet sharp enough, simple as that.
When you have been working as a producer for a while you tend to notice artefacts messing with your meticulously adjusted reverb setting for a particular sound in a mix. The Virus TI ain't that new to me anymore, it has soon been 1 year with experimenting and fine tuning.

The intention of my question here was to see if anyone had come across this issue, but I guess by know noone really have as to continuous derailing answers!

Thanks for answering though. :)

[Mayday Dream]

That explains it then

To be honest i really dont like the reverb in the Virus and never use it. It sounds really metallic and strange.

[Timo]

I quite like the ambience reverb.

I don't have a TI, though. Only an Indigo.

[rapidfire]

Metallic....
Nah, you can't mean that... :?
What about the C models reverb, metalic & strange too?

I think it's on par with the best of TC, which means plugs like MegaVerb & Classic Verb and also the older reverbs from TC3000 & that one within Fireworx.
No complaints regarding the quality from my point of view.

PS: Metallic, well, Vanguards reverb is what I consider as metallic-sounding! :P

That means you'r out of this discussion or what...
Just kidding. :D

Yep, that reverb is killer on ambient leads/ plucks and of course stringy pads!

Yeah thats just how it sounds to me. Im using a Virus B but im sure the C is the same. Its ok i guess (miles better than vanguard :lol: ) but theres just something i dont like in the tone

I use TC Classicverb and really like the sound. Megaverb is nice but not as good imo

[rapidfire]

Yes, I totally agree!
I found the VSS3 to be the most convenient and best sounding reverb for most textures and musical styles, only if I could afford to have it installed permanently... 8)

Have you tried that CSR (Classic Studio Reverb Plugin) from IK Multimedia or that Blue Verb from Nomad Factory?
I was in search for some quality reverb plugs for my cymbals/ hi-hats and long crashes and other percussive effects type of sounds and thought these 2 in partucular might be useful for this, but I haven't had he time to try them out yet... :?

[JayTranzmit]

The VSS3 is nice, I tried the demo of this & was impressed. Love all the different room settings.

[JayTranzmit]

:lol: WTF??

How do I get rid of that baby pictue in my Av? :lol:

Is he squeezing the baby mustard

[rapidfire]

The VSS3 is nice, I tried the demo of this & was impressed. Love all the different room settings.

Yeah!
Pitty the price is well over 600 bucks! :?
Do you think it's worth this slightly high price?
It definitely is verstile and sounds extremely good! :P

[JayTranzmit]

Personally I think it's worth purchasing if you want those lovely tails on your verbs. If you look at it objectively, it's in the same price bracket as something like the Lexicon MPX1 although I do find it hard to justify buying software when you could be buying the hardware equivelant.

Depends on the set up & how you work. If I was software only then I wouldn't hink twice.

[rapidfire]

I see!
Well, I do own the Fireworx and the M3000, so would you consider this VSS as good as the Reverb 4000, or close?

[JayTranzmit]

I can't really comment on those to be honest as I haven't actually used them. The Algorythms used in the VSS3 are from their flagship reverb unit so they are going to be hard to beat.

I use the Powercore with TC Verbs & also own a Lexicon MPX1 which is routed via SPDIF into my set up, pretty much like using software. They do sound different & was why I bought the Lexicon, especially as this has the Lex chip which is dedicated to reverbs.

Not sure what to advise really, just go with what you feel I guess

[MADSTATION]

JayTranzmit: In terms of quality, how does the MPX1 rates compared to TC's ClassicVerb? I want a good reverb unit and was looking at the MPX1 since I'm not so interrested in getting a powercore card only for the reverb :)

[JayTranzmit]

Hi Madstation,
I quite like the sound of the Classic Verb. It's meant to be based on the Lexicon sound more than typical TC's, I think that's why they added the chorus type option. Can't fault it. I use it more so than the Mega verb to be honest, supposidly the classic verb takes more processing power to run even though it looks simpler on the face of it.

I'd say go for the MPX1 as it is good. The reverbs alone are really great but, the multi effect options really take it into other areas very well. Using large amounts of an effect doesn't wash out the sound or seem pasted over if you know what I mean. Huge verbs are superb & I did notice a huge difference when trying to get very small space/Ambience on percussion. The MPX definately shone in that situation & was actually quite surprised at how much difference. Just seemed more open & natural.

Using the Analog ins/outs, it is clean, although on some settings you can hear some artifacts with the converters. Mine is hooked up via the SPDIF & it as good as you'd want, pristine clean signal.

As an option against the Classic verb then yes it'd be worth purchasing if you're looking at hardware. Other than the MPX1 there is the TC M-One XL which has very good reviews & may be another option if you like TC verbs.

[MADSTATION]

Thanks a lot Jay:)
