NOISEand CRACKS and ARTIFACTS in sound when transposing a single WAVEFORM !!!

hey !

I have a problem with my Ti2 . Actualy speaking with virus support but no answer at the moment , first they answered me fast and now i am waiting answer for about 6 months

My problem is extremly easy to explain , no need to import an audio file here , but if needed i can do it . I really need someone to try it and tell me if the same noises occurs .

I use the most basic preset , a simple sound init , only osc1 with a sine wave , no effects , no lfo , no filter enveloppe . High pass filter . no amp , no enveloppe , just do nothing and use the most simple waveform .

Then , while playing a long note , when i start to use the semitone knob , i have a very anoying noise on the high frequencies , you can not hear it when you pitch down ( of course , because of the high pass filter ) , but anytime you pitch up , the noises appear . Then , if i put a single lfo on the osc 1 , same problem , the noise appear when the wave go up , making the sound very dirty .

Its not only happening with sine wave , with other waves form as well , but its easier to listen with a single sine wave . It happen with other kind of filters too .

As well , when i turn the knob of the high pass filter cutoff , same problem but lighter .

Seems , any change on a long note applied on the high frequencies produce this note .

And im truly asking myself if its my virus ti2 having an issue , or if this problem is a factory problem and everybody have the same noise when doing this .

Its actualy a big problem for me , cause i want to make a very long high frequencies pitched note on my track , and i cant have it clean .

I tried everything . Smooth on is not the problem . Factory reset is not the problem . I tried by usb , analog , virus control , same problem . My system is totaly clean , my nord lead with same config make me zero noise . I tried with midi usb , or direct midi cable , same result . I tried factory bank reset , no result . Punch dont do nothing . 44000hz or 48000 hz same issue .

My knobs are not the problem , they work perfectly fine and dont produce noise , im sure of this because the noise appear the same way when i use only virus control VST .

It mean , i can apply any lfo on a single sine wave , or use semitone transpose , or move filter cutoff , withotu producing noises . Thats totaly weird .

Same issue with all oscillators 1 , 2 or 3 . Same issue producing the long note with a long decay and release , or writiing a long note in the sequencer .

I tried with ableton 6 , 9 and 10 , same issue . I tried with emu soundcard , rme babyface soundcard , virus soundcard , or computer soundcard , same problem .

Even if i play the note , and then totaly disconnect the virus from all his cables , then the note keep playing inside the virus , i move the knobs and same problem .

Same problem with headphones output on the virus , analog outputs , or midi audio .

Its driving me crazy .............. HELP HELP HELP PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

a 1800 eur synth where i cant use a single lfo on a sine wave ? or transpose a note in real time , with no crack noise ????? thats weird , and not normal .

Sound init with 0 modulations or effects is the most simple patch ever , how is that possible ?

I use a lot the semitone modulations , and now , i cant work . Not sure if that was happening before , i guess yes , but as i was using more complex patchs , i never listen to this noises . And now i just want a single sine wave pitched up , i cant do it .......... With more complex patches you cant listen to this easily , but its here

Anyone can try it please ? I realy need other people to do a test because virus answered me 6 months ago it is a normal behavior from virus engine , so , i abandonned the idea to got it fixed . And i stopped to use it , because if i cant do the most simple thing ever on this synth without damaging the audio quality , i prefer not to use it .

Thanks for your help guys !!!

answer from Access :

Dear Ben,

We can exclude a hardware problem on your unit here. The same happens here also on the TI2 devices we tested this with completely stand-alone with headphones. This is not something unique to your unit. This is the way the Virus' sound engine acts in this case.

For a 1800 euros synth ?? it a total joke ............... IM A SO SO DISAPOINTED ! And i cant trust that .

Someone already answered me he cant reproduce the same problem . I need more feedbacks please !!!!

THANK YOU

BEN

Alors non ce n'est pas du spam ,, si j'ai refais un post c'est parce que je n'ai recu aucune reponse depuis 6 mois .... et que je GALERE GRAVE .....

bref : lien soundcloud :

pour le preset rien de plus simple :

sound init with smooth mode on

Only Osc1 alone with sawwave .

Transpose : 0

only filter 1 with high pass filter , filtercutoff 65

bend : +63

No effect , no lfo , juste une saw toute simple joué en note C3 et ensuite modulée avec le knob semitone de l'socillateur 1 , rien d'autre . Et il se produit la meme chose si je module le pitch du osc1 avec un lfo .

Sur l'extrait audio de soundcloud c'est super clair .....

sorry i foregt to answer you in english , i made an other post cause i didnt get any answer from nobody from 6 months ago and i need people to check with thier unit if they can reproduce the problem or not .

Only one people told me he couldnt reproduce the problem .

Access vanswered me again today after contacting them again , telling me they already answered me that they can reproduce the problem and that there is nothing else they can do . I dont trust that . I cant imagine a 1800 eur viurs ti2 not able to pitch any waveform ( cause this actualy happen with sine , saw , square and all other wavesform ) without producing heavy noises cracks pops and artefacts in the high frequencies . Thats totaly unrealistic .

If some other people tell me they can not reproduce the problem , then it mean access dont want to move a finger to help me to repair my unit ....

no need to upload the preset , its the most simple patch ever , any kind of wave with zero effect , lfo , noise , sub osc ,

just 1 oscillator with nothing else and then move the semitone knob , or use lfo to modulate the osc1 pitch , witch is the same thing .

Virus told me they could reproduce it with 2 different unit and for them its the way the virus engine work ........

Todays answer from Access after contacting them 6 month later for the same problem :

Dear Ben,

We wrote you that we were able to recreate the issue here. There's not really anything we can add to that.

So please , i realy need people to try this and tell me if they can reproduce the problem or not .

If people have the same behavior , i will just sell my virus and buy something else loosing 800 eur reselling it .

Because this problem , even if you listen clearly at it when you have a very simple patch , and it become unlistenable when you have a more complex patch , its obvious its still here and the audio quality goes fucked by this cracks noises and artefacts , thats ,not acceptable for any synth .

Doing the exact same thing with my nord lead 4 , i dont have any single pop or crack , sound stay totaly clean while using lfo or transposing the pitch with semitone knob
