Todays answer from Access after contacting them 6 month later for the same problem :
We wrote you that we were able to recreate the issue here. There's not really anything we can add to that.
With best regards,
Access Music Support
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
