Tomorrow I'll try it with another computer

How did that test go?

Curious I was sure I updated the thread with this information... Maybe I forgot to click on "submit post"...
Anyway, the test went negative... Same problem on my other computer....... But only with Z3ta... :(

All I can think of now is to take the engineering approach and get some actual data. We need to know what your controller is sending. I'd try either MIDI-OX or Mountain Utilities MIDI Tools and see if you can capture the data stream being sent from your controller when you operate the pitchbend wheel.

Hi, thanks, I installed miditool but I'm not sure to know what we need. I tested the input and it looks just fine...
What can I send you?
 
Ah, another thong, I contacted the customer service, they just told me to check if I had the latest version... I sent them a reély saying that I already had it..... Waiting for the next answer.... I'm a bit disappointed with this synth...

Okay so... For the fourth time I uninstalled and reinstalled Z3ta+2.
The result is that, after trying as a standalone, it keeps doing it. Good point is that I tried within Harrison Mixbus 32c(Not yet within cubase) and it works good....... That's strange... It was everywhere and now only as a stand alone...
 
At least, now, I can use it to play and record...
Maybe I should send another mail to Cakewalk to let them know.
 
Anyway, thanks a BIG lot for your help! It should be fine now!!
Cheers!
