Mod wheel makes parameter changes without touching it

[hvyen]

Dear friends,

Now I have my second TI2 Whiteout Edition Keyboard, because the first one had problems with the Mod Wheel. Last friday I changed my new Virus because of its error and I got a new one, but it has exactly the same problems. So I think it's a bug and not a mechanical problem, but I'm not sure. If all TI and TI2 Keyboard owners would check this, we can see it's a bug or not.
The problem is: The mod wheel makes parameter changes.
For example: Choose a sound which you can modify strongly with the mod wheel, that your hear the changing of the sound better. If you push the mod wheel down, the mod wheel doesn't affect the sound. If you push the wheel up, you can hear the modified sound (for example a vibrato of a bass sound). Now let the mod wheel in the upper position and choose another soundpatch with the value buttons and directly go back and choose the soundpatch which you had before again.
With this action you should have the sound which is not modified by the mod wheel (no vibrato) but the mod wheels position is up.
Now wait a few minutes (it could also happen in a few seconds) and the mod wheel will change the soundparameters to the value of the wheels position.
I hope that you understand what I'm trying to explain. Please try it out so that we can see you have the same problem or not.
My Virus is not controlled by other Midi-controllers!! Only a headphone is connected.
Thanks and greets,

Marcel
