Hi and welcome to Arturia forums.
Thanks ! I'm new to keyboards, and even more so to synths, so please bear with me.
What wah-wah?
Like a pulsation, one cycle per second, or like a very slow vibrato.
Is it by any chance the Vibrato and Tremolo effect you get, if you use your modwheel? If your modwheel is set to zero, then you should not hear this.
Mod wheel set to zero.
The Vibrato and Tremolo section you find in the Extended view. (The button with 2 arrows in the applications toppanel to the right.)
Not sure where this is. With "extended view", do you mean the panel that opens when clicking on the wooden top of the instrument ?
Using a Keylab Essential, there is a Vibrato rotating button, but it bears no effect, regardless if it's set to min or to max.
Just in case: Also there are a Chorus on FX1. Turn down the FX1 knob to not hear this.
The effect section you also find in the Extended view.
The rotating button FX1 is also set to min.
EDIT: I forgot to mention, that the MOD AMT knob on the front also need to be turned fully right on the Solina V2 in case you have edited it. EDIT END
Yes, it's turned fully right. And based on the Arturia Software Center, it's indeed v2 that I got with the V Collection 7. The preset is called "Diamond strings", but I do get this pulsation or wah-wah on any Solina sound.
