I'm personally very happy about the volume increase! I also like the other improvements so far.
Other than that, it's a bit of an underwhelming 2.0 update.
I'll put this in a bug report as well, but I want to mention it here, and see if others notice this too:
1. As in V1, you sometimes hear little clicks when you play legato lines on certain patches.
2. In V1, it was possible to shift-click on a knob or fader to fine-tune its value. This doesn't seem to work anymore in the new V2. Please bring that back, dear Arturia people!
3. I like my synths raw, so I always turn off the FX. As in V1, the FX section is still too many mouse-clicks away to be able to do that conveniently. Please think about putting some kind of "Patch-FX On/Off" switch, or better, simply the FX controls, on the main surface. But, at least an FX On/Off switch.
4. I'm not at all a fan of the GUI getting bigger when trying to access the extra features. Maybe it's possible to open that extra window where the keyboard graphics is? There's no unnecessary animation and it goes quicker.
