Well, it's not that huge of a deal
but it's just a lack of consistency in the interface. I only have 4 of the synths and each is different:
1.Arp2600v - Click on the Arturia wave logo on the right of the keyboard for version, Arp logo does nothing, setting button on top of synth interface, no Mac menu items at all.
2. Minimoog Original -(free) - Click on Arturia name plate on top left of keyboard for version, Moog Logo does nothing, setting button on top on top of synth interface, no Mac menu items at all.
3. Oberheim SEM - Click on Oberheim logo to right of keyboard for version, Arturia logo does nothing, no settings button, Mac menu for preferences and for version under Oberheim menu header.
4. Analog Factory - Arturia logo does nothing, no settings button, synth logos do nothing, under File menu are Audio and Midi preferences and the version number is under the Options menu item.
So that's what I mean about the GUI....
