Maybe they found a bug or two in the last minute and wanted to fix the OS first. However, I assume that this release doesn't offer too much news and is rather developed for the upcoming keyboard version.
However, Arturia US pretty much told us about it in the first place, so it cannot be that bad. Still not sure why the settings are split up in two sections. Maybe we get some more stuff in the future. Also, I noticed that you can start the sequencer with audio in. Never used it before, but I never saw it before either.
OK, since Arturia seems to work still on the OS you might want to take a look at the origin oscillator. When I choose Oscillator 1 and 2 origin, I go on oscillator1 and have oscillator 2 open in edit, I can see the blend out of the PWM section with changing oscillator 1 waveform. Works the other way around too. Nothing major but nevertheless, worth mentioning.
