I bought a box with version 1, which does not offer the AU format (but nine 120 euros, hiha !!) ... MAS format is apparently DP3 (according to the table at the back of the package), and ... I work with DP4, suddenly, I was scared! but no, arturia of people put all this in a day v2, tlchargeable gratos on their site (21megas mac).
suddenly, the CD, double click on the wise v2 and AC drives, the standalone and AU are yours!
The manual, in French, is very good with the basics of subtractive synthesis, tutorial, basic, etc ... c cooool!

ADQUATION / PERFORMANCE

I have a dual 2GHz G5, 2gig RAM, a 828 mk2, ca superbly running standalone, a little harder in a big session with DP4 to 5 (rev, delay ...) 12 compress a plug, 6 ou7 filters :dropoff window
it will run but the display ram a bit, the MMV food quite proc resources, buffers may be to increase, depends on the latency, but hey I'm a bit pushed for even mm ...dropoff window
Standalone when changing patch, see to it that it is well loaded before sending a note: if one makes too fast ca plop in pregnant because all the wiring does not appear instantly.

NOTICE GLOBAL

I use it for one week and barely basic dj, Keske j'mammuse!
presets are not all to remember and you often remove the delay and chorus utiliss abused to discover big wicked sounds ... I spent a good 3 hours just to tweak my ammuser presets, sound is large, the grain is resonnances..aaaaahhh..c'est typ ... filters and it's good!
3 * 3 Osc, LFO to move filters, envelopes, etc., a squenceur analog, infinite modularity, I feel that the only limit of this synth ... that's me!
