Hey there @Van_yan
ANA 1.5 is a now discontinued product from Sonic Academy and therefore it's not available for sale, nor for demoing. Though it was still a "maintained" until recently, it's also not compatible anymore with the latest MacOS and unfortunately, chances are that this is not gonna be fixed evn if the product is still supported so far.
Do check & demo ANA 2, it's much more powerful than the other version and provides so many more features and enhancements like the GUI. You can download a 14 day free trial demo version form the product page and it's still on a massive 65% OFF Sale since lockdown, so that' your chance to grab this synth at the lowest price ever.
Hope this helps
