Oh, you mean the 99 euros includes Phase Plant as well as their MPE expressive suite. Hmm. I'm seeing it for $99 USD (accessing the site from the US). Looks like it ends April 15th.
Wonder how many of the expressive suite presets use effects other than the free ones... so that if we want to edit those effects in the presets we'll have to pay extra for each effect. In the preset playthrough I can't really tell, though I definitely see multiple simultaneous instances of Convolver in the walkthrough video. I'd assume that there's no way to demo the expressive suite before buying. Bit odd that they came out with this offer so soon after Arturia did something similar for Pigments (which did get me to buy Pigments...).
