There is considerable discussion about the Skulpt on the most recent Sonic Talk 540. It starts at 10 minutes in and goes past 24 minutes. Of course Nick has direct knowledge, he had used and featured the Skulpt recently. But more significantly Matthew Hodson, was a guest on the show, and he is developing a piece of music on the Skulpt that is likely to be featured on Modal’s Kickstarter page and he has been using the Skulpt for a considerable length of time. Hodson, who has a lot of electronic music experience, had a lot to say about the Skulpt and is very positive about it. He is using it under Max-for-Live for instance. Sounds like Hodson plans on making it one of his synths when it is released and he certainly has plenty of choice.
There is info also in the video about the 8 oscillators per voice, i am still trying to figure out exactly what that means precisely – it sounds to me that separate oscillators is literally what it is, that it comes down to the sort of separate control you have on all those oscillators.
To me the Skulpt is starting to sound like a no-brainer, as a purchase, though there is a ways to go yet.
