On Eclipsed Sounds'
blog post for Saros, they also mention some other interesting things:
This set of vocals is called the Starry Court series
They're planning one more voice in this set, and then they'll switch to a 'very different (and highly anticipated)' direction. I have no idea what this could mean. It feels too dramatic to just be a theme change. The fact they're working more closely with Dreamtonics on SynthV's development opens up a lot of possibilities. Mind: boggled.
Oh yes: big congrats to the team for being able to go full-time. This is a significant milestone that suggests the Starry Court has been very successful!
I'm sure it's a dream job for long-time vocal synth fans.
