In a UI Design discussion the Bluebox was cited as making good use if it’s 4 rotary encoders.
Just had to mention it here as it has a look of having Zynthian DNA. Priced as if it could be a cash cow, though I don’t know what the euro rack sales are like these days, wonder if a Zynthian case blank could be machined into a digital euro rack thing.
