Edit : There’s no way Arturia didn’t know this was incoming from back in April, here’s the original Behringer video the screenshot was grabbed from - they’d know this was a KS clone shown, so maybe that’s why they’ve changed the lineup with a 37, although it still doesn’t leave a lot of time to get the new model to market ?!
