Not what he plays but what he says...
I'm not amazed by the sounds he's getting out of this instrument but I agree with most of the words he is saying.
For me, it was the amazing sounds that got me into synthesisers back in the late 1970s. But he's right about the 'note on - note off' nature of keyboard instruments.
They are not organic instruments like a 'box with strings' or a 'bigger box with fatter and longer strings' or a 'tube that you breathe into' or even a 'tub with a skin'.
88 buttons in my favourite colour scheme, that's all they are. Could they be so much more?
If so, then this isn't it. It looks and sounds awkward in every video I've looked at.
