I like Elektron devices and I own a Digitakt and Model:Cycles but I find this one a bit underwhelming, especially it’s lack of proper polyphony.
AFAIK, you can achieve polyphony the same way you can achieve it on the rest of Elektron machines, by manually doing it with multiple machines. I agree it'd be nice to have it out-of-the-box, but personally it's good enough for me.
