I'm usually one of those people that either like to sequence in the host piano roll or use interseting arps within a synth so I wasn't that interested when I first saw this, but after looking a little closer at the functions and reading the write-up, man it looks like a lot of fun!
I'm sure this is all doable with Max4Live, but it does look they made a pretty impressive little sequencer there eh? I think it would tough to replicate the gui experience and all functions with a Max4Live patch.
... and to think I was supposed to be beta testing for these guys, but I got too busy and forgot to send back the contract.
