I really really like it, but then again I was raised on RM1X and QY-70. This is the mothership compared to them. I mostly aspire to do some kind of indie pop/chillwave/folktronica type of stuff and I find the 64 step limit of Elektron sequencers somewhat limiting. I love parameter locks as much as the next elektronaut but writing longer tracks and different parts with the QY is a lot more enjoyable. I’ll never feel the need to complain about Digitone/takt missing song mode because I have the mother of all songmodes on the QY.
There’s also a lot of groove tools which make nondestructive and very cool rhytmic tricks on your sequences and then there’s some Kordbot -type of tools for transposing and stuff.
For me the QY-700 is a bit like a musical typewriter. I get a song idea, I write it down. It’s like second nature. This is the closest you can get to complete independence from DAWs. You get a piano roll and a lot of other DAW-like features without ever having to touch your computer.
