So far mine seems pretty stable although I am not interested in DAW integration, so I can’t comment on any issues WRT. I had a couple of crashes, ome when doing a transfer, and one when trying to select all then copy samples, the transfer app also seems to be a bit picky as to whether it will recognise the DT on my computer.
Win7, the device manager sees the DT fine, as does C6 but the transfer app does not always, resulting in a few swearing, unpligging and rebooting cycles.
I’m not 100% convinced of some of the UI choices, sure these are down to personal preference, but so far it seems too easy to accidentally change sample, navigation is sometimes a little inconsistent, and some of the graphics could do with a tweak. The audio editor is ok, the loop scheme is a bit weird, the browser is similar to (analog) Elektron machines so if you are a fan of that (I’m not, I prefer the OT browser) you will probably like it.
Overall though all things considered its not a bad little machine, nowhere near the Octatrack but that is no bad thing in my book., I like them both for different things.
