Yamaha SEQTRAK Black

I don't understand why they would make something that's supposed to be portable so flimsy. Judging by weight it seems like there's more plastic in the packaging than the actual device. The keys all work fine but are obviously the mushy membrane kind, and the tolerances aren't too great which makes them a bit wobbly. They are obviously meant to be pressed in the middle so the whole #keygate thing seems overblown to me. The base plate is slightly misaligned in the middle below the synth section, as mentioned in one of the other reviews. Other than that, everything works as it should, and it isn't too difficult to use. No issues with app integration either. Sadly, I need something I can (confidently) take outside with me (which is basically the only reason I'd get a device like this) and I'm not confident that it would last very long if I had it in my backpack every day. I'd say get it if you're careful with your stuff, and don't plan to carry it with you very often.

From the get go sound selection wasn't too fluent for me. I found that navigation through the library was tedious and time-consuming, getting the effects just right wasn't too straight-forward either without using the accompanying app. On the plus side, there are a lot of sounds and effects in the standard repertoire. It felt like the timing of the device was off very slightly every once in a while (without having randomness or micro-timing enabled). The speaker is bad and doesn't do the sound library any justice, so you have to plug in a monitor of some sort (I mainly used studio headphones). Build quality wasn't what I expected at all, it felt like wobbly plastic. There were two panels at the bottom that didn't line up nicely and every once in a while when I picked it up, they shoved into place. The keys were wobbly and tactical feedback wasn't too good. All in all, there is potential if they improve the build quality and navigability of the device.

Unfortunately i found this to be too much of a toy to incorporate it into more serious flows or projects. The lack of a screen becomes annoying after a while. Sure, the app it comes with supplements that, but its midi editor is fiddly and impractical on a tablet.
Back to the toy itself: build is flimsy, for example the side buttons sit at different levels and they certainly are not intended to; the synth keyboard very limited in ability. Working with pages hinders the flow.
On the plus side, the sound and sounds are nice.
I would suggest to anyone who's serious about music making to save up and buy a digitakt.
