I have the base 1 for almost a year.
I started to use it around march, only for gigs. (approx. twice a month)
I did notice some pads were a bit harder than others, but nothing alarming.
but it's getting worse and worse with time.
the 4 right pads are below the plastic casing and are extremelu unresponsive.
some pads in the middle aren't very responsive too.
oftenly pressing a pad counts twice. it happens a lot when I press several pads at once (almost all the time).
I tested with the online editor I can observe this in the midi message monitor. (I use fixed velocities).
does that justify to send it back ? (I bought it @ thomann.de) because technically everything works. it doesn't work perfectly but nothing's broken.
thanks in advance
