I recently got my Base replaced (it had pads not working properly), via the thomann warranty. long (one month) but free shipping.
and the replacement Base also has a problem : at some point the 5th fader gets stuck at 0 and won't move up anymore (it can go up to around 35 max but then it jumps back to 0 as soon as I remove my finger). usually takes some minutes to get in the stuck position.
only way to get rid of it is to unplug and plug again the Base.
I got this bug at my first gig with the brand new replacement Base. and at every gig afterwards.
at first I thought it was an error in my puredata patch.
but then i had the same exact problem in a 100% different condition : different computer, different OS, and with a totally different puredata patch. anyway if I close puredata the bug stays. and even if I restart my computer without unplugging the Base.
the problem doesn't seem to occur when I leave the Base idle. only happens when I use it. although it doesn't seem to be related to the fader itself.
I actually do almost not use this fader with my current performance config. however I'm currently working on a new config that uses every control on the Base and having a non-working fader isn't an option.
here is a video of the problem : https://www.mediafire.com/?o4oqqfkvgojtp6x
I guess this qualifies for another replacement. although I have gigs comming and can't wait another month to get the Base back.
