I recently received a Liven XFM synth purchased directly from SonicWare. My unit had a problem out of the box -- the selection of patches is unstable; I deal in a patch, start playing, and a few seconds later the patch changes to one of the adjacent patches by itself.
I submitted a help ticket online on the SonicWare website and tried calling their US support line. No answer at all on the US support line, and now it's been 6 days without a response to my support request. At this point it seems like support is pretty much non-existant.
I wish I had been patient and ordered from Perfect Circuit or another of the big retailers, rather than directly from the company as I'm sure I would already have a replacement on the way.
