imo, the rudeness and hostility in the customer service arena are worth not using one. forget about support... don't think about asking about enhancements you might want to make to your unit (even a LED color change, anathema!)... and NEVER email directly and ask about mac support.
too much ire.
this was only my personal experience. feels like buying a product and having someone pissed off you're using it.
on the other hand. nice and compact. but the stuff Jellica mentions is true... i've not had much success using it with goattracker either. dropped notes, just some general weirdness.
i think overall if there were more support for the line (both from the people who make them, mac stuff.... even VST development) it would be a better product. i just never got beyond this, and found myself with too much frustration, which after trying to seek help from them was just compounded in some big ways. seriously.... who answers an email about virtual machines and VSTs with a threat that if i use the device in the way i've explained (in a virtual machine) i'm voiding the warranty (period. end of email.).
