I use Enttecs with Pixeldrive a lot. My overall impression is not very good, but most probably it's the Pixeldrive to blame, not the Enttecs. Personally I am quite happy with them. When I use them with pixeldrive I can drive 8 DMX lines, with Pixelmad or Catalyst - only 4. Is it possible to change this?? For quite a time I have had the intention of buying Pixelmad or more lines for Catalyst (upg), but this is the reason I didn't yet.
