I'm looking at SQ80 or SQ2. Both are selling at $700 Australian. Are there any known problems with these? Whare can I find specs on these, I went to ensoniq.com, but they only had specs on new models. I want it for controling VST on my PC, but also want it to be capable of odd, fat, different sounds. Is it possible to load complete new sounds on to the machine? or do you just edit the parameters of the original sounds. Thanks
