The complaints that you get one unusable sound (kind of a fart sound) doesn't seem legitimate to me

The synth sounds really lacked the synthy type action I had hope

I had played with it for 2-5 hours attempting to get really great sounds out of it, and it seemed almost impossible

it can be tricky to get the right sound, and there's a million ways of getting the wrong one

The sound can be altered so drastically with only one change, this can make getting the perfect sound a bit complicated.
