I have had two SD2,one SD4,and one SD40,as well as my Audya76. My Sd2 is still great for my sequencer software on the laptop,where I don't have to do anything else. The SD4 was fine,but I bought it to run leads,also,but found it a bit quirky(probably me). I chose the SD40 because of it's smaller size,but having everything I need.

In spite of Italy,Frank and AJ have always been right there for me,thou I have had no real problems with any Ketron.
