Here's an update:
After checking the parameters for the factory patches, I noticed they were not correct. So I manually entered in patch 11 and low and behold it made sound (it was a string patch). However it was still wobbly - like the joystick was engaged up or down - but it was not.
Also, after pressing the Write button and going to patch 12 and then back, everything I entered was gone (i.e. leads me to think the memory is not working).
