Greg,

speaking of stuck notes, I got this twice already. They were on the higher octaves.

The way I got out of it is:

1) rebooting

2) pressing the STOP button twice [style STOP button not the song STOP one]

That already worries me.

I recently installed the 8MB of backed DRAM. the default 2MEG is not good enough.

My keyboard is the powerstation one; I also installed the vocal harmony expansion. However, by doing that, you cannot expand the memory of the keyboard because memory slots can either be used for vocal processor or memory simms but not both.
