AJ:

I sent you couple emails, no answer, let's try here.
My friend Dennis Murphy sent you several months ago one of his SD1s, it was in great shape, ever since the EXP "works" erratic...midi files stop in random places, it does not follow a pattern. In style playing mode, also "works" questionable....it adds out of key notes...
Please help, I know you are a busy person, and so am I, I appreciate very much you reply, I feel responsable because I told Dennis about the EXP, and he only wants to get it back to Factory default.
