afraid alesis is not known for shareing their schemos... had to work on one of those back aways and was flying blind as you are... good news though... you may not need it since its only one module... the key is to compare it to the modules next to it... find whats changed and fix it...

From what I remember about the X2 when I was in charge of them at Alesis was they were prone to pwr supply issues. It's been 12yrs so I don't remember particulars but there's probably some zener diodes on the group that are fried. From there track forward. Are there any scorch marks? Burnt components? Doubt it's a deal breaker, any qualified tech could fix it.

They had current limiting resistors that burned open when something was shorted. Look for those on the bottom edge of the PCB. those were 10 ohm. It means that something is shorted on the board if those are burned.
