hello all
i have just received my quasimidi raven
it is fitted with the raven max expansion
but it seems not to works fine, i thinks that the problem is the expansion

so i need to replace the expansion componnent by the original quasimidi raven
there is 3 eprom and 1 chip

if you have any idea ...
