Dear all,

  Anyone seen this?

  Look just below the "red square" synth, It claims to be an analogue patch
matrix.
Having looked at this myself several times Im intrigued to know which matrix
chip has been used.
Remember the discussions about Ron and such for the matrix 'switchs', most
of these are 100ohms or less (more commonly 50ohms) and might present
problems when trying to sum several CVs to one output, so did this guy crack
it?
