Unfortunately the Matrix-6 does not allow to send the modulation matrix parameters as individual parameter changes. You can only set these as part of a complete patch dump. In other words for every change in mod matrix settings you need to send the matrix a full single patch dump. It works well, albeit a bit clumsy. I have used this method to build a combined Matrix6/Matrix1000 editor / librarian in the past for Atari ST.
I am not sure how well this would work in a Logic enviornemnt though...
Cheers,
