For those who might own a MacBeth Micromac-D, the elusive spec for the MSRK module designed by Kenton has just been published here:

This is not a Kenton supported module in the Mac, but they’ve been kind enough to provide this by popular demand.
Details include Midi setup, functions and a mod for midi control over VCF.
Aye!
