I've encoded the result of my analysis on a new VSTi/AU plugin, which can be used to play sounds from all SA-based Roland product, like the MKS-20, the RD-200, the P-330 and the Rhodes MK-80.

The analog parts, like the chorus and phaser, are still to be done, but they can easily be replaced with existing effect plugins.
