a multimode filter 100m?

there is a site on the web showing this module 121 mod for the 100m system (roland) ..m121_mod.jpg (JPEG Image, 356×541 pixels)

I’d really like to know, who „synth ollie is“..
anyone on this one?..
there are even cool pics on that site.. maybe it will disappear some day.. a very nice system 100m shot (12 cabinets)..

inspired by matrixsynth..

synth ollie found: thanks for info.. so it is in fact more a changed than a modded 100m module since it contains a SEM pcb instead of the roland filter pcb.. thats the secret..
thanks for the info, ollie!
