good news about the mods from Bakis.

2003-03-31 by Andreas Lindholm

Very nice news indeed. Not that I would dare to mess around with a solder
that much myself, but I think a wast number of mods like suggested here
would indeed give Doepfer as a brand great goodwill. Personally I wonder if
if would be possible to add modified versions to the choice that is up for
sale. I mean if we can have with blue leds why not also have these mods up
for a small fee. (audio enabled a129/3 extra xx bucks). ?
