Hmm... now here's a lot of options! Anyway, I want sounds to evolve in both
directions, for example a filter to open and close again. What I'm after is
something that, if we stick to the filter, at random times opens or closes
(randomized) the filter with random amount... The 149-1 seems, as you said,
very conrollable with its cv inputs! But do I actually need negative voltage
to close the filter, or just less amount of positive voltage. Sorry about
these very basic questions, this is one of the things you really don't have
to make a big thing of when hazzling around with my nord modular, you pick a
module, you pick another one and off you go! Not quite the real thing ;-)

Btw I missed on the 149-1 needs to be triggered, my mistake! But I'll
probably put in an LFO in my system anyway, and I have S&H out from my
system 100 which should do the trick you were refering to Ingo, though it
might not be that slow come to think of it... ah merde, need to read more!!
