Thanks a lot for tips troux.
5) Add an Ochd
I've considered a lot ochd, it's great to have 8 lfo on 4 hp, but I always wonder how useful could be it, considering all lfo are unsynced and it isn't capable to sync with a external clock, or maybe I miss something? Anyway I guess it was always in scope, just I've hope to find something more handy.
4) Add a Kinks
Yeah, you make me to validate :).
3) Add a Doepfer A-118-2 for your Clouds (and for #2, keep in mind that this needs a square cutoff to trigger)
Interesting... but adding this is worth it , considering you could generate differents waves on PNW (including random)?
2) Add either a Batumi or a Zadar, depending on your end priority here of modulation (Batumi) or expression (Zadar)
I think my priority is expression, but I'm afraid I haven't got enough modulation... maybe if I add an Ochd I'll get enough?
1) Upgrade the Function to a Maths
I'm not sure with this, function it's enough complex for me to keep it a while, upgrade to maths make me a bit scare. Sure maybe in a future when I feel more comfortable. For now, I try to learn and discover.
