Hi Florian, thans for these infos. Sinewave are always very important 
in my moduar-patches. All these sine-waves found on modulars sound 
way different. The 110 isn't clean at all, but has balls, where the 
111 has a much cleaner sine-waveform, but hasn't balls. I really like 
the Sine produced from a Blacet Final-Filter in Selfoscillation, but 
it doesn't track well. The Wiard VCO's sine is completely different 
than all the others. Rather clean (but) very nice. Two of these in 
lin FM gives some very warm and clean FM-patches. I talked to Jürg 
Oldani recently and he told me that the sine-waveforms in his huge 
Selector-OSO-Module are a very special and complicated design, much 
more advanced than in his (nice!) VCO. I really can't wait to hear 
it. (btw: did you ever test the selector in Keys?).

That sounds I as am a complete hardware-whore (which is true). But I 
make music with these things all the time, so it is no detail for me.
