> I thought one needed a A-185-1 for every two oscillators because on the Doepfer site it says "In general the A-185 is recommended as soon as more than 2 VCO's (A-110, A-111) are controlled by the same control voltage source." But I must have misunderstand that remark. So I save €50.

Ah, I see the confusion here. I *believe* that without an A-185-1, the output directly from the MIDI to CV converter is only strong enough to power two oscillators, but *with* an A-185-1, once the signal's gone through it, it can power a practically unlimited amount, like a whole row of just oscillators, even. I gather this is what the whole "buffered" part means, that it boosts the signal in some way.
