Thanks Ken but maybe I wasn't clear enough in my post, so let me reformulate :
- the clock IN is slow
- the CV IN's are slow
- the CV OUT's are varying slowly indeed, and at a rate depending on the clock rate, so no problem there
- but it's the internal rate of these CV OUT's that's fast (all 4 of them), and make them more sound like oscillators (indeed slowly varying ones) instead of slow CV sources
