Hi Roel,
What you've already said about the SB, is true (except for the "amplify" part).
The lower pot (-/+) attenuates the In signal, and/or inverts it, in a gradual way.
Turning that pot fully CW or CCW does *not* add gain; it merely passes the incoming signal completely.
The upper pot (-5/+5) simply *adds* a positive or negative steady DC voltage to what is fed into the [attenuated] Input . So it "scales" the input either up or down (het werkwoord 'scalen' betekent o.a. omhoog- of omlaag gaan; bvbd. 'scaling a wall' betekent 'op een muur klimmen').
Used on its own -- that is, without any signal fed to the Input -- it just puts out that steady DC voltage. In that sense, it is indeed a CV source; only, it's a *steady* and manually-controlled CV source. There's no LFO or something hidden underneath it...
And that's it.
Just a simple utility module, but nonetheless a powerful one.
The most common use of the SB, is when you need to attenuate (or 'attenuvert', as it is sometimes called nowadays) a signal fed to an input which has no attenuator pot (which happens frequently on Serge modules).
I sometimes use the -5/+5 pot simply to tune oscillators, by setting it to exact voltages (1V, 2V...), but of course the combination with the processing attenuator makes it seriously more funky.
I use the Scaling Buffers in almost every patch.
Hope that helps,
