hi, carl !

first, thank you very very much for your kind help. all of your 
suggestions are interesting to study and all have a distinct modulation 
"flavour". i have to confess that i don't fully understand the [bob~] 
approach, but the rectifying example was very clear.

after a little tweaking i came to a solution that sounded the closest to 
the effect i was looking for. the difference in my approach is to clip 
the frequency input of the modulated osc not at 0 Hz but at the carrier 
frequency.

example attached

thanks again for your examples !

best
