Hello,
There's something I don't understand.
This works very well :
suiveur_parametre = _ : an.amp_follower(0.01): si.smoo ;
freq == 180 + suiveur_parametre*400;
process = os.osc(freq) ;
When I insert in the STinkle example of the Biblio, instead of the "freq"
controlled by a slider, I get an "connection" error message [...]
"The number of outputs 1 of the first expression should be greater or equal
to the number of inputs 2 of the second expression"
I copy the whole code, if you want to try it. The problem is written *in
bold.*
Thanks a lot. Maybe it's something of the "Faust philosophy" that I don't
understand, so it " blocks" me for further coding ...
