Hi all, I just realized why my example code "didn't work." It was a simple stupid human error (surprise, surprise), the change did occur, it was just that the sinetone was 400Hz and I was altering it by 0-1 Hz with slider output which on my lousy laptop speakers in a noisy room seemingly did not make a bit of difference (at least not to my ears :-). Anyhow, thank you very much all for your help in this matter! Btw, Stefan, you mentioned that there were some updates to SCUM. Are these included in the latest 0.0.2a version? Also is this the same version like the one presented at LAC last year? Many thanks! Best wishes, Ico
