Exactly. I did not say it’s impossible, but as right now the sliders get built in a simple manner, constructively in a loop counting the samples from 1 to #renoise.song().selected_instrument.samples, I’m not sure is as easy to also make ObservableNumbers in the same loop. I already have a request posted about this (I mean come on, making an ObservableNumber document in the script just to bind the slider to the actual ‘Observable’, … too much for a week day, give me a break ;D)
Ehhm there might be something similar in Overtune dialog indeed… if that works it might be easier than I expected at first, thanks for the idea
