Thank you so much for helping me so quickly!
It works great now, I attach the new file so if anyone wants to use it it is available.
I am new to puredata, just started very recently and still learning how the language works.
I created a minimoog style oscillator where I can change certain parameters like: waveform, fine tuning, panning, volume. This file I named oscillator.pd, after which I created a "synth.pd" file that basically uses two "oscillator.pd" as an abstraction.
The problem is the following: when I modify one oscillator it also modifies the other, so I can't use them separately but it's as if they are linked together.
I attach the files, thanks in advance for the help!
