@Ale-H.H. That is strange....... I cannot think of a good reason for it. There is a click as well, and its as though the osc frequency message has gone instantly to 0 (zero)...... so a fundamental of 8 Hz.
I might be wrong....... there might still be sound there but my crappy mac laptop speakers will not produce it. It could be an overload at very low frequencies.
What does the audio look like in an editor?
Do you see one of the two faders on the module doing something you don't expect?

It sounds really great apart from that!

@whale-av yeah, the frequencies start jumping, other than that it might be my soundcard and I might need a new computer lol, ill try and see if my buddy can reproduce this without any problems,

@whale-av my computer was just exhausted, that is why it stopped again and again,,, now for the unwanted sounds at the beginning i dont know, it happens when the timbre of the curve isnt a sine wave and its all the way at the top at 12543 hz
