Im new to PS, and I am trying to get started with "Programming Electronic Music in Pd" by Johannes Kreidler. In the first example, when I add the number box and then switch into "execute mode" and use the mouse to change the numbers, the sound suddenly cuts out. It doesn't come back until I make a change the the frequency of the oscillator. Is this a bug, or am I doing something wrong?

Nevermind, I just figured it out. I had the volume turned down low and I just wasn't hearing the low frequency signal. It seems to be working fine.
