Issues with Pulse Train, Saw

Hi all. I’ve been working on a patch using amplitude modulation synthesis, and I keep getting this aliasing/popping. What I tracked it down to was the saw and pulse train objects I had been using in the synth. When I hooked an oscilloscope up to the objects I noticed that there was a small jump in the wave form, corresponding to the clicking I was hearing.

Has anyone had this issue? It seems to happen in both objects even when they’re I created a new object and give it values. This seems like something so fundamental that I’m probably missing something obvious, but I have spent a lot of time trying to figure this out, and I couldn’t find a previous thread relating to this. Thanks,

if you use train~ in an oscillator patch you should upsample the
whole thing for at least 4, better 16.

I’m sorry I’m not familiar with upsampling.I’ll look into it.
