Hi there - I'm wracking my brain trying to figure out how to make a sawtooth XLFO in Volcano (or any of the plugins).
I can create a linear (or sine) climb in step one, but I can't seem to delete step 2 without removing the ascent in step on. If I leave Step 2 in flat, I can get something that goes up, but it pauses while on step 2.

Basically, I want a simple LFO that starts low, ascends to a high and then repeats (jumping back to the bottom once the top is reached). Or, in other words, a Sawtooth.

I'm sure I'm doing something incorrectly here so I'd be grateful for any advice!

Thanks!
