Hi Todd,
thanks for the kind words about the Zaquencer! I´m happy that you like it!
Yes, the Wave Generator would be the tool for what you ask. It is a bit difficult for me to pinpoint the parameters exactly, and I would recommend just trying it out a lot to get a feeling for how it behaves. For your application I would recommend using the “saw” waveform though. The triangle goes up and down again. As a starting point you could try saw with Gain 100, Offset 0 and rate 2.
Actually now that I think about it more, your version should work as well. If you choose triangle with rate 1 you would only get the first half of the waveform which should do the same thing.
Cheers!
