DESCRIPTION:
This video shows how you can generate a sub oscillator from the slope generator. Simply trigger the slope from the main oscillator's square wave and route the slop output at the input from the balance section.

The video shows first the oscillator's main triangle, then I plug the slope output and play with the slope rise time. You can notice the oscillator pitching way down from the original timbre.

Further play things to do is to mix this with the result of the overtone's generator, play with the rise and fall times and engage cycle for some crazy timbre.
