You don't need a trigger to use the Smooth section of SSG for glide.
Just patch any old thing In, and use the Smooth Out to drive something
else, like an oscillator.

Yes, you can use the SSG Stepped for sample-and-hold fun, if that 's
what you're looking to do. Trigger it with the Smooth square LFO
(autoerotic sample & hold). Patch a repeating lfo from a DTG or other
module into Stepped In, and use Stepped Out to drive an oscillator. Make
sure its Rate is fully clockwise, at least to start with.

Happy Patching!
