Patching SSG Smooth output to its own VC Rate input creates exponential glide on sequencer pitch

The SSG’s Smooth section provides linear pitch glide between sequencer steps when patched in series. To change this to exponential glide (fast attack, slow release — or vice versa), run a short patch cord from the Smooth output back to the VC Rate jack. The output voltage controls the rate of change of itself, accelerating the glide toward the target. This feedback patch is a compact alternative to external function generators for expressive portamento on a Serge system.

Examples

Sequencer CV → SSG Smooth IN → oscillator V/Oct. Then: SSG Smooth OUT → SSG VC Rate. This creates glide that rushes to the target pitch and slows near it.

Assessment

Compare linear vs exponential glide on a Serge sequencer patch. What single connection converts linear SSG glide to exponential, and why does it work?
