The 230e envelope follower's transient pulse mode generates triggers only when a CV increase occurs — useful for extracting rhythmic info from complex audio

The 230e Triple Envelope Tracker has two pulse output behaviors selectable per channel. In normal mode (transient LED off), a pulse fires whenever the envelope CV exceeds the 5V sustain threshold. In transient mode (transient LED on), pulses fire only when the input CV shows a significant increase — regardless of the absolute level. This second mode is specifically suited to extracting rhythmic triggers from polyphonic or continuously active audio sources (like a drum mix), where simply thresholding on level would generate false triggers from sustained energy. The envelope follower also has variable decay time (0.1–10 seconds).

Examples

Patch a drum overhead microphone through the 230e in transient mode; route the pulse output to a 252e ring to trigger a sequence — drum attacks drive the sequencer without being confused by sustained cymbal decay.
