EFG

Envelope Follower, Gate Extractor and Pre-Amp

The Oakley EFG has a fully variable speed CV output that can be set to respond both very quickly and more slowly to incoming audio. The module also provides a gate extractor. This part analyses the peaks in the music and creates a gate type signal in time with these peaks. It can be used to trigger envelope generators in time with an external drum loop or click track. Two rotary controls, threshold and response, enable you to get clean gate signals from all sorts of input material. In addition the module includes a wide range three stage input pre-amplifier. This enables the user to hook up guitars and other unbalanced external instruments to the module. The pre-amp output can be used for driving other modules.
