Expert Sleeper's Amelia is an envelope/function generator with an unusual ADBR (attack/decay/break/release) configuration.

CV control of all envelope times and of the break level is provided. The envelope can be set to auto-trigger, turning it into a complex voltage-controlled LFO.

The shape of the attack and decay/release sections can be independently and continuously adjusted from exponential, through linear, to logarithmic.

Amelia was developed with use with sequencers particularly in mind, where often you only have a trigger output, not a gate of adjustable length. It allows you to create complex, fexible, and modulate-able envelope shapes from that simple trigger signal.

The module is constructed entirely from analogue parts and discrete logic. There is no microcontroller or digital-to-analogue conversion involved (and so no quantization of voltage levels or of response time).
