Expert Sleepers released Amelia

Expert Sleepers released Amelia, 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 and flexible envelope shapes from that simple trigger signal that can be fully modulated under voltage control.

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