The Abstract Data ADE-51 is a little more than your average Envelope Generator Module, aside from standard ADSR duties it includes a fifth stage in its envelope response, making it an AHDSR envelope for more complex and expressive envelope results.

The ADE51 also includes full CV control over all of the envelope controls, which can add some serious expressiveness, dynamics and randomness to your sound. There's also exponential and linear responses for super tight 1ms envelopes and in longer modes, a maximum of 10 Seconds for the A, D and R stages and a 2.5 Second maximum for the H stage.

And that's not all, there's also two outputs, with the second offering and inverted copy of the first without the need for attenuating or re-biasing your CV.

An incredibly useful modulation tool, with plenty of features. The ADE-51 is a great EG for any modular user.

The main features of the Abstract Data ADE-51 Envelope Generator Include

• AHDSR envelope
• Linear and exponential curves
• Two output with one inverted envelope output
• Full CV control over the entire envelope generator
• 10HP wide
