ADDAC401

With the ADDAC401 Envelope Follower you'll be able to use the volume of any sound source to control your synthesis.

Our envelope follower has an interesting twist: besides outputting the volume information through a regular CV output, it also sports 8 independent gate outputs, triggered by the corresponding levels of the VU meter.

You can also control the offset on the gated outputs, either by CV or by steps through a special dedicated gate input.

Input Level and Decay controls allow you to achieve good envelope follower amplitude reaction.
Envelope Gain and Offset allows to set the envelope CV output to any desired CV range.

Monitor Leds for both the CV output and for the digital detection circuit.

Note: All specifications and features are subject to change without previous notice.

In case you're wondering: Sure! We can get you a custom coloured front panel for the ADDAC401.
It has an additional cost and takes 4 to 6 weeks to be ready.

At the moment the ADDAC401 standard panel colour is Red.

A custom colour panel can be done in either Black, Green, Blue, White, Silver Gray, Yellowed Silver, and Dark or Light Bronze.

Print colour varies between Black, White, or Red, Blue and Green. We recommend lighter-tone print for darker panels, and vice-versa.

Please note: we don’t stock custom coloured panels. For every custom order we need to make a single panel order from our panel provider. This explains the panel price and lead time.

Thanks for your interest in the ADDAC401!
