HM2017mk2 - Dual Envelope & VCA

Dual AD envelope and VCA. Features VCA cross-modulation, signal mixer, and many control nodes.

Welcome Double Andore MK. II to the Harvestman Industrial Music Electronics lineup.

An amplifier/control module of exceptional character, this module gives dynamic amplitude control to two signal paths. To do this, it uses a pair of AD envelope generators normalized to a high-quality dual linear VCA. Each circuit element may be independently patched or used in its normalized configuration, with a mixed audio output available.

Improvements over the mark 1 version:
- Substantially increased signal quality and reliability
- Decreased panel size to 19 HP
- Dedicated shape control bends the envelope from linear to log or expo
- Much greater range of cross-modulation
- Ergonomically literate control layout to facilitate live performance
- Selectable EOA/EOC output, dedicated output attenuator, envelope VCA amount knob (per channel)
- Voltage follow/slew mode

Other features such as additional envelope stages, envelope mixing, and wavetable-based envelope curves shall become available in the future with a small expansion module.
