DHE Modules

VCV Rack modules from Dale Emery

The Modules

The DHE-Modules suite includes envelope generators, logic modules, low frequency oscillators, utilities. and waveshapers.

Envelope Generators

Composable Envelope Generators

_Stage_ _Booster Stage_ _Hostage_ _Upstage_

Stage generates a single envelope stage. Combine Stages and other modules to generate complex envelopes with any number of stages.

Booster Stage enhances Stage’s functionality, adding CV inputs, sigmoid curves, buttons to inject triggers and other control signals, and more.

Hostage generates a hold or sustain envelope stage.

Upstage adds special-purpose envelope controls to inject triggers, suppress retriggers, set an envelope’s starting voltage, and more.

Multi-Stage Envelope Generators

_Curve Sequencer 4_

Curve Sequencer 4 is a four-step envelope generator that offers control over the individual steps and the overall sequence. Curve Sequencer 8 and Curve Sequencer 16 expand the same functionality to even more steps.


_Fuzzy Logic H_ _Fuzzy Logic Z_ _Gator_

Fuzzy Logic H combines signals by applying fuzzy logic operators based on hyperbolic paraboloids.

Fuzzy Logic Z combines signals by applying fuzzy logic operators defined by Lofti Zadeh.

Gator computes eight common logic functions for up to 16 inputs.

Low Frequency Oscillators

_Blossom_ _Xycloid_

Blossom traces a point around the edge of a circle as the radius of the circle varies.

Xycloid traces a fixed point on the edge a circle rolling along the inside or outside of another circle.

Each draws a pleasing, two-dimensional shape, generating a pair of complex, evolving, pulsing LFO signals.


_Cubic_ _Func_ _Func 6_ _Ranger_ _Tapers_

Cubic offsets, scales, squares, and cubes its input signal.

Func is a knob with a selectable range to offset or scale its input signal.

Func 6 is a chain of knobs with selectable ranges to offset and scale input signals.

Ranger is a modulatable knob with an adjustable, modulatable range.

Tapers is a pair of modulatable knobs with adjustable, modulatable tapers.



Swave is a waveshaper with a unique sigmoid transfer function.
