K4 // Envelope Modulator
Kilpatrick Format Envelope Generator / LFO - 1 Space
The K4 Envelope Modulator combines two envelope generators and two
LFOs into a single module. Each section supports a number of different
uses in many types of patches.
Envelope Generator Section
The two identical envelope generators can operate in one of three
modes: attack / hold / release, attack / release, and auto-repeat
mode. Both a gate input and manual trigger button can be used to start
and stop the evelopes, and the up and down times are voltage
controllable. The outputs generate both a variable voltage and a
pulse which activates during the release phase of the envelope.
A dual LFO section generates periodic signals of various speed and
amplitude. The speed can be controlled by a voltage as well as by the
panel control. The output level can be adjusted over a wide range
including the ability to internally clip the output to max and min
Both channels of the LFO section can be synchronized together and
the phase of the second channel can be adjusted ahead or behind by up
to 180 degrees. This can be used to generate waveforms which have a
known phase shift between them.
