 The Wiard envelope generator, the Envelator
, is a multi-function dual slope linear function generator. The module contains two identical units.
The attack and decay slopes are individually voltage controllable with input attenuators. Each unit ouputs the envelope, inverse of the envelope (negative going envelope), a
voltage step signal during the attack phase, and a pulse at the end of the decay phase. The gate input has a three position switch which selects: Attack-Release where the output remains
high as long as the gate is high, Attack-Decay where the decay phase begins imediately after the attack phase regardless of the gate level or the gate input is connected to the end pulse
which causes the unit to act as an low frequency oscillator (LFO). The LFO extends into the low audio range and has triangle and square outputs. Any triangular or sawtooth shape
or pulse width can be adjusted by the attack and decay controls.
The module also contains a DC coupled voltage controlled crossfader which forms the sustain control when patched as a classic ADSR. It can also be used to mix two
modulation sources when patched as two LFOs. The crossfader will also handle audio signal through the full audio range.
The Envelator module contains:
- Two Multi-mode envelope generators/oscillators which will work in the low audio range
- A voltage "crossfader" which will work both for control voltages and audio signals
The
Envelator is available for US$CALL, and can be ordered on our Purchase
page.
