The Envy Machine is a 4 channel modulation source. Each channel can function independently as one of the following:
- ADSR Envelope
- AD envelope
- AD LFO
- Random Voltage
- Recorded knob movements
Each channel has a CV input for modulation, and you can assign the parameter to be modulated. In addition to the input CV, there is an attenuverter for the output, and you can set the output level and sign. You can also control the shape of the envelope and LFO. All of this is set by encoder and button operation.
In Envy Machine, after selecting a channel, you can set the operation mode and parameters. To select a channellight bluePress the button several times until the LED above the jack for the channel you want to set turns red.
Each channel can operate independently in one of five modes:
The mode of the selected channel islight blueHold down the buttonGrayPress the button. In each mode, the LED bar will light up and the parameters will be as follows:

Bar2: Mod CV attenuverta
Sets the strength and direction of the Mod CV effect. It is set to zero in the center.
Bar3: Waveform control
Morphs between the following waveforms:
SQUARE
The signal is clipped and converted to a square wave. Between this waveform and SINE, it becomes closer to a trapezoidal waveform. In random voltage mode, a step-like voltage is output, and the change is delayed as it approaches SINE. In AD envelope mode, a gate of the decay length is output at the end of the attack, which can be used as a gate delay.
YES
Maps the signal to a sine wave (SINEWAVE). Values between this and EXPO produce waveforms that are closer to a linear waveform (triangle wave).
EXPO
Maps the signal to an exponential waveform. The rise and fall times accelerate, creating a smooth, accelerating movement. Good for expressive, slow attacks, like those in a flute.
LOG/EXPO
Maps the signal to a classic envelope curve. Has a rapid logarithmic rise and a sharp exponential decay, suitable for traditional percussive, sharp envelopes.
Bar4: Output attenuverter
Sets the output attenuverter. The center position is zero.
Apart from the fifth knob recording mode, which outputs knob movements as CV, every mode has the ability to record the movements of each parameter and play them back in a loop. To record knob movements,light blueHold down the button and move the knob. Click the encoder to start and stop the recorded knob movement. The recorded knob movement will be retained even when the power is turned off.
