General Functions Overview

1. Mode Toggle:

If the 

mode toggle

 is in the left position, then the Envelope mode is selected.

If the 

mode toggle

 is in the center position, then the Oscillator mode is selected.

If the 

mode toggle

 is in the right position, then the Noise mode is selected.

Note:

By default, envelopes must be triggered via the 

trig in

 or the 

trig button

. To set

Envelope mode to cycle, causing envelopes to retrigger at the end of the decay 
segment, press and hold the 

trig button

 for 2 seconds. Repeat this process 

to return to the default setting. When envelopes are set to cycle, their phase 
will be reset by inserting a gate signal into 

trig in

 or by pressing the 

trig button

.

2. Nrm/Alt Toggle:

When Envelope mode is selected and the 

nrm/alt toggle

 is in the left position, 

envelopes are linear. 

Envelopes are exponential when the 

nrm/alt toggle

 is in the right position.

When Oscillator mode is selected and the 

nrm/alt toggle

 is in the left position, 

the pitch tracking of this square wave oscillator is 1V/Oct. 

Pitch tracking of the square wave oscillator is quantized to semitones when the 

nrm/alt toggle

 is in the right position.

When Noise mode is selected and the 

nrm/alt toggle

 is in the left position, noise 

will continuously output.

When the 

nrm/alt toggle

 is in the right position, enveloped noise will output when

the EON's 

trig in

 receives a gate signal or the 

trig button

 is pressed.

3. Trig In

:

Threshold 2.5V

Trigger input for linear and exponential envelopes in Envelope mode.

Trigger input for reset of the envelopes when cycling is activated. 

Trigger input for reset of the triangle wave LFO in Oscillator mode.

Trigger input for enveloped noise in Alternate Noise mode.
