Modes

Each envelope has five different modes. To change mode, click 

the corresponding channel's Mode button 

[B]

. The two mode 

LEDs 

[C]

 indicate the current mode:

02. Gated

The input accepts gate signals to generate

an attack-sustain-release envelope type.

01. Triggered

A rising edge triggers a one cycle envelope.

Time & Symmetry

Rather than having a classic attack-decay approach, the Triple 

Steeple offers control of each envelope's timing and symmetry. 

The time parameter, set via the Time potentiometer 

[D]

 and CV 

input 

[3]

, is the sum of the attack and decay time. Modifying 

the time parameter will change the attack and decay time by the 

same amount.

The symmetry parameter defines the ratio of attack and decay 

times via the Symmetry potentiometer 

[A]

. Fully counterclo-

ckwise, the envelope has zero attack time, and there is only 

decay. Turning the potentiometer clockwise reduces the decay 

time as the attack increases. With the Symmetry potentiometer 

[A]

 set at noon, the envelope is symmetrical (equal attack-decay 

times). When the Symmetry potentiometer 

[A]

 is fully clockwise, 

the envelope has an attack-only behavior without decay.
