Specifications

Env Delay: 0…127 — Sets a delay between the time Envelope 3 is triggered and 
when the Attack portion actually begins. 
Env Attack: 0…127 — Sets the Attack time of Envelope 3. 
Env Decay: 0…127 — Sets the Decay time. 
Env Sustain: 0…127 — Sets the Sustain level. 
Env Release: 0…127 — Sets the Release time. 
Repeat: Off, On — When on, causes the delay, attack, decay, and sustain 
portions of Envelope 3 to loop for as long as the envelope is gated on. 
Modulation Parameters 
The Modulation Parameters let you configure the modulation routing and 
amount for Tetra’s four general-purpose modulation slots as well as for MIDI 
controllers (Mod Wheel, Key Pressure, Breath Control, Velocity, and Foot 
Controller). 
Since each Tetra mod source has a single destination, the four general purpose 
Mods provide a way to send a mod source (such as a sequence or LFO) to 
additional destinations, with a different amount. There are also additional mod 
sources available here, such as Noise, allowing a wide variety of possibilities. 
To configure a general-purpose modulation slot, select the appropriate 
modulator (Mod 1, Mod 2, Mod 3, or Mod 4), and use the Source, Destination, 
and Amount parameters to route the modulation as desired. 
To configure modulation for a standard MIDI controller, select the desired 
controller and amount, and then set the destination. 
Source  — Selects a modulation source. See Modulation Sources on page 43 for 
possible sources. 
Amount: -127…+127 — Sets the amount of modulation. 
Destination  — Selects a modulation destination. See Modulation Destinations 
on page 39 for a list of possible destinations. 
Mod Wheel Amount: -127…+127 — Sets the maximum amount of modulation 
that can be applied from MIDI Continuous Controller 1 (mod wheel).
