Alternately, with ASSIGN PARAMETERS on, choose a parameter to edit with any 
of the A
SSIGNABLE PARAMETERS controls, and change the parameter’s value 
using S
ELECT or the increment (+) or decrement (-) buttons. 
Edit B/Combo — This button behaves differently depending upon the current 
mode. In Program Mode, it switches between program layers. Each program has 
two layers, A and B. Each layer can be a complete, separate patch. The layers 
are used in conjunction with the KeyMode parameter for creating stacked or 
split programs. When E
DIT B/COMBO is active, the front panel controls the B 
layer. 
Note: The A
SSIGNABLE PARAMETERS are the same for both layers. 
In Combo Mode, E
DIT B/COMBO is used to access various combo parameters. 
Press E
DIT B/COMBO once to edit voice 1 parameters. Press the button 
repeatedly to cycle through the voices and exit Edit Mode. See Combos on page 
33 for more information. 
Note: In Combo Mode or when Multi Mode is turned on in the Global 
menu, a program’s B layer is ignored. 
Pitch — Controls the base frequency of the oscillators. The relative interval 
between the two oscillators is in each voice is maintained, even when the 
extremes are reached. 
Cutoff — Controls the filter cutoff. 
Resonance — Controls filter resonance. 
Note: The filter will only self oscillate when in 4-pole mode. See Low-
pass Filter Parameters on page 19 for more information. 
Attack — Simultaneously adjusts the attack portion of all envelope generators: 
filter, amplifier, and Envelope 3. 
Decay/Release — Simultaneously adjusts the decay and release portions of all 
envelope generators: filter, amplifier, and Envelope 3. 
Push It! — The PUSH IT button is a manual trigger to play Tetra. In Program 
Mode, it can trigger a specific note (at a specific velocity) or a gated sequence, 
latch notes or sequences on and off, and manually step through a sequence. For 
more information, see Program Parameters, beginning on page 17. 
In Combo Mode, the P
USH IT button cycles through the voices for polyphonic 
combos and plays all voices simultaneously when unison is on. See Combos on 
page 33 for more information.
