Note: Outputs 3 and 4 are noticeably louder than the other two outputs. 
This is normal. Outputs 3 and 4 are always monophonic and, therefore, 
do not require as much headroom as the mix outputs, which have to 
accommodate up to four voices at one time without distorting. The higher 
level provides optimum signal-to-noise ratio. Compensate for differences 
in level with a mixer. 
Choosing “Q LR34” is similar to Quad, but voices 1 and 2 retain whatever 
panning effects are present in the assigned programs and the stereo outputs of 
those voices are present at both the Left and Right outputs. 
PotMode: Relative, Passthru, Jump –Tetra’s Cutoff, Resonance, and Volume 
controls are potentiometers or “pots.” There are three pot modes to determine 
how the synth reacts when the programmable parameters—Cutoff and 
Resonance—are edited. (Master volume is not programmable, so these modes 
don’t apply.) 
When set to Relative, changes are relative to the stored setting. In Relative 
mode, the full value range is not available until either the minimum or maximum 
value and the respective lower or upper limit of the pot’s travel is reached. 
For example, the Resonance parameter has a value range of 0 to 127. Let’s say 
the physical position of the Resonance pot is the equivalent of a value of 100. If 
you switch to a program that has a stored Resonance setting of 63 and turn the 
pot all the way up, it will only go to 90. To get to the maximum value of 127, 
you first have to turn down until the value is at the other extreme and the pot is 
at the limit of its travel (in this case, 0 and fully counter-clockwise, 
respectively). 
In Passthru mode, turning the pot has no effect until after the edited value equals 
the preset value (that is, until the edited value “passes through” the stored 
value). 
Jump mode uses an absolute value based upon the position of the pot when 
edited: turn a pot and the value jumps immediately from the stored value to the 
edited value. 
Balance V 1 - 4: -14…+14 — Adjusts the left/right balance of each voice by 
approximately +/- 4 dB. 
Basic Patch — Press the WRITE button to load a basic patch into the edit buffer. 
(The patch will not actually be written to the current program location unless 
intentionally written to memory in Program Mode using the W
RITE button.)
