9. Before continuing, defeat the oscillator modulation by turning off switch (A).
other controllers
10. The PITCH wheel (28), located next to the MODULATION wheel to the left of the key-
board, is used to bend the pitch determined by the keyboard (as much as half an octave up
or down) when the performer wishes to introduce expressive nuances to individual notes
during performance. Depress a key, and move the PITCH wheel back and forth with your
left hand. Notice that you can reset the control by feel − a detent mechanism holds it in
its normal center position.
11. The TUNE control (1) is used to tune up the Mini Moog oscillators to the pitch of the en-
semble in which it is being used, or to its A-440 reference tone. Check to see that switch
(C) is on, and notice that, when a key is depressed, the pitch moves up and down by a few
tones as the TUNE control is turned through its range. Make sure the PITCH wheel is in
its center position, and turn on the A-440 switch (Q). Depress an A key on the keyboard,
and adjust the TUNE control so that the two A's are in tune with each other. Turn off the
A-440. The other two oscillators may now be tuned to Oscillator 1 using their FRE-
QUENCY controls.
12. The GLIDE control (2) regulates the amount of portamento, or glide, heard between
pitches as first one key and then another is depressed. This control is activated by turning
on the GLIDE switch (R). Setting the GLIDE control at various levels, play a scale or ar-
peggio, first with the GLIDE switch on, then using the switch to introduce glide selec-
tively between certain notes only. Notice that the further to the right control (2) is set, the
longer it will take a tone to move from one pitch to the next.
13. Finally, the KEYBOARD itself functions as a controller. It produces a control signal
which varies according to the position of the key struck. If more than one key is held
down, only the lowest one has effect. The control output of the KEYBOARD is perma-
nently connected to Oscillators 1 and 2. Switch (B) couples it to Oscillator 3. Switches
(K) and (L) couple it to the filter, and are discussed in the section titled modifiers, step 8.
The KEYBOARD also produces a timing signal each time a key is depressed. This will
be discussed in the modifiers section in connection with filter and loudness contour con-
trols.
