transpose, portamento, and pitchbend controls

(Figure X) give extra flexibility to your pitch

control of the oscillators.

Set the controls, to start with, as in the

illus-

tration, and feed VCO 1 (either the sawtooth

or pulse signal) into the audio mixer with the

VCF, HPF, and VCA wide open.

Depress a

key and rotate the pitch bend knob to the

right, then to the left, then return it to center.

Release the key and rotate the knob again.

Note that it operates only when a key is de-

pressed. Return the knob to center.

Raise the portamento slider about halfway

and play a short melody; note the "glide" be-

tween pitches. The position of the portamento

slider determines the speed of the glide; exper-

iment with different settings.

The transpose switch shifts the entire keyboard

control up or down by two octaves. Play a

scale up the keyboard with this switch cen-

tered, and then with the switch up, then with

the switch down.

In this way the keyboard

can have an effective range of seven octaves,

almost as wide as a piano.

Keyboard

pedals

The foot switch supplied with your Odyssey is

used to turn on the portamento.

Thus

you can

set the portamento slider for a certain glide

speed and then turn it on and off with the

foot switch.

When the foot pedal

plugged into the back

of your Odyssey, VCO 2 and the VCF can be

controlled by it.

(The signal from the 5/H

mixer is automatically disconnected by insert-

ing the foot pedal jack.) See Patch 1 and 2 for

examples of its use.

Your Odyssey keyboard has two-voice capa-

bility.

Feed both oscillator signals into the

audio mixer and tune them to unison while

holding down the

lowest

key.

Now VCO 1

will follow, or "track," the lowest key of any

two notes you play, and VCO 2 wil I track the

highest key. Thus you can play two indepen-

dent pitches at the same time. For examples

of this turn to page 20 and begin with the first

patch. (When you are setting up a two-voiced

patch, make sure the "sync,, switch is in the

"off

position.)

HINTS FOR GETTING THE MOST

OUT OF

YOUR

ODYSSEY

You may tend at first to think of the con-

trol sliders on the Odyssey as something like

stop tabs on an electronic organ. That

is,

you

may be

tempted

to set them in a certain way

and then "play" the Odyssey only from the

keyboard.

Try

to overcome this temptation.

Use the sliders in performance.

Learn to

change the sounds you are producing while

you are producing them.

The

patches given

this manual are very

basic. Do not hesitate to search for improve-

ments and variations on your own.

many

cases a slight change in the position of a single

control slider or attenuator can make a large

difference in the sounds you are producing.

3. Resist the temptation to merely open as

many sliders as possible, as far as possible.

It's a variable synthesizer: vary it!
