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 illustration, 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 depressed. Return the knob to center.
Raise the portamento slider about halfway and play a short melody; note the "glide" between pitches. The position of the portamento slider determines the speed of the glide; experiment 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 centered, 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.
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 is 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 inserting the foot pedal jack.) See Patch 1 and 2 for examples of its use.
Your Odyssey keyboard has two-voice capability. 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 independent 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 11 position.)

HINTS FOR GETTING THE MOST OUT OF
YOUR ODYSSEY
1. You may tend at first to think of the control 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.
2. The patches given in this manual are very basic. Do not hesitate to search for improvements and variations on your own. In 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.
