The Omnichord System Two makes it possible to sound like a pro even if you have never played before. This electronic musicomputer combines several musical instruments in a lightweight, portable and dynamic-sounding package.
Advanced microtechnology lets you program the background chords, rhythms, bass and drums for favourite songs without knowing one note from another. While the background plays automatically, you can add the melody line. The Omnichord can also be strummed like a guitar with the SonicStrings Strumplate. A selected chord is electronically matched to the four-octave strumplate, and every function can be used alone or in combination.
This operation manual gives step-by-step explanations of the Omnichord System Two functions. Read it carefully to make full use of the instrument.

Care and electrical safety
Precautions
Dos and don'ts to make your Omnichord last a lifetime
The Omnichord System Two uses a microprocessor to translate commands into music. Its solid-state electronic components are protected by an ABS plastic case. With a minimum of care, it should provide years of dependable operation. Always observe these precautions:
Avoid Extreme Heat
Never leave the instrument near extreme heat or in direct sunlight. Keep it away from radiators, heaters and the back-window ledge of a car.
Keep It Dry
Do not use the Omnichord near moisture or place liquids on or near it. Liquid spilled inside the instrument can require extensive repairs.
Clean With a Soft Cloth
Clean the cabinet, buttons and touchplate with a soft, damp cloth. Do not use benzine, solvents or abrasive cleaners; they can permanently damage the finish.
Turn It Off When Not in Use
Switching the Omnichord off when it is not in use prolongs battery life and reduces wear on the electronic components.
Use the Correct Power Source
Operate the Omnichord from batteries or the optional A/C adapter. Do not connect it directly to a 12-volt source such as a car cigarette lighter; this can damage the electronics and void the warranty.
Do Not Open the Instrument
To avoid electrical shock, never open the Omnichord. If service is needed, contact an authorized musical-instrument dealer. Opening the instrument also voids the warranty.

Eight size C / SUM-2 / R-14 batteries
Set-Up
Battery installation
After removing the instrument, batteries and manual from the packing carton, retain the box and packing materials. They make a useful container if the instrument must be transported later.
The Omnichord is ready to use without preparation or assembly. Alkaline batteries are recommended to reduce the risk of leakage.
Turn the Omnichord over. Use a small screwdriver or coin to unscrew and remove the battery door.
Place the fabric strap across the battery compartment as shown. It will assist with later battery removal.
Insert eight batteries according to the polarity diagram on the battery door, then close the door. If the unit has no power, re-check the battery orientation and refit the door.

Four-octave touch-sensitive strumming
Guitar: SonicStrings Strumplate
Set-up and play
The SonicStrings are electronically charged and respond instantly to a fingertip. They let you strum four octaves of a selected chord in correct pitch without strings to tune or break.
Set the controls as described for organ play, then follow these steps:
Turn CHORD VOLUME fully to the left, or off.
Set SONICSTRINGS VOICE 2, the inner knob, to about 3 o'clock. Turn VOICE 1, the outer knob, fully left or off.
Set SONICSTRINGS SUSTAIN to about 3 o'clock, or as desired.
Press a chord button with your left hand, then gently strum the SonicStrings Strumplate from bottom to top with a right-hand finger or thumb.
Multiple SonicStrings Voices
Turn VOICE 2 off and set VOICE 1 to about 3 o'clock. Press a chord and strum again to hear the wavy or vibrato voice. The two voices can be combined in any proportion; each voice knob also controls its volume.
Sustain
SUSTAIN controls the lasting resonance or decay. Turn it fully left or off, press a chord and strum to obtain a banjo-like sound.

Experiment with different strumming methods
Guitar: Playing Techniques
Slide play and touch play
The Strumplate automatically follows the selected chord, but it can be played in many different ways. Choose the method that suits the song.
Slide Play
Set SUSTAIN to about 3 o'clock and press a chord. Run a finger or thumb from the bottom of the Strumplate to the top. Repeat with two fingers, then three. Covering more surface produces a fuller chord. You may also strum from top to bottom.
Touch Play
Using the ball of a finger, pat the Strumplate in four to six places from the bottom upward. Try two, three or four fingers. Each touch can reveal a different octave. Change the voice and sustain controls to explore further variations.
Experiment to find other playing possibilities - and most importantly, enjoy making music.
