Polyphonic Playing with the EWV2000
By International Music Corp.

One of the most powerful features of the EWV 2000 is the ability to transmit four-note chords over MIDI to an external sound module. Programming a chord is easy. Press the Edit button and then the Tape button. The display will read "CD00 - 12:00:+4:+7". The "CD00" represents Chord #0. If you move the Value slider or the Up/Down buttons while the cursor is on "CD00", it will change numbers to the other chord positions. Up to 16 possible chords can be programmed into the EWV 2000, (CD00 - CD15). The other numbers represent the notes of the chord in relation to "Middle C". These are numbered as to the amount of semitones they are away from Middle C.

To change the number, press the Tape button again and the cursor will move under the first chord note. Move the Value slider or the up/down buttons to choose the note you want. Examples of notes are: -12 is C below middle C; -5 is F below middle C; +7 is G above middle C; and +12 is C above middle C. To program a major chord based on C, we might use the notes 12:0:+4:+7. This would give us a low C as a root, with a C-Major triad on top. A minor 7th chord might be programmed as 0:+3:+7:+10. To move to each new chord note, press the Tape button again.

After you have programmed the 16 chords you want, you can put them into a program (patch). Press the #6 Chord button, and the display will read "Chord Play: Off". Move the Value Slider up until it reads "Chord Play: On". Press the Chord button again, and the display will read "C-CHORD #00". If you continue to press the Chord button, it will select the 12 notes of the octave. The other number represents one of the 16 chords you have pre- programmed. To choose a different chord, move the Value slider or use the up/down buttons. You can place a different chord on each note of the octave with up to 12 chords possible in each program. If you want parallel chords, simply choose the same chord for each note. If you want a chord progression for a song, write in the desired chords for each note of the chromatic scale.
