6.3.10. Chords (Chords)
Description: In Chords mode, the Digital Oscillator is transformed into a four-voice oscillator
capable of playing chords. The fun thing is that it's possible to modulate the chord.
Chords add emotion to music. A single melodic line can evoke many emotions, but when
you add chord notes from the scale of the melody to that melodic line, the emotion will
become much stronger. When you add notes from the major scale the melody sounds
forceful and happy; add notes from the minor scale, and that same melodic line will
suddenly sound sad. At least, that might be your response if you were born in a culture
dominated by western music. In other cultures, your response to major and minor scales
may be different.
The first note of a chord is the Root. The third note in a scale determines the feel of a chord;
if it is three half-steps removed from the root, the chord is a minor chord. Four half-steps
removed from the root makes it a major chord. When you add more voices to a chord, you
are essentially fine-tuning and shaping the minor and major feel further.
Note: If you want to know more about this fascinating subject, search for music theory on a
search engine or YouTube.
Paraphony deactivates in this mode; the last key pressed is the root note, and only one
chord can be playing.
Knob functions:

Chord selection
• Octave
• 5th
• sus4
• m(inor)
• m(inor)7
• m(inor)9
• m(inor)11
• 6th and 9th added
• M(ajor)9
• M(ajor)7
• M(ajor)
Inv/Transp:
Changes the inversion and the frequency range of the chord. The chord stays
the same, but the pitches are combined differently when you move the Timbre knob or
modulate it externally.
To have an idea how this works, hold down a C major chord: C/E/G. Turn the timbre knob to
the right. At position ten you will the first inversion. Continue to turn the knob to hear other
inversions.
Waveform:
Sets the waveform. The first half of the knob goes through a selection of "string-
machine like" raw waveforms (different combinations of the organ and string “drawbars”);
the second half of the knob scans a small wavetable containing 16 waveforms.
