Play your keyboard to hear how this sounds. Depending on what you’ve drawn, you
should hear a harsh and edgy digital sound.
7. Click the Mode pop-up menu, and choose Fifth (harmonics).
8. Drag the first harmonic vertically to see how the fifth harmonics only are changed,
noting that the change is relative to the first harmonic.
This is how you adjust grouped harmonics. Adjusting groups of, rather than individual,
harmonics is the best approach to take when creating additive sounds. Creating and
adjusting individual harmonics is possible (using One in the Mode pop-up menu), but it
is tedious and not an efficient approach. In general terms, even harmonics sound more
musical and odd harmonics sound noisy or dissonant.
9. Click the Tune button, choose One (single harmonics) from the Mode pop-up menu,
then draw horizontally and vertically (creating another pseudo waveform shape) in the
Partial bar display.
Play the keyboard to hear a deranged metallic sort of sound.
10. Choose Fifth from the Mode pop-up menu, then drag some points vertically and
horizontally in the Partial envelope display.
Play the keyboard to hear the fifth harmonics bend in pitch, controlled by the envelope
associated with this group of harmonics.
Harmonic envelopes control the level, pitch, pan, and phase of harmonics over time.
This level of control over each harmonic (if required) enables you to recreate almost
any type of sound, but as mentioned, it is far more efficient to work with groups
of harmonics. Individual editing of harmonics or their associated envelopes is only
recommended for fixes to unwanted partials or for more impactful edits to the lower
harmonics, such as the fundamental, second, fourth, and so on. Edits of upper
harmonics are unlikely to be audible in many cases.
