Choosing the Key and Scale
With Scale harmonization, all of the chords in an entire song and your mel-
ody can belong to a single key. You can input this key by using the Key pa-
rameter.
Use the
Scale parameter to choose a type of scale for the harmony notes.
You can choose between 3 Major and 3 Minor alternate scales that can be
chosen if your harmony intervals sound incorrect at certain chord/melody
combinations.
When the match of Key and song is correct, a Scale harmonization is nearly
indistinguishable from recorded harmony. There are limitations however:
▪ Scale works for many, but not all songs.
▪ Scale works best with 3rd harmony intervals ( Voice > Scale parameter); add-
ing the 5th reduces the number of compatible songs.
You should be singing with musical backing and stay true to a A=440Hz ref-
erence. This could be a recorded song or other musicians. Choose a simple
song to start with. Determine the key of your song; this is often the first or
last chord in a song without extensions. For example G Major is a valid key,
Gm7b5 is not.
If you’re lucky the first time, you’ll be rewarded with soaring harmony over
your whole chorus or song. If not, you can try the following:
▪ Try a different Key, perhaps a 5th away from your first choice.
▪ Choose a different Major or Minor alternate Scale.
▪ Choose a Set with only the 3rd (High) interval.
Adjusting the level
▪ Use the Level parameter to adjust the level of the Harmony effect.
Setting portamento time
▪ Use the Portamento parameter to set the portamento time.
Portamento is a delayed response to the pitch movement of your singing
voice. It is also referred to as ‘Glide’ in synthesizers. The range of values
equals approximately how long the upwards or downwards slide will take to
reach each new note.
