The harmony maker we will be creating will be super awesome because we will be able to choose a key for each harmonized note - or make up our own scales for each note. Sweet!
First, we will create a new Combinator, and we'll put some devices into it. Right click and select a new Combinator from the Create menu. Then drag the following items from the Tools window while holding 'shift' so nothing is auto routed.
- Line Mixer 6:1 x1
- Spider Audio Merger Splitter x 1
- Neptune Pitch Adjuster x2


Pros/Features
- Nearly unlimited harmonies.
- Parallel harmonies and key based harmonies are possible and can live side by side.
- Each harmony can have its own key or scale. You can even do crazy bitonal harmonies by setting one harmony line in the key of C and another in D, for example!
- The key or scale for each individual harmony may be user defined. Try setting one scale to a pentatonic and the other to a major scale.
Cons/Limitations
- The incoming signal must be completely dry. Signals with delay or reverb really confuse the Neptune.
- You may notice a slight delay on the harmonies. This is because of the pitch detection algorithms in Neptune. For leads, horns and strings it is not noticeable, but it is noticeable on percussive sounds.
- Live mode must be enabled which uses more CPU.
Final Thoughts
Happy harmonizing!
