Korg Style Structure

A style is a collection of midi sequences arranged in different elements which can be accessed using the dedicated buttons on the keyboard’s panel. These elements are the intros, variations, fills, break and endings. Depending on the model of the keyboard, the number of elements varies.

The style structure (Style and elements):

  • Style
    • Intro 1
    • Intro 2
    • Count in
    • Variation 1
    • Variation 2
    • Variation 3
    • Variation 4
    • Fill 1
    • Fill 2
    • Fill 3
    • Fill 4
    • Break
    • Ending 1
    • Ending 2
    • Ending 3

Each element has CVs (Chord variations) in it.

CV / Chord Variation

Chord variations are variants of the same pattern which are made specific for certain chord types. An element in a Korg PA arranger style can contain multiple CVs in it. By default there will be one CV. So when we record a pattern, we are actually recording in one of the CVs (The CV1 by default). The variation 1 – 4 can have up to 6 CVs in them. Other elements like intros, fills break and endings can have up to 2 CVs.

The element structure:

  • Element (Variation 1)
    • CV 1( Chord Variation 1)
    • CV 2
    • CV 3
    • CV 4
    • CV 5
    • CV 6

Each Chord Variation contains patterns in up to 8 tracks. The tracks are named DRUM, PERC, BASS, ACC1, ACC2, ACC3, ACC4 and ACC5. The tracks can be of different types based on the type of patterns used in them. Those are Drum, Percussion, Bass, Accompaniment and Guitar.

The CV structure:

  • CV 1
    • Drum track
    • Percussion track
    • Bass track
    • Acc 1 track
    • Acc 2 track
    • Acc 3 track
    • Acc 4 track
    • Acc 5 track

So the structure of a style is: Style contains elements. Elements contain 1 or more Chord Variation/(s). Each Chord Variation contains 8 tracks. So the recordings are done in tracks of chord variation(s) of elements of the style.

Why do elements have multiple CVs?

For most of the users, one CV would do. But if there needs to be more precision on different chords played in the style, we would need to create additional CVs specific for those chords which needs more precision.

When we create a pattern in a track, we would record it based on the Key and Chord type specified in the settings for the track. For example C Major. When the style is being played, the chord detected on the arranger is formed by transposing the original notes in the track. This transpose happens based on the rules set in the NTT settings for the track.

For example, in a style, the variation 1 has one CV in it. The ACC1 track has the original pattern in C major(with the notes C, E and G in it). When this style is played, if F7 chord is detected on the arranger, to generate the 7th chord, there needs to be a 4th note which is missing in the original C Major pattern. Without this 4th note, the 7th chord cannot be generated. So one note from the major chord needs to be used to form it. Depending on the NTT setting, either the root(C) or the 5th(G) of the original recording will be used to form the 7th. But the new 7th chord will only have 3 notes in it. It can either be F A E or A C E based on the NTT. If we need exactly F A C E, we can create another CV(CV2) with the original chord type as 7th and create a pattern with all 4 notes in it. Then map the CV to the chord type 7th so that when a 7th chord is detected on the arranger, CV2 will be played and for the other chord types CV1 will be played.

The similar situation happens for intros and endings where melodic patterns are recorded. There needs to be separate CVs for major and minor chords.
