An Ornament is a sequence of up to 31 Semitone Offsets that are applied to the Pattern Note.
Each Entry holds a range of -128 to +127 in semitone steps.
A loop may also be placed on a row which tells the player to loop the Ornament when the End is reached.
The end is shown as a blank entry.
Ornaments may be used to simulate chords(commonly known as arpeggios), percussion instruments such as drums, Glissando (note sweeps) or Trills(Short ornamental riffs).
For example take a chord like C,E and G. One could simulate this by playing each in quick succession of the previous.
To accomplish this we place the C note in the Pattern and give it an Ornament. We then edit the Ornament with..
00 L +00
01 +04
02 +07
Note the E is 4 semitones above C and G is 7 semitones above C.
When playing this it may be too fast, so we would then 'space out' the change like this..
00 L +00
01 +00
02 +04
03 +04
04 +07
05 +07
Also note that the offset is always relative to the original note.
Creating a drum is a little more tricky since we need an effect to control the volume and ensure when the ornament finishes the effect has diminished the volume enough that we don't hear the end of it.
See the Cool instruments here for how to produce a drum sound.
