Events

OScofo for now supports four events, NOTE, TRILL, CHORD and REST. Before define then, I need to explain how to represent PITCHES and DURATIONS.

Check the MusicXML Importer

OScofo has a MusicXML importer, it is very accurate and tested on MuseScore and Sibelius (but should work for all major programs).

Pitches and Durations

PITCH

On OScofo pitches are represented by name or MIDI.

  • NOTENAME: Things like C4, Db5, C#5, Gb5, etc...
  • MIDI: Normal MIDI. 60 for C4, 67 for G4, etc...

DURATION

Different from Antescofo, on OScofo you just represent <DURATION> using number of tempos.

So fraction representation is not support, mainly because something like 1 is ambiguous with 1/1. And, for me, in fraction will be necessary to define the Time Unity to be a more precise language.

Because that OScofo uses time representation relative to the value of BPM define previously. For example, if in your score you have the BPM set as = 60 this means that

  • duration value is 2;
  • duration value is 1;
  • is 0.5,
  • is 0.25

if in your score you have the BPM set as = 60 this means that

  • duration value is 4;
  • duration value is 2;
  • is 1,
  • is 0.5

For duration with dot, you sum it.

Compound Time Signatures

Avoid to use Compound Time Signatures as = 60, because this means that the will be equal to 0.33, prefer to use = 180.

Events

NOTE

NOTE events describes normal pitches. It must be defined as NOTE <PITCH> <DURATION>.

  • NOTE C4 2
  • NOTE 60 2
  • NOTE C#5 0.3
  • NOTE Bb3 0.25

TRILL

TRILL events describes trill and tremolo events. It must be defined as TRILL (<PITCH1> <PITCH2>) <DURATION>.

  • TRILL (C4 D4) 2
  • TRILL (60 67) 2
  • TRILL (C#5 E5) 0.3
  • TRILL (Bb4 D5) 0.25

CHORD

CHORD events describes chord, stable multiphonics, and others events. It must be defined as CHORD (<PITCH1> <PITCH2>) <DURATION>.

  • CHORD (C4 E4 G4) 2
  • CHORD (60 64 67) 2
  • CHORD (C#5 E5 Ab5) 0.3
  • CHORD (Bb4 D5 F4) 0.25

REST

REST events describes rests. It must be defined as REST <DURATION>.

  • REST 0.2
  • REST 4
