Treble + bass clef rendering

[Hanns Holger Rutz]

hi there,

I need to render piano music spanning Treble and bass register. I have read in an old thread that there is a limitation with the ABC parser not producing more than one clef, but that the rendering machine should be able to display multiple clefs.

Since I already use an internal representation of notes and chords, going via the parser is anyway not necessary for me.

However, the API seems pretty restricted with respect to generating a Tune object by hand? For example the Tune class has only private constructor. So my question is: How would I create a Tune with the API (not using the Parser) and populate it with the Clefs and notes/ chords?

Thanks very much!

Best, Hanns Holger

correction—I tried the example from https://groups.google.com/forum/#!topic/abc4j/6p204Ay2OKU now and that compiles, so I was wrong about the private constructor.

so I will try to advance here first...

For instance, this naive approach (in Scala, but no different than equivalent Java code):

import abc.ui.swing.JScoreComponent
import abc.notation._

val scoreView = new JScoreComponent
val tune = new Tune()
val music = tune.getMusic

val keyT = new KeySignature(Note.C, KeySignature.MAJOR)
val keyB = new KeySignature(Note.C, KeySignature.MAJOR)
keyB.setClef(Clef.BASS)
val voiceT = music.getVoice("1")
val voiceB = music.getVoice("2")
voiceT.addElement(keyT)
voiceB.addElement(keyB)
val n1 = new Note(Note.C)
n1.setStrictDuration(Note.QUARTER)
voiceT.addElement(n1)

... will just assemble the three elements sequentially:
