Class TestSoundfont

java.lang.Object

eu.bandm.sighkn.TestSoundfont

public class TestSoundfont
extends Object

Reverse Egineering for Sample Player.
There is a spec for "Soundfont2", but not clear what the hundreds of fields really MEAN.
So here first attempts to DISPLAY them.
For background details see sig/doc/internal/recherche_java_linux_sound.d2d
Assume "gervil" being the default synthesizer and accessible.
HACK use "gervil" classes directly. MANY WARNINGS ("may be removed")

Positive: SF2Soundbank EN/DECODES a file vs. an object structure, in a seemingly canonical way; could be a little bit more abstract, imho.

Viele "spi" = "Service Provider Interfaces" sind UNTYPISIERT ("Object")
Alle Modifikationen werden extern über "addRessource()" gemacht und intern mit "instanceof" in verschiedene Listen verteilt.
