1 Counter to next Info Byte / 0 not stored, next Info Byte in 1 Tick
Wenn ein Bit im Info gesetzt ist ein Daten Byte f<>r den Eintrag
gespeichert bei Effekten sind 2 Daten Byte (Effekt Nr. und Effekt Daten)
gespeichert.
Counter ist ein Z<>hler in Ticks bis zum n<>chsten Info Byte wenn Counter Bit
in Info = 0 dann ist f<>r den n<>chsten Tick wieder ein Info Byte
vorhanden.
Effekt Gruppen:
INSTRUMENT: Jump Position, Loop Controll, Reverse, Scratch, Filter
NOTE: Portamento, Tremolo, Vibrato, Arpeggio
VOLUME: Set, Slide, Tremolo, Vibrato, Arpeggio, Stereo
Es k<>nnten also maximal 3 Effekte gleichzeitig ausgel<65>st werden jeder in
einem anderen Bereich. Maximale Gr<47>sse eines Track Eintrags sind 11 Byte
(Info=0FEh).
Def.: Note
0 = Keine <20>nderung
1-108 = Note in Halbtonschritten, C0=1 bis H8=108
Dies entspricht einer Midi Note mit 1 addiert
109-128 = nicht defined
129-236 = Set Note Buffer
Die Note wird in den Note Buffer gespeichert und nicht
gespielt, eine spielende Note wird dabei nicht ver<65>ndert.
Das MSBit wird gel<65>scht die Noten entsprechen dann den
Noten 1-108.
Der Note Buffer wird als 2 Parameter f<>r Note Effekte
verwendet z.B. f<>r Tone Portamentos wo die Effekt Daten
schon f<>r den Steigungsgrad vergeben sind.
Note Buffer k<>nnte man auch dazu verwenden um Noten aus
zuklammern, also um auszuprobieren wie sich das St<53>ck
ohne diese Note anh<6E>rt ;-)
237-254 = nicht definiert
255 = Note Off
Def.: Volume
0 = keine <20>nderung
1 - 255 = Volume (255=Max Volume, linear Scale)

Das DMF Format ist somit folgende Bl<42>cke unterteilt:
[DDMF] Format Kennzeichnung. The almighty DELUSION DIGITAL MUSIC FORMAT ;-)
[INFO] Info wird nur wenn n<>tig gespeichert. Defintion fehlt...
[SEQU] Sequencer, solange wie der Block
[PATT] Pattern Data, es ist f<>r jeden Pattern eine beliebige Track Zahl
m<>glich sonst werden bei 16 Spuren z.b. in einem Pattern nur 4 ben<65>tzt
werden zuviel Overhead gespeichert.
[SMPI] Info der Samples.
[SMPD] Daten der Samples. Sollte nach dem SMPI Block gespeichert sein.
[ENDE] Letzter Block im File ;-)
