;   You are now using the CLOCKWORK MUSICAL EDITOR.

; DEMONSTRATION FILE
; ================== 
; 1)  Press Alt-B to hide the crib.

; 2)  Press F1 or Esc at any time for HELP.

; This editor uses controls and commands deliberately similar
; to Sidekick and many other word-processor/editor programs.

; To get a printed copy of the editing controls:
; Press F1 and then SHIFT+PrtScr
;
; 3)  Press PgDn                                                                                                 │





; MUSIC CONTROLS
; ============== 
; What makes this editor unique is its ability to interpret
; a CLOCKWORK chord description, and other musical commands.

; 4) Move the cursor to line 38
;    (the line which reads  C 3C G E  )

; 5) Press F9
;    This should be interpreted as :
;           a chord of Crotchet duration
;           a 3rd octave C
;           a G and a E in descending order

; 6) Press PgDn                                                                                                        │

 C 3C G E



; CONTINUOUS TESTING
; ================== 
; The EDITOR can test chords successively :

; 7) Press F10
;    This will make the EDITOR work to the end of the file
;    interpreting every line.

;    Any key but S will stop testing, and bring the cursor
;    back to this point.

; 8)  Press PgDn                                                                                                             │








; DEBUGGING
; ========= 
; Using F9 or F10, the editor will report any line it cannot
; understand.  But in DEBUG MODE Alt-D it will pause at
; every error, for you to note its Line, or to Stop (S) to
; make a correction.

; It also checks that bars are of the length set by the
; TIME command.

; 9) Press Alt-D

; 10) Press PgDn                                                                                                             │







; COMPILING & TESTING PIANOLA2

; 11) Press Alt-C to have the music compiled to the roll-
;     file format, ready for PIANOLA2 to play.

;     The Roll-file will have the same name as the editor
;     but with the extension .ROL

; 12) Press Alt-R to both compile, and have PIANOLA2
;     test run the file.  You will return here.

; 13) Press Alt-X to quit the Editor                                                                                         │




; This is the music :-

   title The First Nowell  ; title is printed on roll and PIANOLA face
   head demonstration tune ; head is printed on roll
   head transposed by
   head John Worley

   Q 2E         ; Quaver, default octave=2, play an E
   Q D          ; Quaver, and a D in the default octave

; That was a short bar 'cos we started half way through it.  Debug will
;   complain, but ignore it and press any key but 'S'.

   C. 2C G E C  ; Dotted crotchet, restate default octave
   Q D C G E    ; Quaver
   Q E E *C     ; Two Es, and the remains of a Cmajor chord
