Rhapsody4 Data Structure
~~~~~~~~~~~~~~~~~~~~~~~~
Rhapsody 4 files differ from earlier versions in the following
major ways.
* They are fully word aligned
* They use lettered identifiers to make slots and data more easily
recognizable
* Block lengths are now allocated two bytes. Data lengths are now
allocated one whole byte. This means that there are effectively no
restrictions on the number of notes in a slot or the length of data
items
* A large number of restrictions have been removed
Overall structure

Block types
~~~~~~~~~~~
**SC 43532A2A contains data about the whole score
**ST 54532A2A contains data about a particular stave
**SY 59532A2A contains data about a system (ie a line)
**HD 44482A2A contains data about the titles
**SL 4C532A2A contains data about a data slot
**EX 58452A2A contains exclusive data
Every Rhapsody file must start with a **SC block followed by the
correct number of **ST blocks. Next comes at least one **SY block and
the **HD block. These are followed by any number of **SL blocks
interspersed with (optional) **SY blocks.
All current and future versions of Rhapsody ignore **EX blocks.
Every file must end with ****.

28-31 MIDI port number (0-3) 0
Note that, unlike Rhapsody3 which allocates a unique set of
internal voice channels to each stave, Rhapsody 4 lumps all
staves which use the same voice together. It then allocates
as many channels to that voice as possible using the number
of sound channels specified as a minimum.

2d. pitch map
This is an array of 128 bytes which map one pitch on to another.
The set is optional depending on bit 25 of stavedata1.
The **SY block
~~~~~~~~~~~~~~
A **SY block contains data about a musical system - ie a line
of music on a page. Every Rhapsody file has at least one **SY block which
prints the score in linear mode. Other sets of **SY blocks are created
and maintained as required. Each set has a format number. The linear
mode **SY block has format number = 0. The **SY block is the block which
actually prints the staves, the clefs and key signatures. **SY blocks
may contain slot data but this is not recommended as this data will be
lost if that particular format is deleted. Only the first **SY block
of a set in the file contains an FD data block. The linear mode **SY
block does not contain an FD data block.

Notes
~~~~~
[*] Flags marked with a * are set by Rhapsody automatically and can
be ignored (or set to zero) by other programs
5. Graphics coordinates
Many data items have associated coordinates. These are specified
in a single word as two signed 16 bit integers
&xxxxyyyy
xxxx x coord offset
yyyy y coord offset
offsets are measured in OS units from the point where the note
line intersects the stave line with the exception of the left square
bracket where the offset is measured from the front of the slot
Notes on creating a simple R4 score
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The first 4 words should be
&50414852 RHAP
&59444F53 SODY
&30302E34 4.00
&0000000D <CR>
The **SC block should look like this
&43532A2A **SC
&40000054 bit 30 must be set, bit 31 must be unset so that R4 will
recalculate all slot widths and flags on loading
&00000028 offset to font list
&000000nn nn = number of staves
&00000077 play options
&00000064 playing speed
&00002509 midibeat options
&00000030 print options
&0000llll llll - score length in bytes
&00000000 can be ignored if bit 31 unset above
&40800101 midibeat pc data
&01010100 initial bar and page numbers
&0000000C offset
&6E697254 body font 1 (Trinity)

&6E6F7472
&0000000D
&00000008 offset
&0D3EA93C Copyright notice (<⌐>)
The there should be a number of stave slots eg:
&54532A2A **ST
&0000003C length of slot
&00000010 offset
&08434020 stavedata1
&40000000 stavedata2

&00000008 offset
&0000000D stave name (blank)

&00000014 offset
&69727453 stave voice
&694C676E
&6F532D62
&000D7466
There follows a system slot:
&59532A2A **SY
&0000002C length (&28 + 4*number of staves)
&00000010 slot width
&08004453 SD code (length 8)
&00000000 extra OS units
&00000000 extra OS units
&00000190 left hand indent
&FFFFFFB0 vertical indent (negative)
&FFFFFFFF stave selection (all)
&FFFFFFFF stave selection
&00600060 stave heights (repeated as necessary)
... "
and a blank header slot:
&44482A2A **HD
&0000000C length
&00000000 (not used)
Now the data slots of which this is an example:
&4C532A2A **SL
&00000014 flags = 0, length &14
&00000000 slotwidth (will be calculated by R4 on loading if
bit 31 above is unset)
&02014C43 clef code CL, stave 1, length 2 words
&00000001 treble clef
The end of the file is terminated with
&2A2A2A2A ****
Other points
~~~~~~~~~~~~
If bit 31 of the score flags is unset, R4 will inspect every slot in
the score on loading and reset certain flags etc. These include
the score flags (bits 29-31)
bits 29 and 30 of the slot flags
all slot width and timing information
the 'previous clef' number
the 'previous key signature' number

R4Player messages
~~~~~~~~~~~~~~~~~
R4Player is a Wimp application which has no windows or menus.
Its function is to play Rhapsody4 files or MIDIfiles and to generate
MIDI files on request from another application. It responds to the
following messages with the associated parameter blocks described.
Normally, applications will issue an 'Are you here' message.
If this message is returned empty, they should start up R4Player from
their own resources. R4Player keeps track of which applications have
requested its services and when all such applications have died, it
will kill itself.
PLAY% &506C0 (plays a Rhapsody4 or MIDI file)
20 pointer to start of score
24 pointer to play position
28 dynamics map
32 recording flag (TRUE during real-time capture)
Note, in the case of Rhapsody4 files, the play position
pointer does not have to point to a slot, R4Player scans ahead to find
a slot to play. In the case of MIDI files, only the start pointer is
relevant.
MIDI% &506C1 (generates a MIDI file)
20 pointer to start of score
24 pointer to start of output block
28 dynamics map
32 MIDI format (0 or 1)
PAUS% &506C2 (Pauses playing temporarily)
SPED% &506C3 (Changes the tempo)
20 Speed (100 = normal speed)
HALT% &506C4 (stops play immediately)
No data required
R4PL% &506C5 (are you here?)
This message is broadcast by any application interested in
using R4Player. If present R4Player notes the task handle of the
application and responds with a HELO message.
PMSF% &506C6 (generates a PMS file)
20 pointer to start of score
24 pointer to start of output block
SDAT% &506C7 (sends stave data)
20 stave data for all staves (1 word each)
R4Player issues the following messages:
MESS% &506D0
20 message text
POSN% &506D1 (Sends position)
20 x coordinate (R4 files only)
24 % of file played
This is used by Rhapsody4 to scroll the window during play.
STPD% &506D2 (Play stopped)
No data required
This is issued if, for any reason, R4Player has to stop
playing.
DONE% &506D3 (MIDI file created)
20 start of MIDI file (inclusive)
24 end of MIDI file (exclusive)
This is issued when a R4Player has finished creating a MIDI file.
HELO% &506D4
No data required
This message is issued in response to an 'are you here?'
message. It is also issued when R4Player is started up to let
applications know that it has arrived.
PMSD% &506D5 (PMS file created)
20 start of PMS file (inclusive)
24 end of PMS file (exclusive)
This is issued when a R4Player has finished creating a MIDI file.
Other messages:
&506E0 (Midi string)
20 midi string
R4render
~~~~~~~~
R4render is a relocatable module which will render a
Rhapsody4 score or produce a drawfile. It respondes to a single star

defined as follows
block%!0 pointer to base of score
block%!4 view scale (%)
block%!8 format number
block%!12 page number (first page is zero)
block%!16 x origin
block%!20 y origin
block%!24 pointer to cursor
block%!28 cursor stave

1 = printing hardcopy
2 = create drawfile
block%!56 1,2 = normal cursor
3 = drop mode style
4 = step capture style (both tails)
5 = step capture style (up tails)
6 = step capture style (down tails)
block%!60 block start pointer
block%!64 block end pointer
