1 OPERATION OF QUADRA COMPOSER
==============================
Some text that (probably) nobody will read anyway, describing the
user interface of QuadraComposer follows...
1.0 GADGET TYPES (some...)
==========================
The gadgets are not StyleGuide compliant, but we are working on a
FULLY intuitionalized release (will probably NOT work on 1.2/1.3
though :) that will be more SG compliant...
1.0.1 UP/DOWN GADGET
====================
+--+
| /|
|/ |
+--+
Pressing the LMB over the up/down-wards pointing triangle will
in/de-crease the value in the resessed box beside. If the RMB is
pressed simutaneously, the rate of change will increase.
1.0.2 CYCLE GADGET
==================
+---+
|/->|
|| |
|\-/|
+---+
Cycles through multiple choices then clicked on with LMB.
1.0.3 TEXT(STRING) GADGET
=========================
A box with text in it. Click LMB to edit, [ENTER] finishes...
1.0.4 LITTLE RED DOTS
=====================
If a gadget has a little red dot in its upper right corner, then
there is an option window attached to it. Clicking RMB brings it up.
1.1 SCREEN OVERVIEW
===================
The screen is divided in five main areas, which are described below.
+-----------------------------------------------------------+
| TITLE BAR |

+-------------------------------------+--+
where x.yz is the version of Quadra Composer and:
a -/M MULTI off/on
b -/E AUTOECHO off/on
c 0-9 EDITSKIP value
d -/1 CHANNEL 1 off/on
...
g -/4 CHANNEL 4 off/on
1.1.2 SIDE MENU
===============

There are four of these, from top to bottom;
SONG NAME (used as default basename of the module when saving)
PATTERN NAME (useful when mixing the patterns)
SAMPLE NAME (used as default basename when saving)
STATUS LINE (status of the last operation)
1.1.4 SPECTROSCOPE
==================
The fun-to-look-at(tm) part of Quadra Composer (for us poor guys who
can't create any music worth listening to anyway...) it's a combined
spectrumanalyzer and a kind of oscilloscope. Toggles mode with a
mouseclick. (The spec.analyzer is kind of "cheap" (no fft); but it
works remarkably well ;)
1.2.1 PATTERN EDITOR
====================
The window is divided into four vertical areas, tracks, representing
one audio channel each. RMB click toggles the channel on/off
(indicated by the title bar). LMB click moves the cursor to selected
point (row, note/effect). LMB drag marks a block.

2 QUADRA COMPOSER EFFECT COMMANDS
=================================
The effect command is the last three (3) digits of each row of a
track.
| C 101xyz |
^^^^^^^^
\|/|| \\____Effect command
| \_______Sample number
\_________Note.
2.1 Command 0yz: ARPEGGIO
=========================
Arpeggio is a rapid pitch change. The pitch changes between the
played note and the notes Y resp. Z halftones higher.
2.2 Command 1yz: PITCH SLIDE, UP
================================
Slides the pitch up YZ halftones. The resulting pitch cannot be
higher than the highest possible pitch (B 3).
2.3 Command 2yz: PITCH SLIDE, DOWN
==================================
Slides the pitch down YZ halftones. The resulting pitch cannot be
lower than the lowest possible pitch (C 1).
2.4 Command 3yz: TONE PORTAMENTO
================================
Slides the pitch up/down to played the note at YZ halftones per
frame. The effect must be reactivated on each row. If YZ=00 then the
last YZ will be used.
| C 101000 |
| C 201302 |
| 00300 |
| 00300 |
| ... |
When the desired pitch is reached, the effect will not do anything.
2.5 Command 4yz: VIBRATO
========================
Makes a vibrato effect on the sample played. The command must be
reactivated on each row. Y is the speed of the vibrato and Z is the
depth. If an argument is "0" then the previous value used will be
used.
| C 101445 | +-------------------------------------+
| 00406 | <--| Makes the vibrato deeper and deeper |
| 00407 | +-------------------------------------+
| 00408 |
| 00409 |
2.6 Command 5yz: VOLUME SLIDE + SUSTAINED TONE PORTAMENTO
=========================================================
Adds a volume slide to a tone portamento. The portamento must be
initialized with the [3yz] effect before this effect can be used. The
Y argument represents the volume increase rate and Z the decrease.
| C 101000 | +--------------------------------------+
| C 201305 | <--| Continues the portamento and slides |
| 00501 | | the volume down |
| 00501 | +--------------------------------------+
|... |
2.7 Command 6yz: VOLUME SLIDE + SUSTAINED VIBRATO
=================================================
Similar to command [5yz], see above. The vibrato should be
initialized before using this command.
2.8 Command 7yz: TREMOLO
========================
Creates a volume vibrato. The speed is set with the argument Y and
the depth with Z. If an argument is "0" then the last value for that
argument is used.
2.9 Command 8yz: NOT USED
=========================
2.10 Command 9yz: SET SAMPLE OFFSET
===================================
Used only when a note is played, to skip a bit into the sample. The
argument YZ is multiplied with hex 200 and that many bytes of the
sample are skipped.
| C 101923 | <--| Skips hex 23 * 200 = 4600 bytes |
NOTE: This differs from the NT-format, where the offset was hex
YZ*100.
2.11 Command Ayz: VOLUME SLIDE
==============================
Slides the volume up at the speed set by Y or down at the speed set
by Z. The effect must be reactivated on each row.
| C 207A20 | +-----------------------+
| 00A20 | <--| Slides the volume up. |
| ... | +-----------------------+
2.12 Command Byz: POSITION JUMP
===============================
Skips the rest of the current pattern (It's a good idea to pull the
length down to save some bytes of memory...) and jumps to position
hex YZ.
NOTE: This differs from the NT-format, where the argument to this
effect was given as a decimal number.
2.13 Command Cyz: SET VOLUME
============================
Set the volume for a channel. The argument YZ sets the new volume.
The volume must be between hex 0 and 40.
2.14 Command Dyz: PATTERN BREAK
===============================
Skips the rest of the current pattern (see command Byz) and the first
YZ rows of the next pattern (YZ should not exceed the length of the
next pattern).
2.15 Command Eyz: EXTENDED (E-)COMMANDS
=======================================
The e-commands are explained below.
2.16 Command Fyz: SET SPEED/TEMPO
=================================
Sets the speed of a pattern (and the ones that follow...) if the
argument YZ is less than or equal to hex 1F or the tempo if YZ is
higher than hex 1F.
The speed is normally the number of picture frames or vertical blanks
(1/50 second PAL or 1/60 second NTSC) to wait between each row of a
pattern. The default speed is 06, ie 0.12 seconds (PAL) or 125 beats
per minute.
If the tempo is set QuadraComposer will switch from VBL timing (125
bpm, PAL) to CIA timing. The default tempo is hex 7D (125 bpm,
again). The tempo rating assumes a default speed setting.
TECHNOTE: If the tempo is set to anything else than 7D, then the
level 6 CIA interrupt must be used. If the tempo is set high then the
replay takes more time each frame (the replay interrupt also will get
out of phase with the screen refresh, so worst case time consumtion
can get high (or at least unpredictable) even when using lower tempo,
check the replay routine...).
2.17 EXTENDED COMMANDS
======================
2.17.1 Command E0z: SET FILTER
==============================
Used to switch the internal audio filter on or off. If Z is "0" the
filter is switched on and if Z is "1" the filter is switched off.
NOTE: Some old amiga's don't have this feature.
2.17.2 Command E1z: FINE PITCHSLIDE, UP
=======================================
Slide the pitch up a little bit, Z is simply added to the pitch.
2.17.3 Command E2z: FINE PITCHSLIDE, DOWN
=========================================
As above, but down.
2.17.4 Command E3z: SET GLISSANDO
=================================
Turn glissando on (Z = "1") or off (Z = "0"). Glissando is used with
portamento. If it is turned on, then the portamento will be done
halftone by halftone, like "walking" up or down the piano.
TECHNOTE: This effect can use up a lot of time, check the replay
routine...
2.17.5 Command E4z: SET VIBRATO WAVEFORM
========================================
Simply selects the waveform used for vibrato effects. Z=0 Use
sinewave (default) Z=1 Use ramp down Z=2 Use squarewave
2.17.6 Command E5z: SET FINETUNE VALUE
======================================
Sets the finetune value for a channel. The finetune can vary from -8
to 7 (using 2's complement, ie 0 to 7 are represented by the numbers
0 to 7, and -8 to -1 are represented by the numbers 8 to F).
| C 101E5E | <--| Set the finetune value to -2 |
2.17.7 Command E6z: PATTERN LOOP
================================
Used for creating loops in patterns. First the first row of the loop
must be defined, by using Z = 0, and then at the end of the loop, the
number of "jump backs" are defined with Z > 0. Nested loops (inside
eachother) are not possible.
| C 303E60 | <--| Beginning of the loop |
| ... |
| 00E64 | <--| The loop will be replayed 4 times, then |
| continue |
2.17.8 Command E7z: SET TREMOLO WAVEFORM
========================================
Like command E4z, but sets waveform for tremolo instead.
2.17.9 Command E8z: NOT USED
============================
2.17.10 Command E9z: RETRIG NOTE
================================
Playes the note every Z VBL's (see effect Fyz). Useful is you want to
play the pattern slowly, but want say, a hihat playing rapidly.
2.17.11 Command EAz: FINE VOLUMESLIDE, UP
=========================================
Simply adds the argument to the current volume of the channel.
2.17.12 Command EBz: FINE VOLUMESLIDE, DOWN
===========================================
Simply subtracts the argument from the current volume.
2.17.13 Command ECz: NOTECUT
============================
Cuts the note after Z VBL's (see effect E9z), ie sets the volume to
00.
2.17.14 Command EDz: NOTE DELAY
===============================
Waits Z VBL's, before playing the note.
2.17.15 Command EEz: NOT USED
=============================
2.17.16 Command EFz: PATTERN DELAY
==================================
Delays the pattern Z VBL's. Useful for creating a short pause in the
music.
2.18 EFFECTS THAT DIFFER FROM THE NT-FORMAT
===========================================
Some effects differ slightly from the nt-format. These are effect
9yz, and effect Byz. These differences are autimagically converted
when a module is loaded/saved in NT-format.
