With this software you'll be able to produce high quality soundtracks for use in your own work, by using the interrupt feature provided, write tunes with the easy-to-use track editor, and create new instruments with the extensive sound editor.

Using Boo-Tracker

The program itself is of a menus design, using the up and down arrows to pinpoint an option, and SPACE to select it. At all times, pressing ESC will take you back to the previous menu, and
so if you press it enough times, you'll eventually return to the main menu.

How The System Works

Tunes are constructed in blocks of notes called sequences, which contain a riff likely to be repeated throughout the tune, though not necessarily. These sequences are then tied together and given a running order, and so a tune may be built up from simpler blocks, without re-typing repeated sections, etc.

Each sequence contains 64 steps, each step consisting of either silences, sounds, or a mixture on the three channels. There can be 16 sequences in total, with a running order of 256 items. This means that these 16 sequences can be repeated and played in various orders, without lengthy re-writing. The lengths of the sequences may be altered, allowing various time signatures, not just 4/4.

The actual notes sounded can be played on different instruments, of which there are 14 in total. These instruments are defined with sound and envelope waves, using the instrument editor provided.

If all this seems a little daunting, there's
already a music file on the disc as an example of what can be done. You might also find it interesting to try re-arranging the sequence order, to produce a slightly different tune (in other words, do a remix). If you wish to hear the original, the tune is a cover of a song by Metallica and its called Master Of Puppets.

Incidentally, all machine code, graphics, documentation and stuff is copyright of Boo The Ghost and Simon Forrester.

The Main Menu

This comprises the following main options:

  • Edit         Instrument
  • Manual    Channels
  • Filing       Play


There are three options on the edit menu:

  • Tune
  • Sequence
  • Timing
  • Test Sequence


This option is the main bulk of the package itself and will be entered into in more detail later.


The actual order of the sequences can be determined by using the up and down cursor keys to select the slot position, and the left and right cursor keys to select the sequence number.


Using the up and down cursor keys, the number of beats per second can be altered in the range of 1 to 10, 10 being represented by the letter A.

Test Sequence

This plays the current sequence being edited, as opposed to the entire tune.


Using the various keys (see quick keypress chart later) you may test instruments and devise tunes using this manual play option.


This deals with the loading and saving of tunes. Memory problems in making it 64k friendly, mean a catalogue option can't be included.

The Boo files can be compiled to run from BASIC, and this will be explained in more detail later on. Incidentally, facilities are present for using Boo files from machine code.


Channels may be toggled on or off by pressing the channel number. A silent channel is signified by the ghost on the particular pedestal position closing it's mouth.


This option quite obviously deals with playing your tune. Pressing ESC will return you to the main menu. It also shows up any errors in your tune - missing sequences, etc.

The Tune Editor

This is the main option and will allow you to actually compile your tune. This is done by moving the cursor over the position at which you wish to enter a note and keying that particular note. The note will then be inserted, moving all other notes forward one place. The notes are arranged in a keyboard octave, like this:

W=C# E=D#         T=F# Y=G# U=A#
A=C S=D D=E       F=F G=G H=A J=B

Cursor keys are used to move the cursor (no, really), and with CTRL depressed, the UP and DOWN keys take you to the start or end of your tune. There are several other keys that can be used in order to edit your tune with ease:

  • O - Increase octave
  • I - Use next instrument
  • L - Lower octave
  • K - Use previous instrument
  • P - Edit next sequence
  • @ - Lengthen sequence
  • : - Edit last sequence
  • ; - Shorten sequence
  • ESC - Return to editor menu
  • SPACE - Leave blank space

L'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent  du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko.
