Black Magic Composer8

- 10: Sinewaves. Voice 0+2 are combined into a single sound register. Two very high frequency notes

are combined to give one tone in a sine wave. This method is not very exact and will make most

notes sound detuned.

- 11: Sinewaves, with double the frequency. This option theorethically expands the sinewave output

scale to 4 octaves!

- 13: Sawtooth waves. The same notes apply as for the Sinewaves.

- 12: Sawtooth waves, with double the frequency.

Important: Whenever two voices are combined, they both have to play the same notes at the same

time!

The envelope (output strength, volume) of the instrument can be edited on the lower right side of the

editor screen. The top value is the volume, the lower one is the distortion. (See the Atari Basic

manual!) The values can be changed with the keyboard, or in the graphical representation with the

mouse.

Each instrument table is a maximum of 128 entries long, and can be scrolled with the scrollbar below.

There is a red and a green marker in the instrument definition. The first marks the end of the

instrument, the other marks the entrypoint where the instrument loops to when it's played longer than

the defined length. Setting these markers is possible by pressing "<" and ">".

Arpeggios are entered in the lower left part of this editor. These 4 entries show transpose values to

rapidly change the pitch of the tone. Entering 00 four times, will not change the note. Values like

00/03/07/0C will rapidly arpeggiate though one octave. (This sounds a bit complicated but can sound

pretty darn well!) If you'd like to use an arpeggio with less values, the remaining, unused values

should be set to 80.

Setting the instrument number, aswell as the copy function, work the same as in the sequence editor.

10 Playing music

Logically, clicking the "PLAY"-icon opens up the player.

The 4 bars above show the current volume of the voices. The buttons look and function like a casette

player, with the exception of the "eject"-button, which is used to initialise the song. (Use this after disk

operations, or any change in the song, or you'll suffer distortions during playback.) If the song uses

digitised sounds, you will not be able to move the mouse-cursor. It will switch to the "stop" position

though, so a single click will stop the music, relinquishing control back to the joystick/mouse. Spooling
