-
- One of the most exciting aspects of
-
- the new Commodore 128 is its musical
-
- ability. The 128 uses six keywords
-
- to facilitate working with sound.
-
- They are:
-
- VOL SOUND PLAY TEMPO
-
- ENVELOPE FILTER
-
- By using the simple commands, plus
-
- some creative thinking, you could
-
- become the Amadeus of the electronic
-
- age.
-
- VOL is short for Volume. The
-
- higher the volume, the louder the
-
- sound. SOUND produces tones and
-
- other simple sound effects with a
-
- minimum of programming effort. PLAY
-
- and TEMPO are used to make song
-
- playing easier. They are usually
-
- used for more complex sounds than is
-
- SOUND. The last two, ENVELOPE and
-
- FILTER are used to dramatically
-
- change the nature of the tones
-
- produced with the other statements.
-
- When used together, these six simple
-
- statements open up the doorway to
-
- wonderful music and sound on the
-
- Commodore 128.
-
- There are five programs on this
-
- issue of LOADSTAR. They each teach a
-
- different lesson of music creation on
-
- the 128.
-
- The first program, TEST TONE.128,
-
- is used to adjust your speaker to a
-
- comfortable listening level. A tone
-
- is played at medium volume. You
-
- should then adjust the volume control
-
- on your monitor or TV.
-
- The next three programs,
-
- (SOUND1.128, SOUND2.128, and
-
- SOUND3,128) let you hear the
-
- different frequencies (tones) that
-
- can be produced as well as how these
-
- tones sound when used with more than
-
- one voice.
-
- The last program, PLAY1.128, is by
-
- far the most advanced. It first lets
-
- you hear some notes at different
-
- volume levels. Next, it will sound
-
- the range of frequencies that can be
-
- produced on the 128. The program
-
- will then allow you to listen to some
-
- selected tempos. The next step in
-
- the program will let you hear the
-
- pre-set envelope settings of the 128.
-
- Lastly, the program finishes with a
-
- bit of fanfare.
-
-
- **** NOTE ****
- Because these programs are written
- for the Commodore 128, you cannot RUN
- them from the LOADSTAR environment.
- All of the above programs are on
- Side one of this issue of LOADSTAR.
- To make it a bit easier to find them,
- they all have the suffix '.128'.

-
- you from the burden of keying in this
-
- program. For more complete
