   Quad sound looks like a compromise with
additional musical coprocessor
rum At the same time, the composer receives
disposal of 6 independent musical
channels instead of three!                   
   The proposed quad system contains
two additional ports with addresses
#AFFD (45O53) and #EFFD (61437) for
connecting additional music
coprocessor.                           
   Port #AFFD corresponds to performance
our functions to the same port #BFFD, and
port #EFFD - port #FFFD.               
   In such a system it remains compatible

AU melodies, i.e. previously written me-

in quad music, the sound will also appear
in the side columns.

   The advantages of this system are obvious.
With a slight increase in the occupied
melody of memory (maximum twice as much
conventional) and economical use of ma-
bus time, sound quality has become
soars much higher.                     
   To remake any melody to the second
swarm coprocessor, just change
port values in PLAYER.             
   At this stage there is no complete
valuable music editor for 6 channels,
but the application includes a program
"QUADRA CONVERTER", which allows
remake music from regular AU to
additional.                         
   Playing two melodies in parallel,
QUADRA and regular, you can get six-
channel sound.                     
   Of course, this way of making music
inconvenient, but if this development is
receives support, it will be possible to talk about
writing by QUADRA MUSIC EDITOR.
