ADD-ONE GLOBAL DATA FORMAT
The qlobal data
of the
ADD-one comprise
10
tracking generators
and
17
byteffor
the
audio trigger data
(8
thresholds,
8
mask times and
1
audio
trigger on/off). The
10
tracking generators are sent
via MIDI
as
a
block
of 180
bytes. Two bytes represent
a
point
of
a
packing
generator.
In
all
there are
9
points per tracking generator;
for
a
total
of 10

are sent

data format, the first byte
of
each point
contains ?he
7
LSB'I (least significant
bit) of the
point and
the
second

the
MSB's
(most
significant
bit) of the point
in

Bits 1-6
of the
second byte
of
each point are not used
The first

Audio trigger information

ADD-ONE CHAIN DATA FORMAT
The chain
information
is
sent via MIDI
as
a
block
of
12*

bytes
Each byte
represents
one.
step
in
the chain. As the
value
of
each step can range
between
and
127,
each step
is
sent via MIDI
as
7-bit data. Steps are
sent sequentially from
to 127.
