The MIDI (Musical Instrument Interface)
is
a digital Interface
which allows
different
types
of
musical instruments (MIDI com-
patible)
to
communicate with each other.
In
ttle
case
of the ER
33,
this interface permits the transmission
of
the data
of
all
the
outstanding features
of
this
synthesizer
mo-
du
le
to
other Instruments and using the same techniques can r
e-
ceive all the neces.sary MIDI information needed
to
control these
same functions from any other M
IDI
compatible instrument.
MIDI IN M
IDI
OUT and MIDI THRU are the three sockets
by
means
~f
which
the
ER
33
can
be
connected
to
a keyboard,
se-
quencer, synthesizer
etc
., as explained in
t
~
CONNECTIONS
section, F
or
some examples of vanous M
IDI
connec-
tions,
you should consult Fig. 1 MI
DI
CONNECTION EXAMP
LES
(below).
The
ER
33
can receive
ttle
following information on the MIDI bus
(MIDI IN):
1. KEYBOARD
OAT
A (Key On I Key Off).
2.
KEY
VELOCITY SENSITMTY (Keyboard Dynamics)
3. SECOND TOUCH (Pressure used on the
keys
after the note
has been played.
~
.
PROGRAM CHANGE (changing
of
the PRESET number).
5. MODULATION CONTROL
('WHEEL
, MODULATION, SE-
COND TOUCH).
6. PEDAL EFFECTS (Volume Pedal, Sustain Pedal, Portamento
Peda
l).
7. SYSTEM EXCLUSIVE

N.B. H
the
unit connected to
the
ER
33
does
not
provide all these
fu
nctions, then the ER
33
will only be concerned with the data
transmitted from
that
unit. For example,
If
the
Instrument
does
not
provide for dynamic control, then
the
ER
33
will n
ot
be
able
to
have this function. When
the
SYSTEM EXCLUSIVE
is
activa-
t
ed,
the
connecting
of
two
ElKA Instruments
(EK
44 - E
K22
-
ER33-
EM44-
EM22) will
also
permit
the
n
umber
of
the
PER-
FORMANCE REGISTRATIONS
to
be transmitted.
By
means
of
SYSTEM
EXC
LUSIVE
it
is
possible to transm
it
and receive from
a computer,
all t
he
lnfoonation regarding the ER
33
(PARAME-
TERS. MULTISPUT, MI
DI
CHANNELS. PERFORMANCE
REGI
-
STRATIONS,
ET
C.).
The ER
33
transmits
the
following M
IDI
data (MIDI OUT):
1.
PROGRAM
CHANGE
2. PEDAL
EFFECTS
3. SYSTEM EXCLUSIVE
To connect
the
ER
33
to
another MIDI instrument you must use
a
MIDI DIN Standard connecting cable, remembering the gene-
ral rule
that
two
instruments can receive
or
transmit from and
to
one
another only
if
the
same
MIDI channel
has
been selected.
N.B.
USE
ONLY 3-
PIN MIOI CONN
ECTI
NG CABLES.
