ONTROLLERS
The M
IDI
messages transmitted and received by the S Series (and by the more
recent M
IDI
instruments) are:
N
OTE
: Note data, consisting of four values: note name, velocity on, velocity
off, gate (note duration).
P
ITCH
B
END
: Lowering or highering of the pitch, sent by a dedicated controller
(e.g. a Wheel).
M
ONO
T
OUCH
(or Channel Pressure): Pressure applied to a key after playing
the note (key on). Applying pressure to one note affects all the notes of the
same Midi channel.
Poly Touch (or Poly Pressure): Pressure applied to a key after playing the
note (key on). Applies to the note playing and does not affect other notes
being played. It consists of two values: note on which the pressure is applied,
the intensity of the pressure applied.
Program Change: Sound selecting data.
Control Change: Various messages which control single Sound parameters
(volume, pan) or the overall setting of the instrument (All note off, Omni mode
on, Reset).
A Control Change message activates a M
IDI
Controller, a series of software
controls of the sound. The Control Change message consists of two numeri-
cal parts: (n1) the number which determines the activation of the Midi
Controller, (n2) the value of the M
IDI
Controller:
Control Change, n1, n2
The following table lists all the Midi Controllers in numerical order. Next to
the decimal number of the Controller is the name of the function that is
controlled. Controllers 0 … 31 are “continuous” controls, which affect a
parameter for the duration that they are applied. Controllers 64 … 127 are
“switch action” controllers, which remain active until the Controller is
applied again.
Controllers 32 … 63 are the LSB (Least Significant Byte) part of the message
transmitted by the Controllers 0 … 31 (which are the part MSB (Most
significant Byte). The coupling between the MSB and LSB takes place
without user intervention.
Some Midi Controllers, coded as “unused” in the Midi protocol standard,
have been utilized by the S Series as specific controllers which permit the
modification via Midi of some of the S Series Sound parameters (Attack,
Release, Filters, Effects). The function implemented in the S Series is shown
in square brackets [ ].
Messages shown in grey affect the S Series sound generation. Messages
identified by an asterisk (*) travel on the Midi-Comon Out channel and not
on the channel assigned to the track.
