Axiom Pro User Guide
Parameter: Program
Value Range: 0-127
This parameter sends Program Change MIDI messages on your selected Global channel and can
be used to select the different sounds contained within your sound module (or virtual instrument).
For example, if you set this parameter to “20,” your connected software or sound module will
immediately load program number 20.
Parameter: BankLSB
Value Range: 0-127
This parameter sends Bank LSB messages on your selected Global channel. In other words, a Bank
LSB message is transmitted as soon as you set this parameter to the desired number. Note that
Bank LSB messages will not have any effect until a Program Change message is sent.
Parameter: BankMSB
Value Range: 0 - 127
This parameter sends Bank MSB messages on your selected Global channel. In other words, a
Bank MSB message is transmitted as soon as you set this parameter to the desired number. Note
that Bank MSB messages will not have any effect until a Program Change message is sent.
✓ Why are BankLSB/BankMSB messages needed?
The MIDI protocol generally uses 7-bit messages to exchange
data, giving parameters a numerical data range from 0 to 127. This
explains why MIDI CC values usually range from 0-127, or why
many early MIDI modules have 128 sounds (i.e., sounds 1 through
127, plus sound number “0”).
Nowadays, many MIDI devices contain hundreds (or even
thousands) of sounds and a simple 7-bit “Program Change”
message cannot address any instruments beyond number 127. If
this is the case, the sounds are usually separated into “banks” of
128 instruments that are accessed using “Bank LSB” and “Bank
MSB” messages.
Axiom Pro can generate Program Change as well as Bank
LSB/MSB messages. However, your device must be capable of
receiving and interpreting these messages for bank changes to take
place. Please consult the user manual of your MIDI device to see
how the bank change numbers relate to the sounds on your device.
✓ NOTE: Program change commands, as
well as Bank LSB/MSB messages are
senttoallactivekeyboardzones.For
example,iftwozonesareselectedand
set to transmit on different channels,
any Program or Bank LSB/MSB
messages you generate will be sent
on both channels. This means you
mayinadvertentlyoverrideonezone’s
current program or Bank LSB/MSB
setting when trying to change the other
zone’sprogram.
Ifyouwouldlikeazonenottoreceivea
BankLSBmessage,disablethatzone
before sending the message
(disablingofzonesisdescribedinthe
“Edit Mode > Zones” section of this
guide).
