the port on a device that transmits the MIDI data generated by
the device.
the port on a device that passes received MIDI data to the next
device in the chain.
a performance mode where two or more Programs are played at
the same time. Mix mode is where you make settings for splits
and layers plus numerous combinations of Programs, and
keyboard/MIDI control.
a particular state that an instrument or device is currently in;
in MIDI, "mode" refers to the unit's receive state that determines
1. how MIDI messages are received, and 2. how voices will be
assigned to handle MIDI notes.
a general term that indicates that a pressed key on the local
keyboard has been let go, a MIDI Note Off message has been
received, or the end of the Gate Time from the Sequencer or
Arpeggiator has been reached.
a general term that indicates that a key has been pressed on the
A6's keyboard, a MIDI Note On message has been received, or
notes are being played from the A6's Arpeggiator or Sequencer.
a receive function that instructs the device to respond to
commands on a specific, user-selected Channel.
a receive function that instructs the device to respond to
commands on any Channel.
a group of related parameters on the display.
a basic element of an A6 function.
the settings that cause the voices to produce a particular sound.
a command that instructs the receiving instrument to recall a
specific sound program from memory.
"Random Access Memory": the physical circuit chips inside the
A6 where data is stored. RAM is a type of memory that you can
change and is also referred to as user memory.
"Read Only Memory": the physical circuit chips inside the A6
where data is stored. ROM is a type of memory that is
permanent and is also referred to as preset memory.
"System Exclusive"; data that is unique to a particular MIDI
device.
data that is transmitted to all devices in a MIDI system; this data
is not Channel-specific.
a data stream that synchronizes MIDI devices, such as a
sequencer or drum machine.
a "go" signal that is routed from a source (such as the keyboard)
to a modulation function. A trigger has no significant duration
as it is simply an electronic pulse. Translating our definition of
trigger to MIDI, a trigger is the equivalent of a Note On
command. See also "Gate".
the most basic component of a synthesizer that produces sound.
A voice is all of the hardware and software that is necessary to
produce one note of sound.
