8.1 MIDI Definitions
In order to clarify some of the terminology and technology around MIDI with
respect to the T-1 a summary of key definitions is provided. T-1 uses a TRS
to Type A MIDI Adapter. Also MIDI over USB is possible.
5 PIN MIDI 5 PIN to TRS MIDI
MIDI DIN 24
This is often found for MIDI
Out and Thru and enables
syncing of classic devices.
This uses 0v & 5v messages
as sync signals at 24 pulses
per quarter note (PPQN).
MIDI CC
MIDI Control Control and
Note change messages are
used to communicate
messages across MIDI with
values of 0-127. Control
Changes (CC) affect
parameter values. T-1 can
control defined CC
assignments.
SYSEX
System Exclusive. This is an
expansion of the normal MIDI
communications set up and is
typically used for transferring
data such as back ups,
patches, presets and
firmware updates to and from
devices.
MIDI
Musical Instrument Digital
Interface. A protocol for
communicating between
electronic musical gear.
Never connect MIDI gear to
incompatible DIN signals. T-1
has USB and 5 Pin MIDI
connectivity options.
MIDI STANDARDS
While there are MIDI
standards defined, many
synth developers interpret
this in slightly different ways.
Its always worth reviewing
the documentation with each
to fully understand each
device level implementation.
SDS
Sample Dump Standard. This
is an older transfer protocol
used for transferring data to
and from devices. This is
rarely seen nowadays.
MIDI DIN 48
This is often found for MIDI
Out and Thru and enables
syncing of classic devices.
This uses 0v & 5v messages
as sync signals at 48 pulses
per quarter note (PPQN).
MSB & LSB
Most Significant Byte and
Least Significant Byte. MSB
provides the 128 data
resolution which is ok for
most MIDI applications. More
advanced devices use MSB
and LSB values increasing
resolution to 16,384 steps.
NRPN
Non-Registered Parameter
Number is part of the MIDI
standard. CC and NRPN are
technically very similar but
NRPN is less well defined in
the standards. NRPN uses
more data and can give
better control.
The term ‘primary lead’ will refer, in this guide to a device that has the main control responsibility.
For example, one which controls the clock and transport and is the central lead. It is typical for T-1
to be a primary lead. A device which will be controlled by, and will follow the primary lead device
and which will be subservient by responding to the main control messages will be called a
‘secondary follower’. A synthesizer module could be a typical secondary follower.
