of connecting to a computer without having to connect two sets of standard MIDI cable. The information
that flows through the USB connection conforms to the same Message format as standard MIDI.
Since MIDI information flows in one direction only along a standard MIDI cable, it is not possible to have a
MIDI In socket connected to another MIDI In socket. For example, if this were done the MIDI network
would simply not work ! In fact, the only routings allowed are MIDI Out to MIDI In or MIDI Thru to MIDI In.

Keyboard Controllers such as the ReMOTE 25 are used exclusively to generate MIDI data for controlling
other instruments. Examples of other common MIDI controllers are drum percussion pads or footswitch
controllers.

MIDI Messages
The ReMote 25 is capable of transmitting various types of MIDI events. These are as follows :
Note Messages
A note message is transmitted every time a key on the ReMOTE 25’s 25 note keyboard is pressed down
or released. When a keyboard note is pressed down, the MIDI message also includes velocity information.
This represents how hard the key was pressed down. This velocity value can be used to add dynamics to
the sound, depending on how hard the note was played.

This represents how hard the key was pressed down. This velocity value can be used to add dynamics to

It is also possible to configure buttons on the front panel to transmit Note messages such that a Note On
message is sent when the button is pressed and the corresponding Note Off message sent when the but-
ton is released. This is detailed on page 33.

Control Change Messages
These messages are commonly used to alter synthesizer parameters by MIDI. In many of the Preset
Templates, it is actually Control Change messages which are sent when the front panel controls are
moved.

The MIDI specification allows for 128 different types of controller message. These are often referred to as
Continuous Controllers (CC0 to CC127).
Continuous Controllers (CC0 to CC127).
Some controllers are rigidly defined by the MIDI standard for specific functions. For example, CC1 is
always used for the modulation wheel. Therefore, whenever you move the ReMOTE 25’s modulation joy-
stick, it will transmit MIDI control change information using CC1. All makes of synthesizers will also use
CC1 for modulation wheel data.

Another example is the ReMOTE 25’s footswitch. In the Preset Templates, this will always transmit using
CC64 which is universally accepted across all MIDI instruments for sustain pedal operations.

The Continuous Controller numbers rigidly defined include 0, 6, 32, 38, 96. 97, 98, 99, 100, 101 & 120 -

Many Control Change numbers have no set purpose within the MIDI specification. For example, whenever
a Novation K-Station’s Filter FREQUENCY knob is moved, it will transmit using CC109. There is no guar-
antee however that other makes of synthesizer will use this control change number for the same purpose.

A CC MIDI message can contain a data value anywhere in the range 0 to 127.
Use of Control Change messages is detailed on pages 28 to 30 .
