Proteus operation manual MIDI Realtime Controllers
Common realtime controllers such as the pitch wheel, volume, pan and
pressure are pre-programmed to their proper destinations. Your key-
board may have other realtime controls such as a control pedal or data
slider which can also be programmed to control most of the parameters
on Proteus.
The Proteus is equipped with a sophisticated MidiPatch
™
system , which
allows you to route any continuous controller to any realtime modulation
destination. The MidiPatch system is also very easy to use. First, you
must know which controller numbers your keyboard can transmit.
MIDI REALTIME CONTROLS
The MIDI realtime controllers may seem confusing at first, but they are
really very simple to understand. You probably already know that there
are 16 MIDI channels that can be used. Each of the 16 MIDI channels uses
basically 3 types of messages;
note on/off , program changes , and continuous
controller messages.Your MIDI keyboard, in addition to telling Proteus
which note was played, may also send realtime control information, which
simply means occuring in real time or live. (You may be using a MIDI
device other than a keyboard, but for simplicity's sake we'll presume that
you're using a keyboard.) Realtime control sources include such things as
pitch wheels or levers, modulation wheels or levers, control pedals,
aftertouch, etc. and are used to add more expression or control. Your
MIDI keyboard sends out realtime controller information on separate
channels called
continuous controller channels . There is a set of 32 continu-
ous controller channels for each of the 16 MIDI channels. Some of the
controller channels, such as pitch wheel, volume, and pan have been
standardized. For example, volume is usually sent on continuous control-
ler channel #7.

MIDI wind controllers
may work better if you
assign one of the MIDI
A, B, C, D controllers to
control volume. This will
allow the MIDI volume
to be
added to the
current volume.
