The MIDI real-time controllers may seem confusing at first, but they are
really very simple once you understand them. You already know that there
are 16 MIDI channels per MIDI cable. Each MIDI channel uses three basic
types of messages; note on/off, preset changes, and continuous controller
messages. Your MIDI keyboard, in addition to telling Proteus 1000 which
note was played, can also send real-time control information, which simply
means control occurring 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 are using a keyboard.) Real-time control sources include such things as
pitch wheels or levers, modulation wheels or levers, control pedals and
aftertouch and are used to add more expression or control.
Your MIDI keyboard sends out real-time controller information on separate
continuous controller numbers. There is a set of 32 continuous controller
numbers for each MIDI channel. Some of the controllers, such as the
modulation wheel, volume, and pan have standardized numbers. For
example, volume is usually sent on continuous controller #7. Your
keyboard may have other real-time controls such as a control pedal or data
sliders which can also be programmed to control the Proteus 1000.

The following MIDI
controls are automatically routed
in Proteus 1000:
Pitch Wheel pwh
Modulation Wheel 01
Old DX7 Aftertouch 03
Pedal 04
Volume 07
Pan 10
Expression 11
Any MIDI controller can be routed to any modulation destination. First,
you have to know which controller numbers your keyboard transmits. Most
modern MIDI keyboards let you select a controller number for each control
on the keyboard. For example, it may let you select a number from 0-31 for
the data slider. The realtime controller numbers that the keyboard
transmits must match the numbers Proteus 1000 is receiving, otherwise
nothing will happen when you move the controls.
Suppose you wanted to send the four data sliders on your master keyboard.
Proteus 1000 can handle 12 MIDI controllers (A-L) of your choosing. “MIDI
A-L” are simply names for the internal connections that link external MIDI
continuous controllers to the PatchCord section of Proteus 1000. There are
two parts to the connection. First, MIDI controller numbers are assigned to
the letters A-L in the Master menu. Next, the letters A-L are connected to
synthesizer control parameters in the PatchCord section of the Edit menu.
The PatchCord Amount scales the amount of each controller by a positive
or negative value.
