MIDI Channels & Real-time Controls

The MIDI real-time controllers may seem confusing at first, but they are really very

simple once you understand them. You probably 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 VX which note was played, can also send aftertouch 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 controller knobs, pitch wheels or touchstrips, modulation wheels, control pedals

and aftertouch. These are used to add more expression or control.

The controller knobs send out real-time controller information on separate continuous

controller numbers. There is a set of 128 continuous controller numbers for each MIDI

channel. Some continuous controllers, such as modulation wheel, volume, and pan

have standardized numbers. For example, volume is usually sent on continuous

controller #7. The controller knobs are programmed to specific MIDI controls.

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 real-time

controller numbers that the keyboard transmits must match the numbers Proteus VX 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 VX

can handle up to 16 MIDI controllers (A-P) of your choosing. “MIDI A-P” are simply

names for the internal connections that link external MIDI continuous controllers to

the Cords page. There are two parts to the connection. First, MIDI controller numbers

are assigned to the letters A-P in the Controllers dialog box. Next, the letters A-P are

connected to synthesizer control parameters in the PatchCord section of the Preset Edit

window. The Cord Amount scales the amount of each controller by a positive or

negative value.

Most factory presets have the MIDI A-P controls connected to standard synthesizer

functions (labelled in the Multisetup page). By choosing any four of the 16 standard

functions, the four sliders on your keyboard will work the same on every preset. The

chart on the following page shows how this might work if your keyboard transmitted

the slider settings on MIDI controllers 21-24.
