These messages are specified as arguments to a midievent message, which triggers the notes in the VST instrument.

The following table outlines some common MIDI messages and their functions:

MIDI Message	Function
Note On	Initiates a note
Note Off	Stops a note
Control Change	Adjusts parameters like volume
Pitch Bend	Modifies pitch smoothly

To properly format MIDI messages for VST instruments, the midiparse and midiformatobjects in Max assist in converting raw MIDI input into structured messages (Cycling '74).

Control Change Messages

Control change messages (CC messages) play a vital role in modulating VST instrument parameters. These messages are formatted as lists where the first value is the controller number, and the second value represents the controller value. Some standard control change numbers and their functions are listed below:

Control Number	Function
64	Sustain Pedal
7	Volume Control
1	Modulation Wheel
10	Pan Position

For example, a control change message for the sustain pedal, such as 64 127, will sustain the notes played. Similarly, 7 100 would set the instrument's volume level to a value corresponding to 100.

Advanced manipulation of MIDI messages can be achieved using the midiformat object in Max, which allows for high-resolution pitch bend control by setting the @highres attribute. This enables fine-tuning of pitch bend values ranging from -8192 to 8191, providing 16384 possible positions for pitch modulation (Cycling '74).

By mastering MIDI messages and control change commands, users can harness the full potential of VST instruments, opening up endless possibilities for musical creativity and expression.
