System Exclusive Implementation
MIDI System Exclusive communication allows a user to control a device directly through MIDI in a very powerful and flexible manner. Much
care has gone into creating and testing this documentation but Johnson Amplification can not guarantee 100% accuracy, nor can Johnson
Amplification be held responsible for presets and data lost in a product from System Exclusive Information use.
A working knowledge of the MIDI Version 1.0 Detailed Specification can be useful while implementing any manufacturer's SysEx commands.

It is a good practice to back up any user programs and/or user algorithms in the device before you begin to work with SysEx commands due to
the fact that incorrect commands can produce unexpected results. Should you encounter any discrepancies between this documentation, and
a Johnson Amplification S-DISC II™ MIDI, product please feel free to contact us at:

MIDI Basics
MIDI Channels : The Millennium can be set so that they communicate on 1 of 16 discrete MIDI channels. Some devices may also be set
up to transmit or receive information on all channels in an Omni mode or to none of the channels in a Disabled mode.
Preset Changes : When the Millennium is set to communicate on one or all of the MIDI channels, it will recognize a Preset Change
command. If the number is legal (e.g. within the device’s range of selectable presets) the Johnson Amplification device will respond by
changing to the new preset. MIDI sends Preset Changes 0 through 127. Johnson Amplification devices begin their preset numbering with 1,
thus Preset Change 0 will select preset 1. The Millennium also allows the user to ‘re-map’ the Preset Change commands so that Preset
Change 0 could call preset 135, if so desired.
Continuous Controllers : A MIDI Continuous Controller may be ‘Linked’ to nearly any available parameter in the Millennium. CC links
(Modifiers) and their ranges are treated uniquely in each preset with the assignments being saved only if they are stored as part of the
preset.
Channel Pressure : Johnson Amplification products treat Channel Pressure as simply another type of Continuous Controller which can be
linked to parameters for control.
