Attax MIDI Option MSM1

This is the Hughes & Kettner MIDI switching module for the Attax preamp, Attax 100, Attax 200, Tubeman plus, BassBase 600, TriAmp MKII, WARP-X, Tube 50, and Tube 100. It actually installs into these units, so you don't have an extra piece of gear to gain MIDI functionality.

CONNECTIONS AND CONTROL FEATURES

1. MIDI IN JACK: The MIDI IN jack is designed to receive MIDI data. Any device capable of generating MIDI data can be connected here via its MIDI OUT jack. In most cases, a MIDI FOOT CONTROLLER or MIDI EFFECTS UNIT is the device you will use.
2 MIDI THRU JACK: The MIDI THRU jack is used if you want to relay incoming MIDI messages to an additional MIDI device, e.g. an effects processor. Simply connect the device's MIDI IN to the MSM-1 's MIDI THRU. This enables you to address the ATTAX and one or more additional devices via a single MIDI command.
3 MIDI RECEIVE CHANNEL SWITCH: This five-way DIP switch determines on which MIDI channels the MSM-1 receives MIDI messages. You can select a single CHANNEL (1 through 16), or all MIDI CHANNELS at once.
MIDI LEARN BUTTON (front panel): The MIDI LEARN BUTTON on the ATTAX front panel is operable after the MSM-1 is installed, and is used to assign ATTAX channel/effects combinations to various memory locations.

MIDI FUNCTIONS: MIDI is the abbreviation for Musical Instrument Digital Interface. MIDI is an international standard in which musical information, to include sound parameter changes, is translated to digital data and sent to various instruments, e.g. amps, effects devices, keyboards, etc. The MSM-1 can process MIDI commands containing sound changes, i.e. messages that change the ATTAX channel/effects loop settings. These commands are referred to as MIDI PROGRAM CHANGE MESSAGES. They consist of a MIDI CHANNEL NUMBER and a MIDI PROGRAM number.
MIDI CHANNEL NUMBER: A typical guitar rack can contain several MIDI capable devices. You must assign each device a specific MIDI CHANNEL NUMBER to ensure the message is addressed to the right device. 16 MIDI CHANNELS (1 through 16) are available. For instance, if you assign MIDI CHANNEL NUMBER 7 to the MSM-1 (refer to Section 2.1), then the module reacts exclusively to commands addressed to MIDI CHANNEL 7.
OMNI MODE: If you want to address several devices in your rack simultaneously, switch on the OMNI MODE for each device. All devices will then ignore the MIDI CHANNEL NUMBERS and respond to MIDI commands on all CHANNELS. Refer to Section 2.1 for information on how to select the MSM-1 OMNI MODE.
EXAMPLE: The MSM-1 is set to MIDI CHANNEL 3. A MIDI command containing a "MIDI CHANNEL 3/PROGRAM NUMBER 17" message is sent. The MSM-1 responds by activating the channel and effects loop combination saved on preset 17.
