In thousands of music learning systems across the country, group instruction has proven to be an exceptionally practical and productive method for teaching music. The heart of our group learning systems is a fully digital, flexible and cost effective central routing system - the Korg Group Education Controller 3, or GEC3. Suitable for any teaching level and any combination of electronic instruments, (MIDI keyboards, guitars, sound modules, computer sound cards, etc.) the GEC3 allows teachers to interact with as many as 32 different student stations (up to 64 students, since each student station accommodates 2 students!). The GEC3 offers the following features:

• Fully digital design throughout, featuring digital transfer of audio from each student station to the GEC3 unit, S/PDIF output for digital recording of any workstation in the system, and conventional analog inputs and outputs.
• Large, intuitive 240 x 320 Touchscreen user interface popularized by the Korg Triton Keyboard featuring easy to use tabs and screens.
• Customizable teacher and class setups, including individual teacher preferences and class set-ups displaying student names.
• Split function that allows 2 students to ­independently work on the same MIDI keyboard (profiles available for most current Korg keyboards) allowing you to more effectively teach larger groups of students with fewer keyboards.
• MIDI feature allows teacher remote control of student keyboards via conventional MIDI cables.
• Smart media source that allows you to store or backup teacher and class information and load MIDI settings for our most popular lab keyboards.
• Your class and student lists can be created using the QWERTY keypad on the touch screen or by using the USB remote control from a personal computer (Windows 98, 2000). All touch screen functions of the GEC3 can be duplicated remotely from a PC Information can be backed up on your computer or on inexpensive “Smart Media” if a computer is not available.

The GEC3 system has two major components, the GEC3 (Teacher Unit) and the Student Interface Units (SI Units). The SI Units are each connected to audio sources like MIDI keyboards, guitars, sound modules, and computer sound cards. The SI Units also have jacks for 2 student headsets (stereo headphones with microphones). All of these audio sources are combined in the SI Unit, digitized and sent to the GEC3 Teacher Unit. These connections allow the students to musically interact with one another and you in nearly any imaginable way.

An Expansion Unit (GECEXP) may be added on to the system to provide support for up to thirty two student interface connections.

There are three main modes of GEC operation. Each of these can be selected from buttons to the right of the Touchscreen interface. They include:

• Lecture Mode: This mode is used if you want to present material in a lecture format. All students hear your microphone and instrument as well as their own instruments.
• Practice Mode: This mode is used if the students are working independently. Each student hears only their own instrument. You have the option of “eavesdropping” on the student and, if you wish, initiate 2 way communication with the student.
• Group Mode: This mode is similar to Practice Mode but can be used if the students are working together in groups (two or more student workstations in any conceivable order). The students in a group can hear their own instruments as well as the instruments of the other members of their group.

• A COMPLETELY digital, microprocessor based unit – allowing completely flexible 2 way communication between students and teacher. Always digital, no noise.
• Utilizes the same touch screen panel as the Korg Triton, and many of the same design conventions in software: pull down menus, check boxes, and radio buttons. The GEC3 is easy to learn and use.
