When MIDI cables are used to connect two or more MIDI devices, performance data can be exchanged between the devices, even if they were made by different manufacturers. A USB cable can be used to connect the Grandstage to a personal computer. See “Connecting the Grandstage to your computer via USB” on page 5. Connecting the Grandstage to a MIDI device or computer The MIDI connectors of the Grandstage can be connected to the MIDI connectors of an external device to exchange MIDI information. Note: To exchange data, you will need to set the MIDI channels on the transmitting and receiving end to the same channel. MIDI IN connector The Grandstage receives MIDI messages via the MIDI IN connector, from the MIDI OUT connector of an external device when connected. MIDI OUT connector The Grandstage sends MIDI messages via the MIDI OUT connector, to the MIDI IN connector of an external device when connected. 2 Controlling an external MIDI tone generator from the Grandstage When you want to use the Grandstage’s keyboard and controllers etc. to play an external MIDI tone generator, use a MIDI cable to connect the Grandstage’s MIDI OUT connector to the MIDI IN connector of the external MIDI tone generator. MIDI IN MIDI OUT External MIDI tone generator Grandstage 88/73 Tip: The Grandstage can also control an external MIDI source using its split function, by transmitting messages on two separate MIDI channels, one for the upper part (higher note range) and one for the lower part (lower note range). Refer to “MIDI channel setting (MIDI Channel)” on page 6, “MIDI Ch Mode (MIDI channel mode)” on page 6 and “MIDI Ch (Lower) settings (MIDI channel for the lower part)” on page 7 for how to configure the settings. Controlling the Grandstage’s tone generator from an external MIDI device When you want to play or control the Grandstage’s tone generator from an external MIDI keyboard or sequencer etc., use a MIDI cable to connect the MIDI OUT connector of the external MIDI device to the MIDI IN connector of the Grandstage. MIDI OUT MIDI IN MIDI keyboard Grandstage 88/73 3 Connecting an external MIDI sequencer or computer etc. If you want to record your performance on the Grandstage’s keyboard into your external MIDI sequencer/computer (via a MIDI interface), or use the Grandstage as a combination of controller keyboard and MIDI sound module, or use the Editor/Librarian software included with the Grandstage, then you’ll need to connect the Grandstage’s MIDI OUT and MIDI IN connectors to the MIDI IN and MIDI OUT connectors respectively of your external MIDI sequencer or computer. Tip: It’s convenient to use the USB port when connecting the Grandstage to your computer. MIDI OUT MIDI IN MIDI interface MIDI IN MIDI OUT Computer Grandstage 88/73 Tip: The KEYBOARDS and ENSEMBLE sections can be set to separate MIDI channels. You can connect an external MIDI sequencer or a computer to the Grandstage to control the Grandstage’s two separate sound generators. Refer to “MIDI channel setting (MIDI Channel)” on page 6, “MIDI Ch Mode (MIDI channel mode)” on page 6 and “MIDI Ch (Lower) settings (MIDI channel for the lower part)” on page 7 for how to configure the settings. 4 Connecting the Grandstage to your computer via USB In order to use a USB connection, you must install the Korg USB-MIDI driver on your computer. Download the Korg USB-MIDI driver from the Korg website, and install it as directed by the accompanying documentation. Note: The Grandstage is compatible with USB 2.0 devices. USB A port USB storage devices such as USB flash drives can be connected. USB B port Connect this port to the USB A port on a Windows PC or Mac to exchange MIDI message data. USB cable USB B Computer Grandstage 88/73 5 MIDI-related settings MIDI channel setting (MIDI Channel) In order to exchange data with a connected external MIDI device, you must set the Grandstage’s MIDI channel to match the MIDI channel of the external MIDI device. Set the MIDI channel using the steps below. Setting the Grandstage’s MIDI channel 1 Press the SYSTEM button. The SYSTEM button will blink, and the word “SYSTEM” will show on the top line of the KEYBOARDS section display. 2 Select the “MIDI Channel” parameter on the second line of the display with the VARIATION knob. 3 Set the channel using the LEVEL knob in the KEYBOARDS section. 4 After you are finished with the settings, press the SYSTEM button or the EXIT button. The SYSTEM button will go dark. MIDI Ch Mode (MIDI channel mode) This selects the MIDI channel mode used by the Grandstage to transmit and receive MIDI data. Global Only: Uses only the channels set in “MIDI Channel”. When playing in layered or split mode, this keyboard will transmit and receive on only one channel. U/L Individual (Upper/Lower Individual): The channels set using the “MIDI Channel” and “MIDI Ch (Lower)” settings will be used to transmit and receive MIDI data for the KEYBOARDS and ENSEMBLE sections. (The default channels are 1 and 2 respectively.) Select this if you want to control external MIDI devices in split mode via different MIDI channels, or if you want to play the two layered sounds of the Grandstage from an external MIDI device via different MIDI channels. Normally, this is set to “Global Only”. The default setting is “Global Only”. 1 Press the SYSTEM button. The SYSTEM button will blink, and the word “SYSTEM” will show on the top line of the KEYBOARDS section display. 2 Select the “MIDI Ch Mode” parameter on the second line of the display with the VARIATION knob. 3 Use the LEVEL knob in the KEYBOARDS section to set this to either “Global Only” or “U/L Individual”. 4 After you are finished with the settings, press the SYSTEM button or the EXIT button. The SYSTEM button will go dark. 6 MIDI Ch (Lower) settings (MIDI channel for the lower part) This setting is enabled when the MIDI Ch Mode is set to “U/L Individual”. This specifies the MIDI channels on which the Grandstage will transmit and receive for the lower ENSEMBLE section note range (normally, this is the lower part). Note: The MIDI channels for the KEYBOARDS section are set using “MIDI Channel” (normally, this is the upper part). On the Grandstage, different MIDI channels can be set for the KEYBOARDS section (usually the upper part of the keyboard) and the ENSEMBLE section (usually the lower part of the keyboard), to play an external MIDI device at the same time as the Grandstage’s keyboard; or to connect to an external MIDI sequencer in order to control the Grandstage’s keyboard as a multi-timbral sound generator. Refer to “MIDI Ch Mode (MIDI channel mode)” on page 6. 1 Press the SYSTEM button. The SYSTEM button will blink, and the word “SYSTEM” will show on the top line of the KEYBOARDS section display. 2 Select the “MIDI Ch (Lower)” parameter on the second line of the display with the VARIATION knob. 3 Set the channel using the LEVEL knob in the KEYBOARDS section. 4 After you are finished with the settings, press the SYSTEM button or the EXIT button. The SYSTEM button will go dark. MIDI “LOCAL” setting when connecting an external MIDI sequencer or computer If notes are sounding doubled when the Grandstage is connected to an external MIDI sequencer or computer, turn the Local setting off. If the Grandstage is connected to an external MIDI sequencer or computer, and the Echo Back setting of the external MIDI sequencer or computer is turned on while the Grandstage’s Local Control setting is also on, the performance data that’s generated when you play the Grandstage’s keyboard will be sent to the external MIDI sequencer, and will also be echoed-back to sound the Grandstage’s tone generator a second time. To prevent each note from being sounded twice, once directly from the keyboard and once from the echoed-back note, you must turn the Grandstage’s Local Control setting off (SYSTEM - Local Control). Setting the MIDI local control on the Grandstage 1 Press the SYSTEM button. The SYSTEM button will blink, and the word “SYSTEM” will show on the top line of the KEYBOARDS section display. 2 Select the “Local Control” parameter on the second line of the display with the VARIATION knob. 3 Set the value to “Off” using the LEVEL knob in the KEYBOARDS section. 4 After you are finished with the settings, press the SYSTEM button or the EXIT button.
