Connecting External Devices

Connections to a Computer
You can use a USB connector to connect the HPi-7 to your
computer.
Roland’s “Visual MT” is installed, you will be able to play the sound
of the software sound generator from the HPi-7’s speakers, or save a
recorded HPi-7 song on your computer.
For more details, refer to the separate “USB Installation
Guide.”

* To prevent malfunction and/or damage to speakers or other
devices, always turn down the volume, and turn off the power on
all devices before making any connections.
* Connecting your computer to the HPi-7 for the first time requires
installation of the “USB Driver” (on the included CD-ROM) to the
computer. For more details, refer to the separate “USB
Installation Guide.”
* Only MIDI data can be transmitted using USB.
* Use a USB cable no longer than 3 meters.
* USB cables are not included. Consult your Roland dealer if you
need to purchase.
* Turn on the power to the HPi-7 before starting up MIDI
applications on the computer. Do not turn the HPi-7 on or off
while any MIDI application is running.
* Do not connect or disconnect the USB cable while the HPi-7’s
power is on.
* If not using USB, disconnect the USB cable from the HPi-7.
* If, during the transmission/reception of data, the computer
switches to energy-saving mode or suspended mode, or if the
HPi-7’s power is switched on or off, the computer may freeze, or
the HPi-7’s operation may become unstable.
* When using your computer’s sequencer software to record
HPi-7 performances, we recommend setting the sequencer
software’s Soft Thru to “OFF.”

MIDI settings

MIDI transmit channel setting

MIDI has sixteen “MIDI channels,” numbered 1–16. Even if a MIDI
device is connected, it will not be possible to play or select sounds
unless the MIDI channels of the two devices match.
* When Dual performance (p. 27) is being used on the HPi-7, only
the channel you specify here will be transmitted.
* The HPi-7 receives all channels 1–16.

Local Control setting

If the data that is produced when you play the keyboard is sent to
the sound generation section via both routes (1) and (2) as shown in
the diagram, notes will be doubled or may be interrupted. To
prevent this, use the “Local Off” setting to disconnect route (1).
Set Local Off if you have connected the HPi-7 to a MIDI sequencer.

* When a Roland MT series instrument is connected, it is not
necessary to make the Local Off setting. The MT transmits a
Local Off message when the power is turned on. If you turn on
the power in the order of the HPi-7
→
MT series, Local Off will be
set automatically.
