MIDI AND USB
MIDI stands for Musical Instrument Digital Interface. This is a world-wide standard com-
munication interface that enables electronic musical instruments and computers (of all
brands) to communicate with each other so that instructions and other data can pass
between them. This exchange of information makes it possible to create a system of MIDI
instruments and devices that offer far greater versatility and control than is available with
isolated instruments. Whether you interface with computers, sequencers, expanders or
other controllers, your musical horizons will be greatly enhanced.
MIDI CONNECTION
The USB connector allows you to
connect the Overture directly to your
computer. It can be connected without
driver installation under the Windows
XP, Vista & Mac OSX environments.
MIDI IN:
This terminal receives MIDI data
from an external MIDI device.
MIDI OUT:
This terminal transmits data
from this instrument to other MIDI
devices. The transmitted data include
the notes, touch velocity and pedals
actions produced while playing on the
piano, as wellas voice changes.
USB CONNECTION
The Overture will be recognized as
a “USB Audio device” to receive and
transmit MIDI messages through a
single USB cable (MIDI In/Out via
USB).
LOCAL MODE
From a MIDI point of view, the Overture is composed of two “devices”:
● A controller transmitting data (the keyboard and pedals)
● A sound generator receiving MIDI data (the sound module)
In normal operation (Local ON, default
mode), those two devices are con-
nected together internally, allowing the
keyboard to play voices from the sound
module without any external connec-
tion. When Local mode is OFF, this
internal link is disconnected. The sound
module receives MIDI messages via
MIDI input only, not from the keyboard.
However, the keyboard performance
data is still sent to the MIDI Output.
Local OFF mode is intended to be used
when both the MIDI input and output (or
the USB port) of the Overture are con-
nected to a MIDI sequencer with a Soft
Thru function.
