Using the USB terminal on your computer
with a USB/MIDI interface (UX256/UX96/
UX16, etc.)
Connect the UX256/UX96/UX16 and the computer with a
USB cable. Install the included UX256/UX96/UX16 driver
to the computer, and connect the UX256/UX96/UX16 to
the PF-1000 with a MIDI cable. Set the HOST SELECT
switch on the PF-1000 to “MIDI.” For details, refer to the
owner’s manual of the UX256/UX96/UX16.
For details about the necessary MIDI settings for computer
and sequence software you are using, refer to the relevant
owner’s manuals.
What’s MIDI?
Let’s consider an acoustic piano and a classical guitar as
representative acoustic instruments. With the piano, you
strike a key, and a hammer inside hits some strings and
plays a note. With the guitar, you directly pluck a string
and the note sounds.
But how does a digital instrument go about playing a
note?
As shown in the illustration above, in an electronic
instrument, the sampled note (previously recorded note)
stored in the
tone generator section
(electronic circuit) is
played based on information received from the keyboard,
and output through the speakers.
Now let’s examine what happens when we play back a
recording. When you playback a music CD (for example,
a solo piano recording), you’re hearing the actual sound
(vibrations in air) of the acoustic instrument. This is called
audio data, to distinguish it from MIDI data.
In the above example, the actual acoustic sounds of the
pianist’s performance are captured in the recording as
audio data, and this is recorded to CD. When you play
back that CD on your audio system, you can hear the
actual piano performance. The piano itself is not
necessary, since the recording contains the actual sounds
of the piano, and your speakers reproduce them.
