Getting Started
The PXR4 is a digital multi-track recorder that uses SmartMedia™ as its recording and storage medium. A
SmartMedia™ card must be inserted in order to record and playback audio data on the PXR4, and can provide you
with up to TWO HOURS of recording time. You can record from any external source, including acoustic instruments
and vocals (with the built-in condenser microphone). Once you’ve recorded songs, you can transfer them to your
computer (Mac or PC) for backup and editing, using the built in USB (Universal Serial Bus, cable not included). The
included card contains two demo songs. You can use these songs to learn the mixing, effects and other functions in
the PXR4, and then erase the data on the card for use with your own projects.
PXR4 EasyStart
Install the SmartMedia card:
- Make sure that the power is OFF before inserting or removing a SmartMedia card.
- When using a store-bought SmartMedia™ card, you must format it first on the PXR4.
Open the card slot cover by sliding it away from the bottom of the unit, allowing the hinge to fall open, and
then insert the card with its contacts facing the bottom of the PXR4, then push the card all the way into the
slot until it locks into place. (To remove the card, push the card into the slot to unlock it, and then pull it out)
Make connections:
Connect the included AC adaptor to the jack on the rear panel.
Connect a guitar or bass to the GUITAR INPUT jack on the right panel, or connect a microphone,
keyboard, or other line level audio source to the stereo mini LINE INPUT jack on the right panel.
Alternately, you can use the built-in condenser MIC for recording. As with any microphone, remember to
watch your monitor speaker levels when using the mic or feedback can occur.
Set the INPUT switch on the right panel to the appropriate setting (GUITAR for this exercise).
Connect headphones to the front panel mini jack (or powered monitors to the OUTPUT jack).
Power up, and listen to the demo songs:
1. Lower the [MASTER] fader to 0, and slide the back panel [POWER] switch two notches to your left, to
power-up with the display backlight (When you use batteries instead of the AC adaptor, you can switch
the backlight off to conserve power).
Set all four of the TRACK faders to 8.
Press the [>] key to begin playback of the first demo song (“DUCK TEETH”), slowly raising the
[MASTER] fader to a comfortable listening level. If using headphones, set the volume control on the front
panel to desired level. When finished, press [ ■ ].
Try the transport controls before you go any further; you’ll notice it works VERY MUCH like a
portable CD player, and should feel easy and familiar to you…During play back, holding down [I<<]
“rewinds” the audio data towards the song beginning. Pressing this same key once, while the song is
playing, re-starts the song beginning, and pressing [I<<] once, while a song is STOPPED to select the
preceding song. Holding down [>>I] “fast-forwards” the audio data towards the song end, pressing [>>I]
once, while a song is STOPPED or is playing, will select the next song, and songs can be chain- played by
holding down the SHIFT key and pressing [>].
About the SHIFT key:
The shift key is there to make your recording experience EASIER! Take a moment to look at your PXR4 front panel.
Every key or button has several functions, some written in back or orange, some written in silver on a black
background (like the “SHIFT” key). Every time you want to access a function that is written in the same color as the
“shift” key, simply press the “shift” key at the same time. No menus and endless parameters! Far from confusing, the
Mixer, Locate, and Effect/Tuner Modes:
MIXER mode:
In this mode, you can set volume level and pan location for each track. Use the demo songs to practice.
Press [>]. As the song plays, hold down SHIFT and press the [MIXER-DISPLAY-WRITE] key (above
the MASTER fader). Each time you press this key while holding SHIFT, you’ll cycle through PRE fader level,
POST fader level, and MIXER views, as indicated in the display.
PXR4 EasyStart
Leave the display in MIXER view (release the SHIFT key). Press the [MIXER-DISPLAY-WRITE] key
again, until the display reads, “Level 1”. Track 1’s volume can now be adjusted by rotating the DIAL, and
pressing the [►cursor] (RIGHT CURSOR) to view and adjust the Level of Track 2 (Each press of the
[►cursor] will advance through the four tracks).
Press the [▼cursor] to view and adjust the “Pan” and Master Effect “send” levels of each track with the
DIAL, navigating between tracks by pressing the [◄ and ►cursor]. (Press EXIT when finished)
The diamond-shaped “Page Guide Display” in the display always lets you know in what direction you can
navigate from your current page. It’s like a “compass”, and is designed to keep you from dealing with endless
“pages” and “menus”. See owner’s manual pg.63.
LOCATE and SYSTEM modes:
In the locate mode (pg 20) you can view the current musical (bars/beats/ticks) or time
(minutes/seconds/milliseconds) location in a song, or check the amount of time remaining on the SmartMedia
card. Simply press the [LOCATE] key to cycle through the modes. The system mode contains all of your digital
editing functions, such as time stretch, “cut and paste” style copy editing, and much more! Please consult your
owner’s manual (pages 55-64) for more features of these modes.
EFFECT mode:
In this mode (pg 20,62), you can work with the onboard effects, and the panel keys/faders that are printed in
orange let you perform effect-related edit functions. Four effect types are available: GUITAR, INSERT, MASTER
and FINAL, and the PXR4 includes 77 effect algorithms (including Korg’s amazing REMS sound modeling). If you
select GUITAR (for recording on input; mono/1 track only) or INSERT (for stereo instrument recording; stereo
in/out, stereo track bouncing, etc), you can apply effects as you record. If you select MASTER, you can send the
signal from any/ each track to an effect for overall processing. If you select FINAL, you’ll be able to apply an effect
to the master L/R bus, and use this effect as a mastering processor for track bouncing and other track-related
operations. Of course, the MASTER and FINAL effects are great to process your entire mix through as well.
For this demonstration, let’s hook up a guitar, bass, or keyboard (mono):
With playback stopped, hold SHIFT and press the [EFFECT/TUNER] key repeatedly, Cycling through
the four effect types as indicated in the display (under “EFFECT ASSIGN”), until you reach the “GUITAR” FX.
2. Press the Track 1 [REC SELECT] key. (A small circle will appear around the “1” in the lower left of the
display. This effectively “arms” the track, i.e., lets you hear and/or record the instrument you’re playing)
3. Press the [EFFECT/TUNER] key. The display will show an assigned effect program name and numberturn the DIAL to choose the desired effect program (numbered 00-49), and press the [EXIT] key repeatedly
to return to the main screen.
Guitar effect programs are numbered 00-49. Insert, Master, and Final effects share numbers 50-99. User
effect locations are similarly numbered, with an identifying “U” before the effect number.
TUNER mode (page 20)
Press the [EFFECT/TUNER] key, twice if you are not in effect mode, and you will access an ACCURATE, FULLY
CHROMATIC KORG TUNER! Pressing the [EFFECT/Tuner] key again will return you to the EFFECT screen, and
pressing [EXIT] will return you to the SONG NAME/LOCATE page.
Recording Basics
Delete the demo song(s) from the SmartMedia™ card:
The included demos use all the available recording space on the card. You will need to delete at least one
of the demo songs to do any new recording. Be sure to remove the WRITE PROTECT metallic decal from
the SmartMedia card, as this prevents you from altering the card’s contents. If you wish to save the demo

songs to your computer, please consult “Back up your songs to a computer” on page five of this
guide or page 51 of the manual.
Press the [EXIT] key until you select the initial song page.
2. Select the song that you wish to delete, and then press the [SYSTEM/RHYTHM] key 2x, until the
display indicates “EditSong” (P2), then press the [►cursor] to select “NameSong” (P21).
3. Press the [▼cursor] 2x, to select “DelSong” (P23), then press the [►cursor] 2x, to select “Del OK?”
(“YES” will flash).
4. Press the [►cursor]: the display indicates “Sure?” and rotates the DIAL to select “YES”, then press
the [►cursor]: the display indicates “Working”, then “Finish!”
Create a new song (page 23):
If there are no songs on the card, the display will indicate “Make New!” If there is at least one song on
the card, select the last song, and then press the [FF] key. The “Make New” message is replaced by
“SngGrade”. Rotate the DIAL to view the recording grades (with the included 16 MB card) as follows:
Economy, extended-length limited bandwidth recording
(Max. time, 16MB, 1 Track: 33’50”)
Standard, very high quality, normal use (Max. time, 16MB, 1 Track: 16’50”)
Ultra-high audio quality (Max. time, 16MB, 1 Track: 11’15”)
*For this exercise, select “Std” grade.
2. Press the [►cursor] and the display will indicate “NEW SONG” before returning to Locate Mode, and
displaying the counter position: “00.00.00”.
To rename the song, see page 24 of the owner’s manual.
Set the Tempo and Rhythm for the new song (pg 39):
Press the [SYSTEM/RHYTHM] key to select “Tempo” (P1).
Press the [►cursor] to display “BPM”, then “Beat”, then “Rhythm”, and slowly rotate the DIAL to
turn the rhythm “ON”. The cursor will also take you to the “level” adjustment if needed.
You can hear and select the metronomes and subsequent built-in rhythm patterns as you rotate the
DIAL. The drums NEED NOT be recorded to the tracks, but instead are always synchronized to the recorder,
and therefore, your recorded tracks! This means you can audition new grooves at ANY time!
Press the [EXIT] key (The rhythm playback will stop). For a list of rhythm patterns, available time
signatures, and recording count-in options, please refer to page 91 of your manual.
Record your first track (pg 25):
Arm the track(s) for recording by pressing the appropriate [REC SELECT] key.
2. Set the Levels: Adjust the front panel [INPUT TRIM] knob to achieve a fairly hot level without reaching
the “CLIP” level in the display, and then adjust the fader(s) for the record-armed track(s) to achieve a fairly
hot level without reaching the “CLIP” level in the display. (“Clip”indicates “distortion”).
3. Press the [REC] key. The “••REC” icon in the display will flash, and you’ll hear the previously selected
rhythm pattern; you are now in record-standby mode. Play your source instrument to rehearse, then…
Press the [>] key to record, and press the [ ■ ] key when you are finished recording.
5. Press the selected [REC SELECT] key(s) to disarm the record track(s), and then press the [I<<] key
once, to move to the song beginning. Listen to your results. To record the rest of your tracks, simply
repeat the previous steps for the next three tracks.
If four tracks is not enough, refer to VIRTUAL TRACKS, manual page 26, because there are 32 “tracks”
PXR4 EasyStart
Creating a two-track MP2 conversion for transfer and playback on your computer
The following exercise assumes that you already have standard media software installed on your computer,
since in order for you to playback in this way,, you’ll need to convert the PXR4 data to a stereo MP2 format file.
If you do not have the required software, you can download it from microsoft.com (Media Player) or apple.com
(QuickTime). Playback of PXR4 transferred audio currently works with Windows 2000, Windows 98 and Mac
OS 9.0. In the near future, PXR4 data will be compatible with Mac OS X.
(You can also transfer a SINGLE TRACK from the PXR4 to your computer for playback WITHOUT performing the
1. Make sure that the previous song is selected and set to play from the song beginning.
2. Hold down the [SHIFT] key, and then press the [LOCATE/BOUNCE] key until the display indicates
Press the [REC SELECT] keys for Tracks 1 and 2.
4. Adjust the playback/recording levels as needed while the song plays back. Reset to the beginning of the
song again, once you are satisfied with the playback levels.
5. Begin bounce recording: Press the [REC] key and the [>] key, and when the song has finished
playing back, press the [ ■ ] key.
A new song (sharing the same title) has been created in M-Peg audio layer 2 format.
Back up your songs to a computer (pg 51):
1. Connect a USB cable (not included) between the PXR4 rear panel [USB] port and your computer’s
USB port (PC or Mac).
Press the [SYSTEM/RHYTHM] key, and then press the [▼cursor] until the display indicates “USB
Press the [►cursor]. When the display indicates, “Ready?” rotate the DIAL to select “YES” and press
the [►cursor] once again. The display now says “CrdReady”.
4. On a Windows-based system, a drive named “Removable Disk” is added under ‘My Computer’. On a
Mac-based system, a drive named “Unnamed” is added to the desktop. (Make sure to leave the folders
intact whenever you backup or restore data. Do not open the folders and try to transfer files from
within, as the entire folder needs to be transferred.)
At this point, you can launch your media player-type software and hear your song, email it, or even burn
a CD from it.
6. To disconnect from your Windows PC, select the “Eject/Unplug” icon on the taskbar. Once you’ve
selected the drive, you will be prompted: “It is safe to disconnect the USB mass storage device”. If needed,
you can now unplug the USB cable. For Macintosh computers, drag the “Unnamed Drive” into the Trash,
or select to highlight the drive on the desktop, and then select “Eject” from the “Special” menu. Once the
PXR4 display changes from “CardLock” to “CdNotRdy” press the [►cursor]. The display indicates
“Complete” and “NO” is flashing. Dial in “YES” and press the [►cursor]. The display will return to Locate
Mode, and if needed, you may now unplug the USB cable.
Remember- there is much more to discover about your PXR4 in the detailed
and informative Owner’s Manual that came with your unit!
