slider to control the overall
volume of the instrument.
This slider controls the vol‐
ume of the sound going to
the internal speakers,
the L/MONO & RIGHT
OUTPUTS, and the HEAD‐
Note: Start at a moderate level,
then raise the MASTER VOLUME up. Don't keep the volume
at an uncomfortable level for too long.
Use the ACC/SEQ VOLUME slider to control the Style
tracks (drums, percussion, bass...) volume. This slider
also controls both of the Sequencers tracks, excluding
the Realtime (Keyboard) tracks.
By default, you can use the ASSIGN.SLIDER to control

THE BALANCE SLIDER

onboard sequencers (Sequencer1 and Sequencer 2).

You can connect a pair of headphones to the rear panel head‐
phone jack (PHONES: stereo mini‐jack). You can use head‐
phones with an impedance of 16–200Ω (50Ω recommended).
You can send the sound to an external amplification system,
instead of the internal speakers. This is useful when record‐
ing, or when playing live.
You can connect the output of another electronic musical
instrument, an unpowered mixer, or any audio device to the
rear panel input jack (INPUT: stereo mini‐jack). Since this is a
line‐level input, youʹll need to use a separately sold mic pre‐
amp or mixer if youʹre connecting a mic.
Use the connected device's volume control to adjust the input
level. Be careful not to make it distort (or "clip"). Here is how
to set the volume of the connected device:
if the sound heard on microARRANGER's outputs is too
low, you should increase the output level of the con‐
if it sounds fine, it's ok.
if it distorts, you should lower the level a little, until the
sounds is fine again.
You can play the internal sounds of your microARRANGER
with an external controller, i.e. a master keyboard, a MIDI
guitar, a wind controller, a MIDI accordion, or a digital piano.
Connect a standard MIDI cable from the MIDI OUT of
your controller to the MIDI IN connector on the micro‐
Select a transmission MIDI channel on your controller.
Some controllers, like the MIDI accordions, usually
transmit on more than one channel.
On the microARRANGER, select the MIDI Setup that
best fits your controller's type.
Connect a Damper (Sustain) pedal to the DAMPER connector
on the back panel. Use a KORG PS‐1, PS‐3 or DS1H foot‐
switch pedal, or a compatible one.
Listen to the built‐in Demo Songs to appreciate the power of the
microARRANGER. There are 16 Demo Songs to choose from.
Press the STYLE PLAY and SONG PLAY buttons
together. Their LEDs start blinking.
At this point, if you don't press any other button, all the
Demo Songs will be played back.
Choose a page using the PAGE buttons. There are two
different pages in the Demo mode.
Select a Demo Song by pressing the corresponding VOL‐
UME/VALUE button around the display. The Demo will
Stop the Demo by pressing START/STOP.
