Korg m50-73 User Guide

This slider adjusts the volume of the AUDIO OUTPUT 
L/MONO, R outputs, as well as the volume of the 
headphone jack. (See page 23)

These switches are used to control the programs or 
effect parameters, or to turn the joystick lock function 
on/off. (See page 19)

You can control synthesis parameters or effect 
parameters by moving the joystick up/down/left/
right. (See page 19)

The control surface consists of the four knobs located 
to the left of the display, the three REALTIME 
CONTROL, EXTERNAL, and ARP switches, and the 
RESET CONTROLS switch that resets the function of 
these controls.

You can use these as realtime controllers to modify the 
sound, as external controllers to transmit MIDI 
messages to an external MIDI device, or to control the 
arpeggiator.

As explained below, you can use the front panel 
CONTROL ASSIGN switches to switch between the 
various control surface functions. You can also view 
and edit the control surface settings in the display (P0–
8: Control Surface page in each mode).

The functions of these four knobs will change based on 
the REALTIME CONTROL, EXTERNAL, and ARP 
switches, as described below. 
For more details, please see “Control Surface knobs” 
on page 20.

When you press this switch, knobs 1–4 will modify the 
sound and effects. You can press this switch repeatedly 
to cycle between different control functions. (See 
page 20, and page 30)

When you press this switch, knobs 1–4 and chord 
trigger switches 1–4 will transmit MIDI messages to an 
external MIDI device. You can press this switch 
repeatedly to cycle between different control functions. 
(See page 85, and PG page 224)

When you press this switch, knobs 1–4 will control the 
arpeggiator settings. (See page 73)

This resets the controllers of the control surface, 
returning them to the saved values or default values.
