Parts and their functions
1. Trigger pads
These pads can transmit note messages or control change messages. Ideal for percussion passages or
sample triggering.
2. Keyboard
There are twenty-five velocity-sensitive keys which transmit note messages.
When CC mode is on, these will transmit control change messages.
3. MIDI control group
A Rotary & slider controller, are collectively called a MIDI control group.
The Micro MU has 4 MIDI control groups.
a. Rotary
This rotary transmits control change messages, increasing with clockwise rotation
b. Slider
This slider transmits control change messages, increasing when pushed forwards
4. OCTAVE SHIFT
The [◄] button and the [►] button can be used to shift the octave down or up respectively. The pitch
will shift down by one octave for each press of the [◄] button.
The pitch will shift up by one octave for each press of the [►] button.
5. Bank button
The Micro MU has four banks. When the BANK button is on, you can use the [◄] button and the [►]
button to switch between the four banks. A “bank” is a set of parameter assignments for the controllers
(pads and knobs, etc.).
You can use Micro MU Editor to change the assignment of each controller. (see below “Making detailed
settings”)
6. Program button
When program button is on, you can use the [◄] button and [►] buttons to change the program.
7. PITCH BUTTONS
The [PITCH DOWN] and the [PITCH UP] buttons can be used to send a note’s pitch up or down in
cents.

Making detailed settings
The following settings cannot be edited on the Micro MU instrument, so you need to use the Micro MU
Editor software for these. The Micro MU control Editor can be downloaded from www.avsl.com.
Global MIDI channel
Global MIDI channel [1...16] This specifies the MIDI channel which Micro MU will use to transmit note
messages, as well as MIDI messages that will be send when you press the button. This should be set to
match the MIDI channel of the software application that is being used.
Keyboard CC mode channel
Piano keyboard CC mode channel is to specify which MIDI channel the keyboard will use to transmit control
messages.
Transpose
The Transpose function adjusts the pitch from -12 to 12 semi-tones.
Pitch bend speed
It is to adjust the speed of the pitch up or down- adjusting scale is from 1 to 4.
Key velocity curve
3 velocity curves can be applied to keys (Light, Medium, Heavy) and Constant (i.e. not touch-sensitive)
Pad velocity curve
3 velocity curves can be applied to pads (Light, Medium, Heavy) and Constant (i.e. not touch-sensitive)

Trigger pads
Depending on the assign type, the trigger pads can transmit note messages or control change messages.
For each trigger pad, you can individually specify the assigned message, the MIDI transmit channel, the
behavior of the trigger pad, the note number, the control change number and the values transmitted when
the pad turns on or off.
Depending on its assign type, note number or control change number can be assigned to a single trigger
pad and transmitted. If you transmit note messages or control change message from a trigger pad, these
messages will be transmitted at the velocity or on/off value from the pad.
MIDI Channel [1...16/Global MIDI Channel] This specifies the MIDI channel that the MIDI messages
are transmitted to when you strike the trigger pad. If you set this to “Global MIDI Channel,” the messages
will be transmitted on all MIDI channel.
Assign Type [No Assign/Note/Control Change]
This specifies the type of message that will be assigned to the trigger pad. You can disable the pad (no
assignment), or assign a note message or a control change to the pad.
Pad Behavior [Momentary/Toggle]
You can choose one of the following two types of behavior for the trigger pad.

169.010UK User Manual
Momentary The Note On or On Value will be transmitted when you press the trigger pad, and the Note Off
or Off Value will be transmitted when you release it.
Toggle The pad will act as a latching switch-pressing once for “ON” and again for “OFF” alternately.
Note Number [C-1...G9/No Assign]
This specifies the note number of the note message that is transmitted.
Control Change Number [0...127/No Assign] [0...127] This specifies the control change number of
the control change message that is transmitted.
On Value [0...127] Specifies the value of the message that is transmitted when the trigger pad turns on.
Off Value [0...127] Specifies the value of the message that is transmitted when the trigger pad turns off.
(You can set this only if the assign type is “Control Change.”)
Rotary Knobs
Operating a knob will transmit a control change message. You can enable/disable each knob, specify its
control change number, and specify the values transmitted when the knob is turned fully left or fully right..

169.010UK User Manual
Enable [Disable/Enable]
Enables or disables the rotary knob. When disabled, turning the control will not transmit a MIDI message.
Control Change Number [0...127]
Specifies the control change number of the control change message that is transmitted.
Left Value [0...127]
Specifies the value of the control change message transmitted when you turn the knob all the way to the left.
Right Value [0...127] Specifies the value of the control change message transmitted when you turn
the knob all the way to the right.
Sliders
Operating a slider will transmit a control change message. You can enable/disable each slider, specify its
control change number, and specify the values transmitted when the slider is moved fully upward or fully
downward.
Slider Enable [Disable/Enable]
Enables or disables the slider. If a slider has been disabled, moving it will not transmit a MIDI message.

169.010UK User Manual
Control Change Number [0...127]
Specifies the control change number of the control change message that is transmitted.
Upper Value [0...127]
Specifies the value of the control change message transmitted when you move the slider all the way upward.
Lower Value [0...127]
Specifies the value of the control change message transmitted when you move the slider all the way
downward.
Keyboard operation in Edit mode
The twenty-five keys of the keyboard will function as independent buttons to transmit control change
messages. You can specify which MIDI channel the control change message is transmitted on, whether or
not each key is enabled, the key type, the control change number, as well as the On and Off value.
CC MIDI Channel [1...16]
This specifies the MIDI channel that control change messages will be transmitted on. Set this to match the
MIDI channel of the software application.

169.010UK User Manual
Key Enable [Disable/Enable]
Enables or disables the key. If a key is disabled, operating that key will not transmit a MIDI message.
Key Behavior [Momentary/Toggle]
Selects one of the following two modes:
Momentary Pressing the key will send a control change message with the “ON” value, releasing the key
will send a control change message with the “OFF” value.
Toggle The key will act as a latching switch-pressing once for “ON” and again for “OFF” alternately.
Control Change Number [0...127]
Specifies the CC number of the control change message that will be transmitted.
On Value [0...127]
Specifies the “ON” value of the control change message.
Off Value [0...127]
Specifies the “OFF” value of the control change message.
