Introduction
This chapter describes the available MIDI modules. For in-
formation on using and setting up MIDI Modules, see “Us-
ing MIDI Modules” on page 54.
The FlexPhraser
HALion features an arpeggio and phrase player: the so-
called FlexPhraser. You can select from a great variety of 
phrases that suit a wide range of musical instruments and 
styles. Depending on the selected phrase, the FlexPhraser 
uses your live playing to modify the phrase in real-time. 
This allows...

Hold
Here, you can make the following settings:
Trigger Mode
The Trigger Mode defines when the FlexPhraser scans for 
new keys you play on the keyboard.
The following options are available:
Restart Mode
Here, you can make the following settings:
Key Mode
This option defines if the order of the notes, as played on 
the keyboard, affects the playback of the phrase.
The following options are available:
Vel Mode
This option specifies how the velocity of the notes you 
play affects...

Tempo Scale
This parameter defines the rate at which notes are trig-
gered, in other words, the speed at which the phrase is 
running. You can specify a value in fractions of beats. You 
can also set dotted and triplet note values. 
When the Tempo parameter is 1/16 and you set this value 
to 1/8, for example, the speed is cut to half. When you set 
it to 1/32, the speed is doubled. Other values increase or 
decrease the speed accordingly.
Swing
Use this parameter to shift the...

Switching Variations with the Trigger Pads
You can switch between variations using the trigger pads 
(see 
“Switching between FlexPhraser Variations” on page 
145).
The Trigger Pads
You can use the trigger pads to trigger single notes or 
whole chords and to switch between FlexPhraser varia
-
tions. Many of the programs that come with HALion make 
use of the trigger pads:
•Blue pads have single notes or whole chords assigned.
•The line above the pad turns orange when the pad...

ÖTo use the pads for switching between expressions, 
select “Snapshot Chord” on the context menu and play 
the corresponding key switch.
ÖIf you define a chord that also contains a key switch, 
you can trigger the chord with a specific instrument ex
-
pression.
ÖIf you add keys to a chord that also work as trigger 
notes, they trigger the underlying MIDI note instead of the 
trigger note.
•To clear the chord or note from a pad, right-click the 
trigger pad and select “Clear...

Trigger Mode
On the Trigger pop-up menu below the envelope display, 
you can set the condition for triggering the envelope.
Release Mode
On the Release pop-up menu below the envelope display, 
you can set the condition for releasing the envelope.
Level Velocity
Use this parameter to adjust how velocity affects the level 
of the envelope. The level of the envelope depends on two 
factors: the setting of this parameter and how hard you hit 
a key. Positive values increase and...

Mono LFO
HALion allows you to add monophonic LFOs as MIDI 
modules to the program. An LFO module can be used for 
an entire program, or for specific layers. In this context, 
monophonic means that these LFOs are only calculated 
once and feed multiple voices at the same time. A pitch 
modulation controlled by the modulation wheel is a typical 
example where one LFO controls the vibrato for all voices. 
Monophonic LFOs appear as sources in the modulation 
matrix of the zones...

Retrigger Mode
Determines whether the LFO is restarted when a note is 
triggered. When Retrigger is set to First Note or Each 
Note, the waveform starts at the position specified by the 
Phase parameter.
LFO Bypass
To hear the sound without any LFO modulation, click the 
Bypass button (the speaker icon) in the title bar of the 
section. This deactivates all LFOs.
MegaTrig
The MegaTrig module is used for controlling playing styles 
and articulations and for triggering release...

Selecting a Condition
You can combine up to 8 conditions into an expression 
using logical operations. For example, the expression 
“Note-on AND Sustain On” is TRUE when you play notes 
while holding the sustain pedal down. Any assigned zones 
only play back if the whole expression is TRUE. 
For each of the conditions, you can make the following 
settings:
The following options are available on the Condition pop-
up menu:

MIDI Modules Reference
ÖTwo MIDI note events combined by an AND operation 
can never turn TRUE. For example, the expressions “Note-
on AND Note-off”, or “Note-on AND Key up”, or “Note-off 
AND Key up” can never be TRUE.
ÖWhen using several MegaTrig modules, the random 
value is the same across all MegaTrig modules, if you se
-
lect the Random option in the same row. By setting the 
ranges so they do not overlap, you can switch randomly 
between the corresponding layers.
