MIDI effects
Now, the notes in the dropped MIDI part will be sorted in-
ternally, either according to their pitch (“MIDI Seq. sort by
pitch” checkbox activated) or according to their play order
in the part. This results in a list of numbers. For example, if
the notes in the MIDI part are C E G A E C and they are
sorted according to pitch, the list of numbers will read 1 2
3 4 2 1. Here, there are 4 different notes/numbers and 6
trigger positions.
The MIDI input (the chord you send into the Arpache SX)
will generate a list of numbers, with each note in the chord
corresponding to a number depending on the “Sort by”
setting.
Furthermore, the two lists of numbers will be matched –
the Arpache SX tries to play back the pattern from the
dropped MIDI part but using the notes from the MIDI input
(chord). The result depends on the Play Mode setting:
Note also that you can choose to keep the original note
timing, note length and note velocities from the dropped
MIDI part, by selecting “from sequence” for the Step Size,
Length and Velocity options.
Auto LFO
This plug-in works like an LFO in a synthesizer, allowing you
to send out continuously changing MIDI controller mes
-
sages. One typical use for this is automatic MIDI panning,
but you can select any MIDI continuous controller event
type. The Auto LFO effect has the following parameters:
Waveform
These settings determine the shape of the controller curves
sent out. You can click on a waveform symbol, or choose a
value from the pop-up menu.
Wavelength
This is where you set the speed of the Auto LFO, or rather
the length of a single controller curve cycle. Using the
slider or by choosing an entry from the pop-up menu, you
can set this to rhythmically exact note values (or PPQ val
-
ues if the PPQ button is activated). The lower the note
value, the slower the speed. For example, if you set this to
“1/8”, the waveform will be repeated every eighth note.
Controller Type
Determines which continuous controller type is sent out.
Typical choices would include pan, volume and brightness,
but your MIDI instrument may have controllers mapped to
various settings, allowing you to modulate the synth para

meter of your choice – check the MIDI implementation chart
for your instrument for details!
Option Description
Trigger The whole pattern from the dropped MIDI file will be played
back, but transposed according to one of the notes in the
MIDI input. Which note is used for transposing depends
on the Sort by setting.
Trigger Cnt. As above, but even when all keys are released, the phrase
continues playing from the last position (where it stopped),
when a new key is pressed on the keyboard. This is typi
-
cally used when playing “live” through the Arpache SX.
Sort Normal Matches the notes in the MIDI input with the notes in the
dropped MIDI part. If there are fewer notes (numbers) in
the MIDI input, some steps in the resulting arpeggio will
be empty.
Sort First As above, but if there are fewer notes in the MIDI input,
the missing notes will be replaced by the first note.
Sort Any As above, but if there are fewer notes in the MIDI input,
the missing notes will be replaced by any (random) note.
Arp. Style As above, but if there are fewer notes in the MIDI input,
the missing notes will be replaced by the last valid note in
the arpeggio.
Repeat In this mode, the chords played will not be separated into
notes. Instead they will be used as is, and only the rhythm
of the dropped MIDI part is used for playback.
