Sytrus - Arpeggiator best seo firm, am pm.

 Sytrus has a unique method of creating
arpeggios (Arps). Arps are defined by Envelope (usually volume,
modulation or filter) arpeggiator 'break-points' that can be
applied to the Envelope nodes. See Working
with Envelopes for more detail on the basics of Envelope
manipulation.
There are three types of Envelope Break Points used for making
arpeggios (the middle three in the picture left),
Previous, Same,
Next. The first and last nodes relate to the loop
start and end points (Loop Sustain start and
Loop Sustain End respectively).
When a chord is played, and the envelope is set to arpeggiate,
each of the notes in the chord has its 'turn' in the envelope loop
as defined by the Arp break-point flags. The Arp break-points are
described in more detail below.

Settings
To add or change an arp break-point -
right-click on the envelope node and select
'Arpeggiator break' from the pop-up menu, then
select one of the following break-point types from the
sub-menu.
- None - Use this to clear an unwanted break
point.
- Previous, Arp DOWN (
 ) - At the break-point sound the next note
below the previous note played.
- Same, REPEAT (
 ) - Sound the same note as at the last
break-point.
- Next, Arp UP (
 ) - At the break-point sound the next note above
the previous note played.
Making an Arp
- Open Sytrus and load the patch labelled
Default (this is a simple sine-wave on Operator
1).
- Select Operator 1, set the Editor target to
VOL and the Articulator part to
ENV (this will open up the volume envelope for
Operator 1 and the same windows should be open as shown in the
picture above).
- From the Envelope Options menu (
 ) select the Open state
file... menu item and open the 'Arp - classic
up.fnv' state file.
- You should now be looking at a simple triangle shaped Envelope
with a Same break-point on the first node and a
Next Arp break-point at the last node. Playing a
chord will sound the classic upward repeating Arp.
- Try changing the last node to Previous and
note that Arp now descends. From here you should experiment by
adding some more Envelope nodes and break-point types. You are now
on you way to creating your own Arps, have a look at some of the
other Arp presets and learn how they work.
Notes and Tips:
- Arps need chords: To hear an Arp you need to
play a chord (otherwise there is no 'previous' or 'next' note for
Sytrus to play). Single notes will work, sounding the rhythm of the
Envelope.
- Envelope loops: If you want your Arp to repeat
while you hold down the chord, the first node should be set to
Sustain loop start and the last node should be set
to Sustain loop end (it is possible to add both
Arp 'break points' and 'Loop sustain' flags to the same node).
- Envelope release: Avoid Envelope releases with
Arp presets (a 'release point' envelope data after the 'Sustain
loop end' node) as the envelope will play the whole chord.
- Timing: Make sure Tempo and
Global selectors are activated in the Envelope
settings so that the Arp plays in time with the BPM of your project
and timing of the notes do not drift relative to each other.
- Per-Operator Arps: The speed of the Arps can
be varied on an 'per operator', basis, very complex and 'cool'
patterns are possible.
- Speed: The envelope 'decay' (DEC) knob can be
used to speed up or slow down the sequence. The knob is set to 2X
speed increments.
