The Arpeggiator Section
A well-designed arpeggiator can make someone who’s new to music sound like a pro. Add a bit 
of music theory and some sound design chops to the mix and the results can be amazing. The 
presets make an ironclad case for that.
An overview of the Hydrasynth arpeggiator features was provided in the Arpeggiator basics 
(p.11) section of the Quick Start Guide. This included the similarities and dierences between 
the controls of the keyboard and desktop models. The main focus of this chapter is to describe 
the arpeggiator parameters and how to use them.
Arp Edit Mode
To enter Arp Edit mode, hold the [SHIFT] button and press [ON] in the Arpeggiator section of 
the top panel. The Right display will reveal the rst eight parameters of Arp Edit mode. Use the 
Page Down arrow to access the second page of parameters.
Arp parameters: page 1
Tempo
Use Control knob 1 to adjust the tempo, or 
press [TAP TEMPO] three or more times to 
set the tempo manually. Hold [SHIFT] while 
turning Control knob 1 to ne-tune the 
tempo. 
If Clock Sync is set to an external source the 
letters EXT will be shown prior to the tempo. 
This setting is found on MIDI: Page 4 (p.86). 
Division
Control knob 2 selects the basic time division 
of the arpeggiator relative to the tempo. There 
are 12 settings here, 4 more than the top 
panel knobs can reach. The Triplet options are 
there too, and the Triplet LED will light as they 
are selected. You can also press [TRIPLET] to 
select that setting immediately.
Swing
The top panel Swing knob oers eight 
settings, including O. But there are actually 
26 settings between 50% and 75%. Use 
Control knob 3 to select a value, or use the 
Swing knob rst and then Control knob 3 to 
select a nearby value.
Gate
Turn Control knob 4 to adjust the relative 
duration of the arpeggiator notes. The full 
range of the parameter is available here for 
both models: 5% to 100%.
Octave mode
This parameter is not present on the top 
panel. It works together with the Octave 
setting, which must be >1 or you may not 
hear a dierence. Use Control knob 5 to select 
the options. The descriptions are based on an 
Octave setting of 2 except as noted:
• Up plays the notes in the original octave 
and then repeats the pattern an octave 
higher.
• Dn (down) plays the notes in the original 
octave and then repeats the pattern an 
octave lower.
• UpDn (Octave = 3) plays the notes in the 
original octave, repeats them in the next 
2 octaves, repeats them in the middle 
octave, and starts over.
• Alt plays the notes in the original octave, 
repeats them in the next octave, and then 
reverses the entire pattern. The top and 
bottom notes are repeated.
• Alt 2 is identical to Alt except the top and 
bottom notes are not repeated.
Octave
Use Control knob 6 to set the range of the 
arpeggiator. Minimum range is 1 octave; 
maximum range is 4 octaves.
