MOD Arpeggiator Plugin

This arpeggiator is a LV2 plugin, made for the MOD platform. The GUI is design is made by André Fernandes.

The arpeggiator has the following options:

  • Tempo options:

    • There are a few options too set the tempo of the plugin. The first one is the Free Running mode. In this mode the tempo is controlled by the BPM control of the plugin.
    • On top of the BPM control there is a Divisions control.
    • The plugin can also be synced to the host.
  • Arpeggiator modes:

    • The arpeggiator has the following modes:
  • Octave Modes:

    • The arpeggiator has octave spread control. The arpeggiator can iterate the incoming notes over multiple octaves. This control sets the range of the octaves that will be iterated over the original pitch. The way how this octaves will be added to the original notes is determent by the octave mode control.


Here is a small demo video of the arpeggiator. The synth that is used is the Behringer Neutron in combination with the Shiroverb-mkII plugin on the DUO X.


The MIDI-pattern plugin is part of the arpeggiator project and can be used to create rhythmic patterns. The plugins takes the incoming note and replaces the velocity of the note by a value which is set by one of the faders of the plugin. Because the plugin iterates through the faders it generates a sort of rhythmic sequence. The CV control of the plugin can be used to retrigger the sequence.


  • The plugins can be used outside of the MOD ecosystem. But because they are developed for usage inside the MOD there might be things that won’t work properly.
  • The plugins contain lv2 “CV ports”, this feature is not supported by all plugin hosts (yet).
