RandARP is a VST plugin arpeggiator with many randomization features, allowing incoming notes or chords to be manipulated in various rhythmic ways. All standard arpeggiator parameters like number of octaves, note length and note order are included, but the plugin also offers complete randomization of the velocity, gate, shift and swing parameters. In addition, you can specify a note probability and randomize the note order, the octave order, and the number of octaves. All the randomization features allows you to create more interesting and unpredictable arpeggiated sequences.
Windows XP/Vista/7/8/10. VST2 compatible 32-bit or 64-bit host.

Download & Installation
Click "Download", open the downloaded zip file and extract the dll file to your VST plugin folder (RandARP32.dll if you use a 32-bit host, or RandARP.dll if you use a 64-bit host).
- Support for hiDPI displays. Select scaling (100%, 125%, 150%, 175%, 200%, or Auto) from the main menu.
- Now possible to enter a specific value by right-clicking a
control and choosing 'Enter Value' from the
popup menu, or simply by double-clicking the control.
- The current knob value is now shown below the knobs.
- Easier to select middle knob value with a MIDI hardware controller (can be selected with both MIDI CC value 63 and 64).
- Possible to change the data folder location containing the settings and preset files with a shortcut file.
- Fixed: Crashed in Reaper if clicking in timeline when transport was running.
- Fixed: Did not work in Image-Line Mini Host standalone.
- Fixed: GUI issues when Windows 10 app scaling was set to "System (Enhanced)" for non-hiDPI hosts.
- Various minor fixes and enhancements.
- Fixed: Dialog boxes shown behind plugin window in Reaper if plugin window was pinned ("stay on top").
- Fixed: Poly Aftertouch and Program Change midi messages not passed through plugin.
- Length parameter renamed to Rate.
- Added a free rate mode, not synced to the host's tempo/grid. Use the new Speed parameter to scale the step length from 0.25x and up 4x of the arpeggiator rate. For example, if Rate is 1/8 and Speed is 0.50, the length of each step is now a quarter note. If Rate is 1/8 and Speed is 2, the length of each step a sixteenth note. But you can of course use Speed to set up a step length to be in-between standard rates, for example 1.10 which will give you a step rate that is 10% faster than the selected rate.
- Added 3 new random options: Note Order/Random Once, Note Order/Random Oct Once and Octave Order/Random Once. This will create a random pattern, but repeat this pattern until the input notes changes.
- In all right-click popup menus showing parameters values, the highest value is now shown at the top of the menu.

- Fixed: Plugin would crash/plugin window not display on some Windows installations.
