What is BlueARP plugin

BlueARP plugin is a programmable pattern arpeggiator / step sequencer. It is available both on Windows (VST plugin) and on OSX (VST and MIDI-FX plugin), free of change, ready to use in your music production and performances, either commercial or not.

It has no pesky limitations or nudging to buy a ‘pro-version’, no annoying ads. You are welcome to send me a donation if you like BlueARP plugin, but you don’t have to.

The interface may look scary for the beginner, but here you have all your sonic controls on one screen, only rarely used settings are hidden to the other tabs:

BlueARP is a pure MIDI plugin, it doesn’t generate any sound by itself but transforms MIDI messages. It has to be routed to either software or hardware synth in any DAW (Digital Audio Workstation) software like FL Studio, Ableton Live, Cubase, Reaper, Logic Pro, etc.

BlueARP was designed for electronic music genres (like Trance, House, etc.). It is perfect for that fast ‘trancey’ and ‘cosmic’ arpeggios, arpeggiated bass lines, gated pads; it works for step sequencing as well. Also it may have some unexpected applications like triggering drums.
