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.
