H-Arp is a programmable MIDI arpeggiator with a vertical tracker style interface that makes it fast, simple, and fun to create sequences.

H-Arp is a MIDI only DAW plugin for triggering other instruments. Please try the demo first to ensure it works for your DAW, see the DAW setup guide.

How it works

Chords you press on your MIDI keyboard go into Notes Pressed slots whilst the tracker plays down through steps vertically. The event numbers at each step in the grid decide what note slot(s) at the top get played.  A surprisingly simple concept, yet powerful and inspiring through playful experimentation. 

Note length (gate), velocity and other per step row parameters can be edited on the right of the grid, with various complementary playback options.

Trigger your favourite software or MIDI hardware instruments from within your DAW using the arp and create patterns faster than ever before, with drag & drop MIDI export. Will you ever use the piano roll again?!

I've had some reports of the Windows installer zip being false flagged by AV (an InnoSetup problem I believe), so there is also zip containing just the VST3 and some install instructions until I find a better installer.
