BlueARP is a programmable pattern arpeggiator / step sequencer, it comes as a plugin for both Windows and Mac OS X. It's a pure MIDI plugin, so it has to be routed to either software or hardware synth in any VST-enabled DAW, such as FL Studio, Ableton Live, Cubase, Reaper, etc.), there is also MIDI FX version to use in Logic Pro X / MainStage on Mac.

Basically you need to program some pattern in BlueARP (it's quite fast with its matrix editor), then you play some chords and BlueARP will generate melodic phrases from this chords, according to the pattern you programmed. BlueARP was designed for electronic music genres (like trance, house, etc.), but it also may have some unexpected applications like triggering drums (it has swing feature).


  • Up to 64 steps per pattern;
  • Up to 128 programs per bank;
  • Intuitive matrix editor to program patterns quickly;
  • Up to 5 input keys;
  • Real-time input quantization (input quantize setting, pattern restart on beat / key);
  • Input range setting for keyboard-split performances;
  • Separate settings for octave and semitone per step transpose;
  • Chord recognition, it is possible to use 'root note' along with input keys.
  • Configurable color schemes;

Purchased Unify recently and have been working on learning the ins and outs of BlueARP. It's a bit of a learning curve, but the collaboration between Graywolf and John Lehmkuhl is a match made in heaven. While the price of Unify may keep some people from purchasing it, it is well worth the price (any price actually)! And putting the power of BlueARP in the Unify world gives the software capabilities that are impossible anywhere else! Try the VST in your DAW, then try the demo of Unify with BlueARP in your DAW (or freestanding) and you'll understand.

I have been playing around with this amazing plugin and it does exactly what I need to play live with my band but can someone please help me route Bluearp in Digital Performer 9.5?

I have tried it using Ableton and it works wonders but unfortunately my sequences are running out of Digital Performer 9.5 and I need this arpeggiator badly.

Thanks in advance.

A brief review: This plug-in is the best musical backing sequencing/arpeggiator ever made so far..

Detailed review:

For me, I've been always wondering why there's no such tool to make "key-altering arpeggiator" which corresponds to not only for the notes entered, but to the number of notes themselves, to alter the sequenced line from simplest to most complex.

This developer did it finally and he is a real poineer in this field just like Stephen Kay (the inventor of well known KARMA*). And the reason why this developer could do this tool is because he's much into arranger keyboards, those keyboards who are considered (by most of music developers) are just toys! The truth is, those arranger keyboards are the creative tools to inspire making good tunes & melodies.

Too many arpeggiator plug-ins exist, but non of them able to express the musician's ideas, flexible, altering with key strokes & creative... Because the developers who made those plugins were just thinking about normal/traditional 70's fashioned analog synth arps... While today's music genres are far beyond the old skool styles, there is always demands to introduce unique stuff, something to take the simpler notes into complex arrays of notes, well sequenced & most important (fully manageable).

It is great for all kind of Electronic genres, Trance, House, Dubstep, Psytrance etc.. But it is also can be good for some really epic orchestral backing accompaniments.. It all depends on user's imagination.

Inspiration level: It gives the maximum level, if you simply layer just a couple of this plugin (for bassline & for some chord hit) running along with decent drum sequence, you can have really great inspiration to make music in minutes...

I hope that I give a good details of this tool.. I really like it, it is essential to me...

I was looking for a good VST arpeggiator when I found this. It may not have the many bells and whistles of the big, expensive ones, but on the other hand I never need those. I just want something that offers a little more control than the built-in one of many synths. (Like support for chords.) This arp does exactly that, and it does so quickly and easily! Really, it's up and running in no time. I must admit that I didn't like the UI colors at all, but that was fixed quickly thanks to skinning support. Ever since, I've been having so much fun! I love this thing and recommend everyone looking for an arp to try this one out first.

This is SUCH a good arpeggiator! Send the MIDI to a 303 clone like ABL2 and you've got an instant acid machine of madness! :)

it does awesome basslines too and the trance stuff is just so pumping.. and thats just the presets.

The latch is so good for freeing up both hands whilst jamming and I like the way its inspired by the Novation super/nova arpeggiator (which i have) ... btw Graywolf's free NovaControl VST is also amazing if you're lucky enough to have one of those synths check it out too :)

great job.

Excellent arpeggiator.

Notice than it is also compiled in 64-bit, not only in 32-bit.

24 January 2017 at 9:48am

It is essential in everyday life ;). And a normal x64 .dll file (every free plug in should be as this)

Hello, .

Bluearp don't open the "Famous Arps & Basses by Opax v1.2"

He said it's not à preset for blueARP .x64.

I'm working on windows 7 64-bit.

What a useless piece of junk. Sure, it arps fine, and sequences fine, although it's SERIOUSLY lacking its own clock. Sync'ing may be what we want most of the time, but any sequencer should also be able to run independently of DAW clock.

But that's not why this is shit.

The reason this is shit is that it won't store anything. Save your project, reload it, and it's back to default settings. Just bam-bam-bam-bam-bam, same note, at 1/16 sync. Utterly useless.

Mind your words, especially if you lack the technological knowledge. Don't blame others for your own incapability.

19 November 2022 at 8:00pm

If you'd pull your head out of your **s and read the manual, or just poke around the interface you'd find multiple ways to save your presets.

10 October 2017 at 1:49am

I would echo the sentiments of Thohi, though not in such a self righteous aggressive manner. I'm assuming he has made a better arpeggiator.

Anyway, same problem that when I save and reload my bitwig project, the arp sequence doesn't save. Is there anything going on here that I need to check? Is it a compatability thing?

28 November 2021 at 2:56pm

Please don't make other people responsible for your own faults. The problem is not the software itself, the problem is sitting always in front of the computer! BlueArp is very good and it stores it's pattern very well. After giving the pattern a name and saving my Ableton project, everything is right in place, after opening the project again.

Thank you Oleg.

Don't listen to the haters.

I have used this product for years, and it's absolutely brilliant. Easy to understand and negotiate. I will continue to follow this program for years to come. Probably the best arpeggiator out there .

9 January 2019 at 4:41pm

I agree.I love this thing.

10 December 2017 at 5:18am

Discovered that it depends on where i install and save files.

There's the issue of not being allowed to save to a location then the program doesn't load up the factory banks or saved banks.

10 January 2019 at 3:43am

MIDI Program change works and items in the preset menu are chosen sequentially - but how does one rearrange, store and add programs to change that initial menu? Thank you for your reply.

10 January 2019 at 4:06am

Saving patches is done from the main menu. Copy, insert/paste and overwrite/paste allow placing patches in desired order. Save the bank, and that bank is loaded on next startup.

30 July 2022 at 1:47pm

Anyone know how you can get this thing to sync with Ableton? It just plays out of time for me.

29 August 2022 at 5:33pm

The preset banks won't load in BlueArp 2.3.8 "not for this plugin". What's the matter? How can I fix this?


8 October 2022 at 9:07am

Thanks a lot. I'd like to ask where I should put this preset in.
