Phrase Arpeggiation

Turn simple chord sequences into expressive melody lines and musical phrases. Simply design your phrase in the piano roll, and Phrasebox will play back the pattern using whatever notes you input.

You have complete control over how the phrase is played. Select notes in pitch order, or use the special selectors – such as the loudest/quietest or first-played/last-played. Your phrase will be played back with sample-accurate timing.

DAW-Like Control

Phrasebox isn't like traditional step sequencers or arpeggiators – you have full control over the timing and length of notes as you would in your DAW. Alongside velocity controls, you can also adjust each note's transposition, and even select a random chance that the note will play.

If your transpositions end up falling between the notes of a scale, you can enable the "Lock To Key" feature to make sure your riffs are always in tune.

Controller Editing

Alongside note patterns, you can also send MIDI controller data. With up to 8 assignable controllers, you can design everything from piano parts using the hold pedal, to automated synth filters and pitch bends to make the perfect melody line.


If you want quick access to an unlimited number of phrases, you can use the built-in generation tools to quickly get inspiration. Simply set how you want the notes and controller data to be generated, and Phrasebox will create a unique phrase pattern with just the click of a button.

To be honest, I don't quite get why a MIDI note-called sequence cannot just start right from its beginning exactly when it receives this note. Instead, it starts somewhere in the middle apparently counting when the next multiplication of a 4/4 bar is expected. Maybe I'm doing something wrong or maybe that's the way it works, but why?

Extremely pleased with this plug-in! Once I figured out how to use it with my DAW (Studio One) it was very obvious how useful it would be! Disclaimer: I am incredibly rusty as a player so this tool helps me take my ideas and compose quickly compared to all the hours of practice I would need otherwise. Love the interface as much as the concept.

Phrasebox really gives you an easy way to create complex phrases/arps/sequences. It has been updated often, with each updating adding great new functionality. This latest update (1.2.0) really adds a lot of extra features. It is the best arp/seqencer currently available on the market, in my opinion. Venomode have really created something special here.

Fantastic - by far my favored method of arpeggiating / sequencing is via a piano-roll interface, When NORA fell out of the market I waited patiently for someone to fill that role again. The ability to sculpt highly musical phrases with this much freedom cannot be matched by the standard grid approach.

As for responsive? I asked for live/trigger mode - I got live/trigger mode. This developer is fully engaged with the customer, and took the time to toss ideas back and forth with me via email - greatly appreciated! THAT'S how you do it :).

If anybody out there, like me, is a MIDI Modifier gourmand (trust me I've messed with a lot of them!), don't hesitate. Buy and enjoy this great product.
