MelodicFlow - Play harmonic melodies instantly


Stop worrying about wrong notes. Concentrate on melodic rhythms instead.

Use the MelodicFlow plug-in (VSTi, AU) to create and play stunning basslines, arps, and melodies quickly. You will never sound off, as all your input is mapped to the right notes immediately.

The one thing that makes songwriting challenging


Does this sound familiar?

  • You know which chords you want to use in your song, but you have no ideas for the melodies yet.
  • You want to jam around on your keyboard, but you constantly pick the wrong notes while playing.
  • You know exactly the "shapes" of your melodies: You know when they should play higher or lower, when they should go up or down. But you have a hard time to put that into notes.

MelodicFlow helps you to play and compose melodies faster than ever before.

What customers say

Just bought MelodicFlow & SunDog, I use Reaper that have lots of scripts/stuff, but your software is so nice/clear plus the videos/documentation. Pictus
I bought and downloaded MelodicFlow a week or two ago and absolutely loved it - what it does is something I've been looking for for a long time and it does it well. Ian E.
Great plugin - really opens up the compositional process and moves beyond a conventional arpeggiator. Helps me keep my flow. Sam
It took me a bit to understand what MelodicFlow is for, but now that I get it… love it! Chris H.
I have Chordpotion, Sundog, House Engine and Melodicflow and they have helped me so much when i am making new music. Thank you for always working to make updates also, the plugins are extremely good value and more valuable than a lot of other plugins out there. You have made music more accessible to novices like me and i am extremely grateful. Marty
Thank you for taking the time to develop this product. Over the years, I’ve attempted to achieve such results via scripts and formulas and never quite got it right. What you’ve developed is so to-the-point and exactly what I’ve actually envisioned as a best-case scenario, it’s as if you wrote it specifically for me. Thank you for your brains and discipline, I get to enjoy it. Coatsie

This is how it works

Main elements

Basically, you only have to put the MelodicFlow plug-in (VSTi, AU) between your keyboard and another instrument. Then you start to jam around on the white keys of the upper octave and MelodicFlow converts your input to safe notes.

Follow these steps to improvise fitting melodies at once:

  • Connect MelodicFlow to another instrument inside your DAW.
  • Send chord notes to MelodicFlow on the lower octaves. This way the plug-in knows which harmonies are important for your song.
  • Pick one of the seven operation modes and choose a scale.
  • Now play on the white keys of the higher octaves. Depending on the operation mode MelodicFlow will automatically convert these keys to harmonic notes that fit to your chords and the chosen scale.

There are also special black keys that are useful for your songwriting. The C#6 for example will play all the notes of the current chord at once. Take a look at the comprehensive manual to find out more. The video at the top of this page will show you an example for a real life production.

Perfect for your studio productions

MelodicFlow will speed up your music productions immediately.
Simply write down your chords and pick a scale from the MelodicFlow menu. No need to worry about wrong notes anymore, you only have to draw in melodic rhythms in your DAW.


A simple arpeggio within seconds.


This bassline follows your chords.

Backbeat chords

Backbeat chords. Quick and easy.

Some examples:

  • The bassline should follow your chords? Create a simple rhythm inside your DAW. MelodicFlow will take care of the rest.
  • You need to change your chords later on? Replace them with new ones. The melodies, arps, and basslines will follow along.
  • You created a complex melody in another track? Copy the melodic rhythm to your new track. Done.

In some DAWs it's even possible to create a "master chord track". This track pushes all the chord notes to various MelodicFlow plug-ins. If you need to change your chords, you only have to do this in one place now. Perfect if you are pressed for time and need to create a bunch of tracks in a hurry. Find out more here.
