Typically, when we say something is free for a limited time, you have a week or more to take advantage of the offer. At the time of writing, you have around a day and a half to download HARMO for free before it returns to its regular price of $25 (the offer ends on September 4, 2025).
Harmo requires the full version of Native Instruments Kontakt version 6.4.2 or higher.
If you don’t have the full version of Kontakt or you’re looking for a great deal with a little more time left on the clock, check out Native Instruments Monark. You can grab a massive 80% discount on Monark at Plugin Boutique until September 30, 2025.
Harmo focuses on the unmistakable tone of natural guitar harmonics, more specifically, the natural harmonics of a classic Stratocaster.
I know that a guitar harmonics library might not instantly seem like the most versatile collection, but harmonics are more than highlights or range extenders in intricate guitar recitals.
There are numerous examples of guitar harmonics used in famous songs; She Talks to Angels by The Black Crowes is a great example. If we jump to the bass guitar, players like Pino Palladino often snuck in the most beautiful use of harmonics, and of course, Jaco Pastorius with the stunning Portrait of Tracy.
Most examples showcase the use of harmonics to enhance melodic content, but you can also find people making entire melodies from guitar harmonics.
Harmo adds versatility by allowing you to introduce additional layers, like Piano, Bells, or Mute. You can mix the layers to create the ideal blend.
You can also adjust the balance between the DI box, amp mic, and room mic to shape the tone further.
The library features two playback modes (original attack/release or ADSR mode), five round robin layers, and some built-in effects, including EQ, reverb, compression, phaser, delay, and rotator.
You’ll also get seven factory presets to get you started.
Harmo is a cool way to add another type of tonal quality to your music without picking up a real guitar.
While some melodies built entirely on natural harmonics sound cool, it’s much more impactful when used tastefully in the right place. Or, as the developer suggests, as the foundation for a deeper sound design objective.
All in all, it is an interesting library, and as it is free, be sure to check it out.
Download: HARMO (FREE until September 4 – Native Instruments Kontakt version 6.4.2 or higher required)
