Introducing Kuassa Efektor Harmonitron – the ultimate pitch shifting and harmonizing tool for sound designers and music producers. Unleash the power of pitch manipulation to add depth and dimension to your soundscapes. With the ability to add extra low-fatness and detune to thicken your riffs, rise different pitch notes to enrich your vocals, or use the swell (slow attack) feature to create an organ or synth-like tone with your guitar.

For decades, the harmonizing pedal effect is used by some of the most renowned artists in the industry, such as The Beatles*, Tom Morello*, Prince*, and Jack White*. It's also a favorite among goregrind and death metal bands for creating guttural, unnaturally low vocals.

Each slider transposes the pitch up or down in a range from -24 to +24 semitones (-/+ 2 octaves) with +/- 50 cents global detune effects. Featuring quad independent pitch shifting engines with detune, swell, and low-pass filter options, Efektor Harmonitron is a cutting-edge, new product that sets itself apart from any other pitch shifting and harmonizing guitar effect pedal software on the market. It offers a unique set of features, unmatched precision and flexibility that you won't find in any other product, making it the go-to choice for sound designers and music producers who want to take their sound to the next level.

Whether you're a professional sound designer or a music producer, Efektor Harmonitron is the essential tool to take your sound to the next level. Don't miss out, order yours today and elevate your sound game.

Key Features:

  • Quad engine polyphonic pitch shifting.
  • 24 to +24 semitones.

Amazing plugin! Easy to use, great sound and it really re-sparked my creativity. It made me feel like I was rediscovering my guitar. I highly recommnd the Efektor Harmonitron. For the price, you get a whole much more than what you pay. There's so much to explore and the sound is incredible. The presets make it easy to get started but then you can take control and customize your own settings. This is an absolute gem. Thank you thank you thank you for this must have creative tool and fun plugin.

Kozmik Wave.

Nice, obviously at least visually POG 2 octaver based plugin, but also with additional, rather with a Whammy/ Pitch Fork associated harmonizing features, so it is a quad octaver / quad harmonizer. You can adjust the interval of any of the four sliders individually to every posssible combination. If all posssible options sound good, is another theme, but good, that you have the choice to create also some strange harmonizations.

Another positive aspect is the low latency, processing works more or less in real time, which is not always the case with all octavers / pitch shifters, which I know.

As most harmonizers / pitch shifters / octavers it still sounds a little too synthetic for my taste, but, as the plugin anyway is no 100% copy of the original pedal, I think, it also could have been possible to add some additional sound shaping options for the anyway already synthesized harmonizer/octaver tones. At least an additional HP filter and a ADSR control would have been nice, maybe even more shaping and filtering options.

(One of my favorite real octaver pedals can even sound similar to a Hammond, which is really great and also a lot of fun, if your guitar suddenly sounds like Jon Lord. Unfortunately I did not find any octaver plugin up to now, which gives me comparable tones.).

The synthesization in principle works good, so with some additional features this also could become a nice, even more flexible audio signal triggered guitar/bass synthesizer, I think. (Not everybody has a guitar/bass to MIDI solution or likes to use one, so this could fill a gap in my opinion for guitar/bass players, who look for some different sounds.).

The harmonizations work chromatic, as far as I can see, so adding some key/scale based harmonizing options in a future upgrade could be a good idea, I think, as other harmonizers - like eg. even my favorite freeware pitch-shifter / harmonizer up to now - also offer this option too and this since years. But it unfortunately can only create a single harmonized voice, while the Harmonitron can create up to four, which enables even more complex sounds.

As it is, you nevertheless can get some very good sounding results, especially the Sweep and Detune controls are nice, useful tools. Also the fact, that the plugins works polyphonic is an advantage.

Still could be improved for my taste, but nevertheless a good tool for some more unusual guitar or bass sounds, but the plugin also is nicely usable for eg. keyboards and synthesizers. (I get really awesome sounds eg. with a Taurus or MiniMoog, but not only with them).

Therefore, despite my comments and complaints, five stars.
