Efektor Filtrator Modulated Filter

Reviewed By Faydit [all]
November 24th, 2024
Version reviewed: 1.0 on Windows

Interesting, unique pedal, if you look for some different sounds from your guitar. Reminds me of some analog synthesizers from the 1970's in a positive way. A lot of different sounds adjustable, nevertheless would be even better, if this plugin offered a more flexible, variable midi-expression-pedal controllable Rate/Depth adjustment too.

Nevertheless sounds nice even standalone, in combination with an amp plugin but also eg. in combination with an octaver or pitch shifter/harmonizer plugin or other effects. You can get some nice, simple, but real-time polyphonic "fake-synthesizer" sounds out of a guitar, and with the mixing options you can use them alone or in combination with the tone of your other gear too and this without any latency issues or additional hard- or software.

If you like the sounds, is a matter of taste, but in principle the pugin is well made and sounds good and different. Also well usable for different, additional synthesizer/keyboard voicings, for bass anyway, maybe even for drums/percussion or some strange vocals with certain settings.

Worth a try in my opinion. At the moment a bargain too.

This is a very basic, simple delay. It works. I got it for free as a loyalty gift from an online seller and added it to my growing list of very basic, single purpose plugins.

Efektor Omnivibe Optical Vibe Machine

Version reviewed: 1.0.0 on Windows

Nice, much more flexible adjustable Univibe based plugin, which also allows some more or less differently voiced sounds in comparison with the original, while on the other hand adjusting a really authentic sound can become a little more complicated.

I personally like it, especially for creating some more unusual sounds.

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.

Efektor Harmonitron

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.
