Efektor Omnivibe Optical Vibe Machine

Reviewed By Faydit [all]
March 19th, 2024
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.

Efektor Harmonitron

Version reviewed: 1.0 on Mac

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.

Efektor Harmonitron

Reviewed By Faydit [all]
January 30th, 2023
Version reviewed: 1 on Windows

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.

I personally feel this is the most versatile Amp sim Amplifikation has out there, I'm pretty sure I have all of their amp sims, and they all sound good....but this one......when I heard this one, it actually made me look up at it with eyebrows raised, this one is clearly, and audibly the best sounding Amp they have put out to date in my opinion, nothing else sounds like it, I literally have thousands of dollars invested in amp sims, and this one stands alone, out of all of the ones I own, it is the first one that has made me pause, and look up, and say wow......no kidding....check it out....I have no doubt you'll agree.

EVE-MP5 Equalizer

Reviewed By Scott L Wilson [all]
January 3rd, 2021
Version reviewed: 1.05 on Windows

Test driving this plug-in, I quickly appreciated the ability to add or subtract distortion by switching it on or off. This increased focus and adds a vintage vibe and roundness. I felt the MP5 has a clear sound even with extreme boost or cut. More important, the user interface is crisp and easy to see, as well as get around.

In terms of comparable analysis vs. a real hardware tube eq, I didn't have that opportunity. I would guess it is close with regard to the eq curves available but the anomolies of pure tube audio are very complex to model, even in 64-bit.

Overall, the MP5 does the job well. Thickening kick drums and bass guitar. Enhancing and scooping mids on guitars. Adding high frequency without harshness. All a win with this plug-in.

Would I use others, maybe. I will find many uses for it and the precision of the interface makes it fast and efficient.

Amplifikation Vermilion

Version reviewed: 1.1.3 on Mac

Kuassa's Amplifikation Vermillion is a great sounding emulation of a vintage tube combo amp. Rather than emulating a specific amp, Vermillion, to my ears, does a nice job with a range of clean to crunchy tones reminiscent of a lot of Fender tube combos. The clean tone sounds nice and crisp like a Fender which I like - I don't think it does the sterile clean of a JC-20 nor does it do the brash jangle of an AC-30, but if you like Fender deluxe reverbs or Rivera amps, you will like this plugin. The Spring reverb sounds nice, the tremelo sounds good and is sync-able. The more distorted presets also sound pretty good to me. My only gripe is that there is not a ton of tweakability between the presets - the gain knob and the eq knobs don't affect the tone as much as a real amp, so you really need to explore the presets to find a sound you like, rather than tweaking from scratch. That said, I do really like the sound of this amp, especially for 60's inspired tracks or cleaner post-punk and indie sounds.
