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.
