It's an old plugin. I know. But I've just found http://bserrano.free.fr and his VSTs. This one is a true masterpiece. Crispy clean sound. Easy to understand signal flow. GUI is also nice (although not according to the latest trends).
Now I´m mad, because after hour spent on this review when I submit it, I´m suddenly not logged in and the review is gone...OK, this will be brief now - apologies to author of the plugin.
After the last update, the glitch that was present in some presets is gone and that´s great, because now it sounds just fantastic - at least compared to most of the free FM synths.
Pristine sound and 128 presets full of FM plucks, organs, pads and sequences.
Pretty deep routing options - through main modulation matrix and voices-modulation matrix. 8 pages where you can play with voices settings / up to 256 harmonics / and waveform structures / lot´s of combinations /, DADSR amplitude envelopes, filters / 8 stage + injecting one into another /, fx / phaser-flanger, chorus, delay, 3-band resonators, static HPF /, keyboard settings / lowest-highest note, bender, retrigger /, envelopes / 8 segment graphical /, modulation and submodulation.
For automation you can use the per voice arpegiators and the step sequencer with host sync, semi-tones setting, coarse knobs.
That´s pretty just some of the functions, there is more of them and I would suggest: Go and try it and hear it for yourself.
And I shouldn´t forget the MIDI learn - one of my favourite functions, which is not so common in the freeware category.
GUI is clean / brushed metallic surface with green digits in the matrix / and the pages with controls are set pretty logically, so I didn´t have a problem understanding the synth even without the manual which is not included in the free version / there is only a brief desription on the web page /.
As for the support, I don´t need it and the synth is free so I don´t expect it, but that doesn´t mean there is not any – you can contact the author, so there must be some and as there was an update few days ago, there should be something going on there.
Value for money: It´s free and the Pro version is Donationware and for your donation you get more voices, vibrato control, manual, separate outputs, some more controls. So the value is 100% of the price and maybe even more!Read Review
Beware : Adonis 2.0 (of the present page) has been released AFTER Adonis Pro 1.6 and is more powerful than Adonis Pro 1.6. Both beeing freeware, Adonis Pro 1.6 must now be considered as an old version of Adonis 2.0.
So you don't need anymore to download Adonis Pro 1.6 but always only Adonis 2.0 of the present page.
