Be warned, this is only my second review. Here goes.
User Interface- The GUI is well laid out and easy to understand. Various output analyzers provide handy visual displays of pre-filter and filter output intensity. Vector position points on a vector grid also provide GUI movement. A nice compromise between visual aides and functionality has been struck, eye candy without being obnoxious.
Sound- Aethereal, as the name implies, can sound very light and airy as well as heavenly. Think bright, evolving sounds full of movement. Like it says on the box, this is an ambient synth for textures and atmospheres. Credits mention samples provided by Les Productions Zvon and Claire Fitch.
Features- A much more flexible synth than I had initially realized, various tools make it relatively easy to create, sculpt and manipulate unique sounds. Four wave oscillators, a 4-Way TransMixer, a Multi-Vector (using three X/Y Position Points) and a 16-step mod sequencer are just some of those above mentioned tools.
To borrow from the website, "All of this along with two multi-stage filters, a dual delay, three modulation envelopes and assignable modwheel and pitchbender make Aethereal a very flexible and expressive ambient synthesizer with many possibilities.".
Documentation- The .html manual is nothing special. It describes all the synths features, lets the user know what all the buttons do and includes a MIDI chart.
Presets- 64 presets are included, most are quite impressive. They are definitely a good starting point, though some stand on their own without any tweaking.
Customer Support- Never had need for support, but Psychic Modulation does maintain a forum here at KVR.
Value for Money- An excellent value, the synth is also available as part of the Neurosynth Pack.
Stability- Very, very stable. When I use this synth I expect certain sounds and it delivers them.
I really enjoy Aethereal, I use it often and look forward to using it for a long time to come. Check out Psychic Modulation, I doubt you'll be disappointed.
