Another great review on KVR by user jodejo:

Read Astralis Review on KVR

"Currently Astralis is compose by three synths: Astralis A, B and C (still in beta version at this time). Astralis A and B are waveforms based synths with various possibilities (see main features) concerning effects, modulations options, routing and to handle waveforms. It's simple you can do all you want with waveforms and create your own sound easily (bass, rythmic sounds, pads, athmospheres). All these sounds are moving wich is perfect for soundscapes. Astralis B is the same but with reduced cpu. That's great with Astralis A to produce sounds with more space.

Astralis C is a sample based synth. It's a beta version at this time but works very well and increase greatly the possibilities. To summarize, the Astralis pack is a real quality sound factory : almost all sounds can be created and give a total control on these sounds. And in this point of view it offer me more that I expected."
