TubeOhm AlphaRay

This 10-voice VA synth is typical of some of the more recent hardware synth releases. With two oscillators, a sub and overdrive, you can get analogue bite and distortion, but it can be mellow too. It has a great look and atmospheric sounds.
There are plenty of controls and features, with optional effects (for €4.95). There’s a fantastic manual, full of all the tech specs and graphs.
