Amazona.de has announced the release of Tyrell Nexus 6, a new free plug-in that was programmed by Urs Heckmann (mastermind of u-he) for Amazona.de.
Tyrell Nexus 6 is a virtual analog software synthesizer: the sound engine is circuit-modeled and is similar to the u-he "ACE". The features are those that we may expect from a vintage synthesizer like the Juno series from Roland.
Features:
2 Oscillators.
1 Sub-Oscillator.
1 Noise Generator.
1 Ring modulator.
1 Signal feedback.
2 LFOs.
2 ADSR envelopes.
1 Modulation Matrix.
Pricing & Availability
Tyrell Nexus 6 is free and is available for Windows, Windows x64 and Mac OS X as VST and AU instrument plug-ins.

If it sounds as good as ACE does, this is a really sweet deal. Also super easy to program...one screen, simple interface.
