Ilir lluka has released Lyre, free VST/standalone polyphonic synthesizer for Windows.
Compatible with every DAW on the market.
The vst version does not contain the reverb and compresor / expander modules, however this was done to ease the cpu work since _Lyre requires some good amount of it. However _compEx is included as a separate plugin in the bundle so you can use it in chain along the signal path of _Lyre as well as any other third party plugin you already have combined for your needs.
To use Lyre just place the .dll file into the vst folder of your host.
