EFM releases Micro Modular v0.6 VSTi
This synth is capable of creating some nice analog type sounds and includes a Mod Matrix and Chrorus, Delay and Arp controls.
There are only 16 presets included with Micro Modular but the layout of this synth is pretty intuitive and it should take little time coming up with a bunch of nice presets yourself.
Go check it out at EFM’s website.
