A free polyphonic musical synth with lots of modulation: http://tytel.org/helm

Helm is a free, cross-platform, polyphonic synthesizer that runs on GNU/Linux, Mac, and Windows as a standalone program and as a LV2/VST/AU/AAX plugin. Release is in beta so there are outstanding bugs. Please send any bugs found to matthewtytel@gmail.com

The main goals of Helm are ease of use and software freedom. A lot of development has been focused on creating nice graphical widgets so you can see what's going on. It's licensed under GPLv3 so it's free to use/distribute/change and all that.
