VizualSynth

VizualSynth is a free VSTi synthesizer or SoftSynth.
You can also use it as a stand-alone instrument connected to a MIDI keyboard or sequencer and it will respond to the full range of MIDI commands. The real beauty of VizualSynth is that it is intended to teach you about things like envelope shaping and equalisation in an intuitive and visual way. You can see what your envelope and EQ shapes look like and use the mouse to alter them on-screen visually rather than just sliding controls up and down. click here to download now
