Braindoc has released a public beta of Amplitude Modulator, a freeware amplitude modulation (envelope/LFO/gate) plug-in for Windows.

Amplitude Modulator requires MIDI-input:

• On note-on, the modulation generator starts at time zero. When the note is being held, it will run into a loop, wich is determined by the two locators. This results in a generalized sustain in terms of the ADSR-model
• On note-off, it leaves the loop and runs through the part behind the loop-end locator. This can be seen as generalized release
• When it reaches its end-point, it will stay at this level until a new note-on comes in
• Neither start- nor end-point are fixed at zero level, they can have any value - if you adjust them to unity level, the output amplitude will be unaffected, when no note is being played
• When you have them at zero (as in the screenshot), output will be silent, when no note is being played
