Rawvoltage offers its entire plugin range as a free download with optional donations.
In the mood for some free stuff? I can hear you groan as you make space in your plugin folder but don’t worry; I’m right there with you.
RAWVOLTAGE has set its entire plugin library free. We don’t know the reason for this change, but we hope it doesn’t mean that the developer is going out of business.
Users are encouraged to make donations if possible. Whether or not you donate, three free instruments and three effects are available for your perusal.
Glory is first up on our list. It is a subtractive synthesizer with a host of features. You get access to analog-modeled oscillators, a sub-oscillator, a transient oscillator, and an arpeggiator, among other features.
Also available for Glory is a smattering of free soundbanks if you’re not in the mood for sound design. These range over a wide variety of genres.
W-77 is a decidedly more vintage style of subtractive synth and is strictly monophonic in concept.
This one has three oscillator waveforms, an automatic LFO, and a quick and easy workflow. The only free soundbank available are the factory presets, but the synth can put in some work if you’re after a little bit of that Tangerine Dream feel.

The final instrument is Bad Contact, which is more test equipment than an instrument. It generates sounds that you can manipulate and make sound more or less lo-fi. Not super usable in production, but it is great for sampling purposes.
As for the effects, you can download FX Box, PMP, and Mask Off for free from Rawvoltage.
FX Box is the effects section of Glory but as a standalone package. PMP gives you that wonderful pumping sound you get with sidechain compression. Mask Off is a voice cleaner for streaming live audio, intended to help rich sound from dull sound sources.
FX Box, in particular, is a fun one and carries across the admittedly solid effects section to be used on other synths and sound sources.
These are, unfortunately, Windows-only VST plugins at the time of this writing. Donation information and sound demos, manuals, and other documentation are directly available on the developer’s website.
