Protoverb
Protoverb is a free reverb VST, Audio Unit, AAX plugin developed by u-he. Compatible OS(s): Windows, macOS.
Protoverb is an experimental reverb based on the idea of a “room simulator”.
This first version of Protoverb is released as a free “research-ware” plug-in, created to discover more about reverbs.
Most algorithmic reverbs try to avoid resonances or model the reflections of sound from a rooms walls. Protoverb does the opposite. It builds up as many room resonances as possible, modeling the body of air in the room. It therefore does not need to modulate or colour the signal. The result is a very natural sounding reverberation with some interesting features: Long standing frequencies resonate louder, as if the air takes some time to get excited. Multiple instruments don’t mash into a diffuse mudd, they stay distinct. If you play a short melody, the room seems to repeat a ghost echo of that melody. Those properties are indeed found in churches and large halls, but they’re rarely found in conventional algorithmic reverbs.
Protoverb has limited controls, with most parameters hidden from user control. There are 2 randomise buttons that modify these parameters to encourage user experimentation.

Proteus VX
Proteus VX is a free rompler VST plugin developed by E-MU. Compatible OS(s): Windows.
Proteus VX borrows its internal architecture from its big brother, Emulator X3. Although Proteus VX does not have the extensive editing capabilities of Emulator X3, it does offer 16 continuous controllers for each preset. The 16 controllers allow you to create subtle to radical transformations to the sounds, then save them with the bank.
The included v2.01 Proteus X Composer bank comes with over 1000 presets covering an immense range of sounds from the Proteus 2000 MIDI sound module. In addition, Proteus VX can load any sounds from the Emulator X library, as long as they can be loaded into system RAM (Sample-streaming not supported on Proteus VX).
Proteus VX is not copy protected or card locked like other versions of our instrument and sampling software, and can be used either as a VSTi or in stand-alone mode.
Features:
- 24-bit/192kHz audio playback.
- Can be used as VSTi or stand-alone (16 channel multi-timbral).
- Built-in 32-bit floating-point effects with 23 effects algorithms.
- High Voice Polyphony (system dependent).
- Drag and drop preset selection.
- Real-time controllers for all important control points.
- 54 different filter types including multi-pole resonant filters, phasers, flangers, vocal filters and multi-parameter morphing filters.
Note: Proteus VX tutorial support is not offered for this free download. Very limited technical support is available for basic setup and install issues. Proteus VX will install and function for most users under Windows Vista, but this product is only officially tested and supported for Windows XP.

PropheSea
PropheSea is a free software synthesizer developed by NOVUZEIT. Available format(s): VST for Windows.
PropheSea is a subtractive vector hybrid synth. It differs from most traditional vector synthesizers in that its waveforms are generated in real-time through subtractive synthesis, rather than being culled from pre-rendered ROM wave selection tables. The real-time waveform generators support a huge variety of internal manipulation.
PropheSea also has multiple LFOs, Additive Harmonic Feedback support, and a global FX section for mutating and sweetening the sound. PropheSea’s Dynamic Vector Control allows users to morph between the four waveform generators via their own hand, or through the use of computer automated vector sweeping.

Prophanity
Prophanity is a free software synthesizer developed by Roberson Audio Synthesizers. Available format(s): VST for Windows.
Prophanity is an emulation of a Sequential Circuits Prophet 5. Much time was given for attention to detail in nearly every aspect of the instrument, and most every subtlety has been accounted for.

ProjectX1
ProjectX1 is a free software synthesizer developed by JC Productionz. Available format(s): VST for Windows.
ProjectX1 is a hybrid bass synth featuring urban type bass sounds utilizing subtractive, FM and phase distortion synthesis.
ProjectX1 is essentially a monophonic synth but also has a pseudo stereo mode and features 3 oscillators, osc sync, 2 filters, LFO, 2 ADSRs, mod envelope generator, 2 waveshapers, tube amp and bit crusher effects, 2 modulation matrixes with 24 possible destinations with the option of signal inversion. The phase distortion osc has 2 wave generators each comprising of 8 waveforms, and the FM osc comes with 7 standard waveforms and also has a sync mode. There’s an add-on unison oscillator which includes 3 waveforms.
Each oscillator has fine tune and transpose functions and the synth also has a master fine tune control. There are 3 main modes of operation which are FM, phase distortion and FM+phase distortion with a mix knob to get more level from either oscillator. The first filter has Low Pass or HP operation and has an analog/digital emulator, bass boost, Q tap and clear/furry options; the 2nd filter acts more like a basic eq and is in a fixed mode of operation.
You can view your sounds/waveforms via the frequency analyser or onboard scope. In pseudo stereo mode you can control left and right levels via separate sliders in the master section in the top left of the synth; also in this section there is retrigger, velocity switch, master level and glide. The included LFO is host synced and doesn’t operate in free mode. The tube amp has adjustable clipping hardness, bias, and power supply regulation, clipping and/or crossover distortion. Most of the parameters on this synth can be automated via MIDI or your host automation.
Features:
- 3 oscillators.
- 2 ADSRs and 1 mod.
- Frequency analyser & scope.
- Mono/pseudo stereo mode.
- Host synced LFO.
- 2 modulation matrixes with 24 destinations each.
- Peak follower.
- Dual waveshapers.
- 2 filters.
- Soft/hard clipping.
- Tube amp simulation.
- Bit crusher.
- 3 oscillator modes.
- Automation via MIDI or host.
- 25 presets.
- Preset display.
- Global fine tune.
