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.

3 oscillators.

2 ADSRs and 1 mod.

PolyGAS

PolyGAS is a free software synthesizer developed by Stone Voices. Available format(s): VST for Windows.

PolyGAS (Polyphonic Granular Advanced Synthesizer) is a free virtual synthesizer based on a granular method of sound synthesis.

Main features:

32-part polyphony.

Support of files of samples in the WAV and AIFF formats, digit capacity of 8,16,24 and 32-bits / sample, mono / stereo. Files are supported only uncompressed by codecs.

The editor of the bending parameters of granular synthesis. 18 envelopes with the maximum quantity of nodes – 40 (in each envelope). Also there is a tab where it is possible to edit dependence of amplitude of the clicked key bending from a tonality. There is a possibility of synchronization of provisional regulations of nodes of envelopes with rate of composition in DAW.

Controlled randomization of parameters of granular synthesis.

Amplitude non-linear distortions, with a possibility of a type selection (a clipping, bit-crusher, etc.) – only 11 types.

The controlled universal filter allowing as manual installation of frequency of a cutoff (Cutoff) and a resonance (Reson), and by means of envelopes. There is a mode in case of which the frequency of a cutoff depends on a tonality of the clicked key. In the filter different types of filtering (LP, HP, BP, Comb and Allpass), only 11 types are used.

The line of a time delay with modulation realizing effects of Delay and Flanger. There is a possibility of time synchronization of a time delay with rate of composition in DAW, and also the set modes of back coupling (Normal/CrossFeed) and the wave form of a modulating signal LFO (Sine/Triangle).

The reverberator creating high-quality spatial reverberation on Ambient Reverb Stone Voices technology.

The master the section including regulators of low and high frequencies, and also width of a stereobasis and the overall level.

The microtone setup using files of the VAZ/Anamark tuning format format (extension of *.tun and *.scl).

Tools for operation with banks and presets.

Support of MIDI controllers.

Poly 2106

Poly 2106 is a free software synthesizer developed by Synthescience. Available format(s): VST for Windows.

The Poly 2106 initially started off as a recreation of a true object of desire from the fashionable 80’s that was once part of our studio, but that was just the initial kick that propelled a seemingly more enthusiastic project which culminated into a knob infested creation with a solid vintage backbone. So for a long time we didn’t spare ourselves in the effort of breathing life into a machine which is a breed of everything we would like to see in a true performance synthesizer, something close to the vision of our personal nirvana that now we are ready to share to everyone, our only hope is that you too find it as much as rewarding as we did…
