R2

R2 free software-synthesizer by KlangLabs

R2 is a free software synthesizer developed by KlangLabs. Available format(s): VST for Windows 64b.

R2 is a hybrid synth and effect processor, just assign a MIDI track to it to play notes and use an external source (preferably voice) to make the pitch change. You can achieve interesting sounds with this plug, besides the famous Star Wars R2-D2 blips you can use it as a synth and use your voice to make weird vibratos.

PUSH

PUSH free software-synthesizer by Sampleson

PUSH is a free software synthesizer developed by Sampleson. Available format(s): VST, Audio Unit for Windows, macOS.

PUSH. ONE BUTTON SYNTHESIZER.

Push is a generative synth sound module (and it’s free). It will create a new patch every single time you hit that button in the middle. Edit panel will allow you to fine-tune sounds. It’s free for every one, you grab your copy here

ONE BUTTON. A LOT OF LOGIC.

Push is a subtractive synth with a huge amount of randomness. Parametrized with a sound-design logic to get the most of the results to be usable as a patch. All of the randomized parameters are accessible via the “Edit Current” button.

You can use the patches as they are once you press the push button, or you can use the initial patch as inspiration to tweak each sound into a new and refined one.

Resulting patches and banks can be exported and shared without limits. Just click on “Open/Save” then “More” and “Export Bank” to get a shareable file.

Punish

Punish free multi-fx by Heavyocity

Punish is a free multi fx VST, VST3, Audio Unit, AAX plugin developed by Heavyocity. Compatible OS(s): Windows 64b, macOS.

From subtle warmth to extreme drive and compression, PUNISH injects character and edge into any mix or instrument track. It’s the same PUNISH effect that you know and love, as featured in Heavyocity’s award-winning line of virtual instruments, now in VST/AU/AAX plugin format. Modeled after Heavyocity’s custom analog signal chains, PUNISH gives you control over Compression, Saturation, Transients, EQ, and Limiting. Chain the modules together to get that signature PUNISH sound, or isolate them to experience each dynamic effect on its own.

And at the heart of it all is the global PUNISH Knob. Simply set your ranges, and use the one knob to dial in the devastation.

Compression / Saturation

With three distinct compression models, the PUNISH Compressor offers a wide dynamic range, topped off with that classic analog warmth. The plugin features a smooth Class A-style Buss Compressor (Console), an aggressive, fat sound with a classic “knee” (Modern), and a warm vintage limiting amplifier-style (Classic).

The PUNISH Saturation module also features three different models, all with their own unique brand of warmth, drive, and character. With a classic broadcast mic-pre (Vintage), a chunky harmonic saturation (Modern), and a fat tube saturation (Tube), the PUNISH Saturation module can add a bit of grit to a track, or drive the whole thing into overload.

Transients / EQ / Limiting

Providing control over the attack, sustain, and output gain, PUNISH‘s Transient shaping module brings stronger transients back into the signal after saturating the sound. The module also features Hold control to determine length of the attack.

The EQ module is basic but powerful, offering lift of the high and low frequencies. Set the EQ to Pre or Post to affect highs and lows before the Comp, Sat, and Transient…or after.

To prevent clipping, PUNISH also features a Limiter at the end of the chain. Soft clip amount and release time controls are key, when that Saturation starts to get things truly hairy.

PULS

PULS free software-synthesizer by de la Mancha

PULS is a free software synthesizer developed by de la Mancha. Available format(s): VST for Windows.

PULS is a monophonic pulse wave synthesizer with simple controls but complex sounds. From two pulse wave oscillators you can get chunky basses, scorching leads, retro chiptune, dusty lofi and oddball noises. With an unusual isometric pixel-art interface, what it lacks in knobs, it makes up for in sound.

It features custom pulse waveforms, unison, oscillator sync and ring modulation for some big ‘n’ dirty sound potential, with a tempo-sync LFO for pulse width modulation (PWM) as well as detune and volume modulation.

Features:

  • Monophonic pulse wave synthesizer.
  • 2 oscillators with custom pulse waveforms:
    • Adjustable Pulse width, modulated by LFO (per osc).
    • Unison per oscillator.
    • Oscillator sync and ring modulation between oscillators.
  • Adjustable non-linear Release.
  • Tempo-sync LFO with 4 waveforms with adjustable speed and depth:
    • Pulse width modulation per oscillator.
    • Detune and volume modulation.
  • Tempo-sync arpeggiator with 6 patterns:
    • Arp can cover 1 to 4 octaves, synced to host (1/32 beats to 4 beats).
    • Adjustable note length (0-100%).
  • 32 presets covering different styles and functions.

psymon

psymon free software-synthesizer by de la Mancha

psymon is a free software synthesizer developed by de la Mancha. Available format(s): VST for Windows.

psymon is a single-waveform, retro, lofi noise maker.

Whilst faithfully recreating the ‘speaker in a box’ sound of the original game, psymon takes a bold leap into the 21st century. You are no longer limited to the 4 notes of the game, but can use every single note on your MIDI keyboard. With a simple press of the keyboard icon you can bring modern technology to bear and have each note sustain whilst your MIDI key is pressed. Not only that, but the notes become velocity sensitive too.

Features:

  • One waveform.
  • One preset.
  • Optional note sustain and velocity.
