Tyrell Nexus 6

Tyrell Nexus 6 free software-synthesizer by u-he

Tyrell Nexus 6 is a free software synthesizer developed by u-he. Available format(s): VST, VST3, Audio Unit for Windows 64b, macOS.

The Tyrell Nexus 6 plug-in was programmed by Urs Heckmann (mastermind of u-he) for Amazona.de. This is a virtual analog software synthesizer: the sound engine is circuit-modeled and is similar to the u-he “ACE“. The features are those that we may expect from a vintage synthesizer like the Juno series from Roland.

Features:

  • 2 Oscillators.
  • 1 Sub-Oscillator.
  • 1 Noise Generator.
  • 1 Ring modulator.
  • 1 Signal feedback.
  • 2 LFOs.
  • 2 ADSR envelopes.
  • 1 Modulation Matrix.

Twin Bass

Twin Bass free software-synthesizer by The Interruptor

Twin Bass is a free software synthesizer developed by The Interruptor. Available format(s): VST for Windows.

Twin Bass is a Bass Synthesizer with a double filter architecture allowing to create rich mid-range bass textures together with a solid sub bass foundation. Also vocal-like timbres can be easily created. Features an extensive modulation matrix and individual outs for the filters.

  • 2 Oscillators: Sine, Saw, Ramp, Triangle, Pulse, Noise.
  • 2 Filters operating in parallel (connection in series is also possible).
    • Filter 1: 2 x Low pass, 2 x High pass, Bandpass.
    • Filter 2: stereo filter with separate cut-off for left and right side (2 x Low pass, 2 x High pass, Bandpass).
  • Feedback loop for the entire filter section.
  • Distortion effect with two modes
    • hard: metallic distortion sound.
    • soft: tube-like warm distortion.
  • The distortion effect can be applied pre- or post-filter. Also it is possible to distort only the signal in filter 2, thus preserving a clean signal from filter 1. This setup is predestined to generate a sub bass with filter 1 whereas filter 2 can provide interesting midrange textures in stereo.
  • Modulation
    • 3 x LFO, synchronized to host application.
    • 3 x ADSR Envelope.
    • Matrix: 5 modulation slots connect 12 modulation sources to 26 modulation destinations. Pitch bend, amplifier envelope and filter envelope are pre-wired.
  • Process external signals: In Oscillator 2 an external signal can be selected as the waveform.
  • MIDI learn: Right-click any control to assign a MIDI control and automate the parameter from you DAW.
  • Monophonic modes with glide.
  • Polyphonic modes with max. 8 simultaneous notes.
  • Individual Outs are available for the two Filters. This feature helps to integrate the bass sound in your mix. For example apply additional effects like reverb to the mid range signal from filter 2 while keeping the sub bass form filter 1 clean.
  • Structure display: This panel shows the signal flow of the synth as it results from your settings of the filter and FX routings.
  • Pop-up hints: While the mouse hovers over a control a hint appears explaining the function of the control.

Tunefish 4

Tunefish 4 free software-synthesizer by Brain Control

Tunefish 4 is a free software synthesizer developed by Brain Control. Available format(s): VST, VST3, Audio Unit for Windows 64b, macOS.

Tunefish 4 was developed as a smaller replacement of Tunefish 3 with roughly the same power, it is however not compatible and uses different synthesis algorithms. It was developed for the 64k intro “Turtles all the way down” by demoscene group Brain Control and is available as VST/AU.

Features:

  • Improved UI compared to TF3 which will visualize all modulations.
  • Uses an additive synthesis based wavetable generator.
  • The Noise generator can produce any frequency of noise with any bandwidth.
  • Lowpass, Highpass, Bandpass and an improved Notch filter are available.
  • 2 ADSRs and 2 LFOs that can be linked to pretty much any important knob using a modulation matrix.
  • Supported effects are Flanger, Chorus, Distortion, Delay, Reverb, EQ and Formant.
  • The effects stack allows for any permutation of up to 10 effects.

Tunefish 3

Tunefish 3 free software-synthesizer by Brain Control

Tunefish 3 is a free software synthesizer developed by Brain Control. Available format(s): VST, Audio Unit for Windows 64b, macOS.

Tunefish 3 is a tiny virtual analogue synth that was originally developed for the demo scene or, to be more precise, for 64k intros of the demo group Brain Control. The synth itself is developed to fit into 10kb of compressed machine code, but they have decided to release the larger VSTi version of it for free to the public. The synth is an ongoing project under active development and feedback is very welcome.

Features:

  • Implemented as a VST instrument.
  • It uses a spline based oscillator that can by configured very dynamically. Additionally to that, it contains an additive synth.
  • Additionally to normal sine, sawtooth, triangle and pulse waveforms, it can do anything that is possible with 6 points and step/linear/spline interpolation.
  • The Noise generator can produce any frequency of noise with any bandwidth.
  • Lowpass, Highpass, Bandpass and Notch filters are available.
  • 4 ADSRs and 4 LFOs that can be linked to pretty much any important knob using a modulation matrix.
  • Supported effects are Flanger, Chorus, Distortion, Delay, Reverb, EQ and Formant.
  • The effects stack allows for any permutation of up to 10 effects.

TS-Substance

TS-Substance free software-synthesizer by Tactile Sounds

TS-Substance is a free software synthesizer developed by Tactile Sounds. Available format(s): VST for Windows.

Substance is a virtual analog software synthesizer emphasizing simplicity, flexibility, and sound quality.

The key factors in the design of Substance were that it would sound great, without effects, and that it would fit on one page. Substance has two of everything: two oscillator sections, two LFOs, two envelopes, two filters.

The oscillator sections were inspired by the architecture of classic analog polysynths, which used multiple oscillators to achieve polyphony, but allowed the oscillators to be combined for a monophonic Unison mode. The oscillators would generally be slightly out of tune with one another, resulting in a rich, chorused sound. Each of Substance’s oscillators likewise comprises seven unison voices, with the amount of detuning, and the stereo breadth being addressed by a single parameter, Spread.

The LFOs can be used to modulate almost every parameter of the synth. They can be used to trigger the envelopes, to modulate the frequency and pulse-width of the oscillators, the cutoff frequency of the filters, and the volume of the amplifier. LFO-1 can be switched between free-running, tempo-synced, and key-synced modes.

A manual is included in the download link, detailing the other features. All parameters can be automated. Remote control is available via host mapping or MIDI learn.

Traveller

Traveller free software-synthesizer by Severák

Traveller is a free software synthesizer developed by Severák. Available format(s): VST for Windows.

Traveller is a monophonic synth inspired by Korg Synthe-Bass and its overall simplicity.

It features:

  • one oscillator with six different waveforms (two of these are actually PWM-modulated square and one is noise).
  • twisted monophony
  • traveller slider (filter cutoff).
  • slow/instant slider (attack time).
  • bump/singing slider (release time).
  • hold switch (sustain on/off).
  • bite switch (resonance on/off).
  • quack switch (filter follows envelope on/off).
  • and most importantly – volume knob.

The twist (in monophony) is that while you cannot hold two or more notes, you can hear previous note release while next one kicks in. This is actually implementation defect, but I left it as is because it adds character to the synth.

There are no presets as I believe limitations stimulates creativity but there is demo video to inspire you – {See video at top of page}

Good to know:

  • Don’t forget to unpack csound64.dll to plugin folder.
  • It’s open source – just open traveller.csd and examine or change code (refer to the Cabbage docs).
  • It has no velocity sensitivity, but tone depends on how long you hold the key (for tones with long attack).
  • You can use pitch bend wheel.

Note: Release 1.0 of this synth was broken. Now updated version was uploaded.
