SynthTrack

SynthTrack is a free filter VST plugin developed by 2Rule. Compatible OS(s): Windows, macOS.

SynthTrack is a rhythmic effect plugin that uses track audio as a source. Applied to audio tracks (chords, vocals etc..), this plugin makes Filter/Amp ADSR and LFO effects triggered by 16 step sequencer pattern. With this effect, you can change rhythmic characteristic of the wave in the track. It’s suitable for creating typical rhythmic gated pad sounds. With the envelope controlled step sequencer, it’s possible to turn your pad sound into an arp-like sequence.
This plugin can be synchronized to the host sequencer / DAW tempo when available.

Demos.

Features:

16 steps per pattern.

Host tempo synchronization (where available).

HP BP LP Filter.

ADSR for Amplitude.

ADSR for Filter.

LFO Sinus Square-Saw waves, tempo-synchronized.

Push for button for one shot gate.

26 Presets.

SynthTest

SynthTest is a free routing plugin developed by Creed. Compatible OS(s): macOS.

SynthTest is a simple application for OS X that allows you to pick a MIDI source, a MusicDevice AudioUnit and an Effect or MusicEffect AudioUnit to play with. You can open an edit window for both the synth and effect. If they do not have a custom edit GUI, the generic editor view will be used.

It is primarily intended to be used by Audio Unit developers for testing purposes, although it can be fun to play with all by itself. In the end, I would like SynthTest to become an open reference implementation of an AudioUnit host.

Synthetik

Synthetik is a free software synthesizer developed by Tru-Urban. Available format(s): VST, VST3, Audio Unit for Windows 64b, macOS.

Synthetik is a free VST and AU plugin delivering fresh inspiring sounds and FX for Hip-Hop and R&B productions including synths, bells, synth bass, brass, electric pianos, pads, strings and more.

The Synthetik VST/AU Plugin is called a “semi-synth” because it does not posses all of the traditional functions of a full synthesizer. Instead, Synthetik has really high quality sounds out of the box that can be fine-tuned and tweaked further using the LFO settings, Reverb and ADSR. Synthetik has glide control and the full range of play modes such as Mono, Poly and Legato.

Synthetik is compatible with all music software supporting VST or AU format on both Windows and Mac.

SyncSawSynth

SyncSawSynth is a free software synthesizer developed by Uhhyou. Available format(s): VST3 for Windows 64b, macOS, Linux.

Note: Currently Linux build doesn’t display GUI due to some problem related to VSTGUI. For Linux, LV2 version is available at https://github.com/ryukau/LV2Plugins.

Note: I don’t have mac so macOS build is not tested. If you find bug, please report it to https://github.com/ryukau/VSTPlugins.

SyncSawSynth is a synthesizer equipped with up to 10th order PTR sawtooth oscillator. PTR stands for polynomial transition regions which is an aliasing suppressing technique. As the name suggests, this one hard syncs:

Equipped with 2 of 0 to 10th order PTR sawtooth oscillator.

Can also use sin. However, hard sync for sin is not alias suppressed.

3 types of hard sync option. Only use “Ratio” option for tonal sound.

Phase controls. Possible to make a square wave with phase inversion.

Frequency modulation between 2 oscillators. You can be a noise musician in a second.

1 AD envelope, 1 sin LFO and 1 pink noise generator for frequency modulation. The AD envelope uses equation (t^a * exp(-b * t)).

Exponential ADSR envelope saturated with tanh for output gain.

Equipped a filter that is serially connected 4 RBJ biquad with feedback. Low-pass, high-pass, band-pass, notch can be used.

4 types of filter feedback saturation.

Linear ADSR envelope for filter cutoff and resonance. The output of filter envelope is logarithmically mapped to cutoff frequency.

Key follow for filter cutoff and resonance.

Some optimization made into version 0.1.3, however it’s still a bit slow. To keep CPU consumption lower, reduce maximum number of voice.

Synchron Player

Synchron Player is a free rompler VST, Audio Unit, AAX plugin developed by Vienna Symphonic Library (VSL). Compatible OS(s): Windows, macOS.

The Vienna Synchron Player is a dedicated sample player with an audio engine built from the ground up. Combining multiple microphone signals with a wealth of note variations and velocity layers for each articulation may quickly lead to a quite heavy voice count and CPU load. The Vienna Synchron Player comes with the most powerful sample playback engine, featuring unprecedented streaming performance while providing a new level of ease-of-use.

Innovative algorithms result in utmost realism and expressiveness: You may play short notes, long notes with various attacks, legatos, scalable vibrato intensities and note repetitions intuitively just by moving one or two preconfigured controllers, with a minimal need to switch articulations manually. The Vienna Synchron Player also includes a full fledged internal mixer with 5-band EQ, individual delay settings for runtime compensation, algorithmic reverb, phase switching, panorama controls as well as a host of effects such as saturation, delay, compressor, auto gain and many more.

The Vienna Synchron Player is included as free software with all Synchron Series products, the Vienna Smart Orchestra and Vienna Smart Spheres.

8-dimensional Synchron Player
The one and only sample player on the market with eight or even unlimited dimensions. Dimensions allow you to add any freely controllable musical parameter to any Synchron Series preset, resulting in incomparable versatility.

Streaming Performance
The look-up-function is up to 32 times faster than with conventional sample players. This improved look-up function is the backbone of the Synchron Player’s unrivaled multi-microphone performance. All samples are linked to their corresponding microphone positions which improves access-times dramatically and allows for minimal latency. Up to 31 microphone channels (Synchron FX Strings I) provide infinite options to create a unique sound.

Out of the Box
Tailor-made mixer presets – ready to play. Easy access to authentic room impressions of Synchron Stage Vienna – from close to distant microphone positions.

Inspiring Elements
The new Synchron Player offers an intuitive work-flow for epic masterpieces and delicate soundscapes. Simple navigation: Instrument presets with consistent structure throughout all instruments will boost your creativity.
