Strings Dream Synthesizer

Strings Dream Synthesizer is a free software synthesizer developed by NUSofting. Available format(s): VST for Windows.

[update beta5m August 6th 2019]

Public Beta, free to download, time limited at 15 minutes per session.

– VST2 64-bit for Windows* (and soon also VST2 for Mac).

– Brand new control for waveshape morphing.

– Extra sound engine for the paraphonic mode (“Paraphony” on GUI)
with new timbral characteristics, featuring “analogue pulsed noise” emulation.

– The paraphonic mode allows very different articulations
compared to the standard polyphonic mode (“Polyphony” on GUI).

– As per above, “Polyphony” vs “Paraphony” is now not just a change of behaviour
of the ADSR envelope.

– Redesigned filters for the voice stops, especially for the ones labeled “Brass” and “Horn”.

– Recalibrated relative gains of all the voice stops.

– “Ensemble” chorus DSP upgraded to higher order interpolation (improved transparency and warmth).

– Rewritten “Spring” algorithm for Reverb, to allow longer resonances.

– Reviewed all presets/patches.

– Analogue Drum Kit: bonus feature: 20 of the best LoFi sounds from Drum Machines* of the late Seventies.
(playable using the MIDI keys above the Strings sound range)

– Minor changes in the GUI and other minor bugs fixed. Larger GUI also available.
Three skins included. User can easily make custom skins by making PNG files.

– Everything that was already good in 1.x has been kept.
(Presets previously made for SDS 1.x needs to be adjusted when loaded in SDS 2.0)

*Formats: 32-bit VST2 will be delivered on customer request.
SDS AU for macOS will be produced after at least 100 requests.

*Drum Machines samples from NUSofting DK+ Library.
MIDI keys range: note 92 to 111. Volume controlled by MIDI Velocity.
[note: this is just a bonus feature for SDS, if you are interested in a true
Analogue Drum Set VST plugin to be release please let me know].

Things you NEED to know to fully enjoy Strings Dream Synthesizer:
1) The ranges of the stops/registers, by checking the SDS help docs.
2) Cello and C.Bass voices are monophonic and can be played in legato
at the same time of the polyphonic main voices.
3) A hidden bonus feature is the 20 sounds Analogue Drum Kit, playable with the top range MIDI notes.

Strings Dream Synthesizer is able to reproduce the infinite array of rich, analogue pads from the most famous strings machines in synthesizer history – emulating the classic Eminent Solina as well as its sister keyboards from Elka, Crumar and even their Japanese cousins.

Strings Dream Synthesizer does not use samples. Instead the “octave divider” circuitry typical of those early polyphonic synths has been natively emulated, so that all sounds are computed in realtime in true VA fashion.

The fundamental “Ensemble” effect (like the vintage Solina chorus) accurately follows the architecture of its hardware counterpart, including the BBD chip behaviour for truly rich modulation. However, it has been extended for a wider range of “chorus” effects.

Strings Dream Synthesizer is easy to use. Its layout and features take their cue from and expand upon the familiar Solina design, with only the necessary controls to achieve the textures of the other strings machines.

Main Features:

“True analogue sound”, VA “Octave Divider” emulation, (no samples used).

43 voices full polyphony, plus mono legato on bass section.

Vintage audio effects on board.

MIDI learn on every knob.

3 skins included.

Plus:

A full ADSR envelope generator and Waveform selection (for several strings and organs sounds).

Volume fader and switch for each of 6 stops (C.Bass, Cello, Brass, Horn, Viola and Violin). The fader for each stop allows an almost infinite number of mixtures.

A powerful parameter to tune the relative phase of Violin wave against the other voices.

Brightness and highpass filters are also adjustable.

More performance flexibility with MIDI velocity and polyphonic mode selectable.

Note also that the C.Bass and Cello are monophonic with full legato mode and you can select one of eight keyboard split points, allowing you to layer the mono voices with the others.

Chorus “Ensemble” effect with “Bucket-brigade device” tone.

Four-stage Phaser for those famous “Jarre pads” and other Tangerine Dream sounds.

Exclusive reverb with the ability to morph on request to that “trembling” sound of the vintage spring reverb units.

SQ8L / SQ8X

SQ8L / SQ8X is a free software synthesizer developed by Siegfried Kullmann. Available format(s): VST for Windows.

SQ8L is a software model of Ensoniq’s classic 1980s synth SQ80. The SQ80 features 3 digital wavetable oscillators for each of its 8 voices which are fed through analog 4-pole lowpass filters (-24dB gain) with resonance. Sound parameters can be modulated by 4 envelopes, 3 LFOs and several MIDI sources. The SQ80 also has a predecessor, the ESQ1, which can do most of the same stuff.

Although the technology may seem obsolete, these synths can produce a wide variety of interesting and extremely usable sounds. Thanks to the lo-fi oscillators and the analog components it can sound very digital and dirty, but also very analog and warm. Which is a good thing because modern synths often tend to sound rather clean.

The SQ8L (“L” stands for “Light”) is the free demo version of the forthcoming SQ8X (“X” for “eXtended”). Besides any bugs that will be fixed in the full version and planned features that won’t find their way into the light version, there are only a few limitations:

Polyphony limited to 8 voices.

Program change messages ignored.

Common MIDI controllers (Master Volume, Pan,…) by default have no effect and must be programmed as modulators.

When used with a sequencer, the only sound the host can save within the song file is the one in the edit buffer. The full version will store the entire library (which makes sense when program change messages are used).

LFO humanization not implemented.

No Split/Layer to combine several sounds.

No internal sequencer (and there will never be one).

The full version SQ8X will have the following additional features:

Combinations of up to 4 single sounds.

Adjustable polyphony (far more than 8 voices).

New Filter algorithms with different modes (lowpass, bandpass, highpass).

2nd Filter and different routing modes for the filters: serial, parallel, split.

Improved GUI.

Sonata

Sonata is a free software synthesizer developed by SoHa Sound Design. Available format(s): VST for Windows.

Sonata is a VST soft-synth for strong single-shot leads and pads. The distinctive character of Sonata makes it adept at strings and lots of simple subtractive sounds, while also specializing in sparkly and glassy mallet sounds, deep basses, and warm and rich mid-range chromatic inventions.

Sonata features two separate but similarly controlled generators, one for the sound’s immediate attack and another for the fundamental tone. Both consist of rich harmonic spectra which are filtered to provide desired overtones. Each possesses its own exponential decay envelopes for amplitude and filter, and its own ADSR envelope.

The output from these is then fed into a little black box—a complex setup of delay devices set relatively for each note that creates a complex comb-filtering effect. This stage shapes the sound, emphasizing desired frequencies and providing richer post-filter overtones, similar to the way an instrument’s body will influence its sound.

There are three global effects: a cross delay, distortion, and a reverb.

SoftAmp GT

SoftAmp GT is a free amp simulator VST plugin developed by AXP. Compatible OS(s): Windows.

SoftAmp GT is a virtual emulation of a well-known analog guitar amplifier simulator stomp-box. The prototype is a solid state circuit that uses op-amps to saturate the signal and moderate filtering to shape the tone throughout the signal path. The speaker simulation is achieved by a steep low-pass filter as well as some middle-frequency manipulation to resemble different microphone positions. All controls of the original device are faithfully reproduced in this plug-in in addition to some unique ones described below.

AMP – general amplifier family:

Tweed – classic American clean-sound amps.

British – crunch and moderate gain.

California – modern hi-gain amp with a deep low-end.

MOD – gain structure of the amplifier:

Clean.

Hi-gain.

Hot wired (same as hi-gain but with a high-freq boost).

MIC – virtual microphone position:

Classic – far from the speaker.

Center – the most bright setting.

Off-axis – slightly offset microphone that provides smoothed high-freq response.

The original stomp-box was somewhat criticized for having a symmetrical hard-clipping saturation and there were a lot of attempts to modify the circuit to provide smoother tube-like sound by the community. Variations included using different op-amps and using a bipolar transistor to introduce the asymmetrical clipping. This plug-in takes this concept further by introducing a special control:

CLIP – clipping mode:

Normal – standard hard-clipping modeled after the TLC2262 op-amp.

Soft – abstract symmetric soft-clipping stage.

Triode – virtual 12AU7 triode stage.

The most interesting is the Triode setting. It effectively replaces every op-amp in the circuit with a triode stage accurately modeled using the same engine used in the SoftAmp 3OD plug-in. It will perform asymmetric soft-cliping with dynamic behaviour that depends on the tube overdrive level that will produce a moderate amount of even harmonics. The overall difference is subtle, but it’s there. A good test would be listening to the effect applied to the sinusoidal input.

Another option is a very efficient 16x oversampling that has a non-obvious side-effect in addition to its main purpose (getting rid of the aliasing caused by the highly nonlinear distortion). Since the filters in this plug-in are digitized using the bilinear transform they exhibit a degrading matching with the analog prototypes with the frequencies approaching the Nyquist limit. Oversampling effectively shifts this frequency out of the sonic range thus greatly improving the filters’ performance at the sampling rates below or equal to 48000Hz.

SoftAmp GT also allows you to disable the embedded speaker simulation, so you can use your favourite speaker simulator plug-in with good impulses.

The last feature is the mono/stereo switch. It allows you to cut the CPU consumption in half when you don’t need both channels.

The GUI includes transfer function scopes for the three main clipping stages (there are more, but they are mostly operating in the linear range). There’s also a bode plot for pre- and post-filters, including the speaker simulation frequency response.

There are a number of presets that provide you a good starting point to experiment with this plug-in.

SoftAmp 3OD

SoftAmp 3OD is a free amp simulator VST plugin developed by AXP. Compatible OS(s): Windows.

AXP SoftAmp 3OD
Vacuum Triode Stage simulator.

A single triode stage circuit typical for guitar preamps is captured in this plugin. The model engine is based on a system of non-linear ODEs. Some smart calculation techniques are used to reduce the computational load.

This effect could be used to apply mild tube overdrive to add some presence to your tracks, or you could chain a couple of instances together for a full-blown high-gain overdrive. You may want to throw in some EQ as well to better shape the signal and use a poweramp/speaker simulator afterwards.

The plugin UI has a real-time transfer characteristic plot display. It provides an overview of the things going on inside the tube. It also has a peak-detecting algorithm that will flash a line when the level exceeds 0dB. You can monitor stereo channels separately or at once by clicking the corresponding buttons under the plot display.

16x switchable oversampling is also implemented to reduce the aliasing effects. Please note that for the most time the aliasing is low enough to switch off the oversampling. When oversampling is enabled, the plot display will not be of much use, because of the phase smearing introduced by the oversampling filters. Still good enough for monitoring the in/out levels.

The model has 3 core controls to configure the circuit:

3 different triode models: 12AX7, 12AU7, 12AT7.

3 different plate voltages: 150v, 250v, 350v.

3 different cathode capacitors: 0.47uF, 1uF, 22uF.

The gain/level controls are combined into a single knob that is operated with left and right mouse buttons.

The “Normalize Output” control enables the normalization of peak-to-peak output voltage swing across all triode configurations, particularly different plate voltages. By default it’s turned off to reflect the natural triode stage behavior, which could be regarded as a normalized small-signal gain.

Please note that output signal is not clipped at 0dB to let you overdrive chained stages using more that one plugin instance connected in series. Make sure to watch the output level or use a hard limiter somewhere in your signal chain.

Clicking on the SoftAmp logo in the plugin will bring up the “About” window with a version number and contact details.
