Strings Dream strings machines VST/AU Plugin


The strings machines synth "Strings Dream" by NUSofting
has been fully rewritten: a complete sound engine upgrade, and x64 VST2 compatibility.

Currently a public beta release is free to download, for Windows X64.

download now: safe and free

[today 02 September 2019 I updated the SDS installer, therefore if you downloaded it before please dowload again and reinstall]

# This public beta has been released in the hope to receive feedback, to further improve its sound engine before the official release.

Write your suggestions at

# The Strings Dream public beta has a time limit of about 15 minutes per session, no other limitations, you can reload the plugin as many time you wish.

# The presets bank is not finished yet, presets from previous versions are included
but they need to be adjusted for the new SDS 2.0

SDS 2.0

What's new in SDS 2.0

# 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 articulationscompared 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).
 # MIDI CCs fixed mapping as:

New effects:
PHASER "Stages" selector:
1) "2=Notches" : a light phasing effect.
2) "4=Notches" : a typical swooshing effect.
3) "4+Damp"    : same as "4=Notches" but with dampened highs.
4) "2+Damp"    : same as "2=Notches" but with dampened highs.
5) "4+High Range" : swooshing effect shifted 2 octaves up.
The other PHASER controls are:
- LFO rate / speed
- Resonance / feedback.
- Width / range.
EFFECTS "Choice" selector:
1) "Delay Ambience" : a cross-talking stereo echo with vintage sound.
2) "Echo Ambience"  : coupling of "Delay Ambience" and "Algo Ambience"
3) "Algo Ambience"  : simple digital reverb
4) "Spring Reverb"  : a reverb emulating the colours of a "spring tank" electro-acoustic reverb.
5) "Vibra Chorus"   : a two voices chorus that converges to a mono vibrato
effect while the "Mix" knob reaches its maximum value.
can be used both as extra chorus or as vibrato for playing solos.
The other EFFECTS controls are
- Mix / Dry-Wet
- Size / Time.
- Bright / Amount.
- 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.
- 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)

*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, nothing fancy]

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

String Dream 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.  However, it has been extended for a wider range of "chorus" effects.

String Dream is easy to use.  It's 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.

We’ve provided a full ADSR envelope generator and Waveform selection (for several strings and organs sounds).

There is a volume fader and switch for each of 6 stops (C.Bass, Cello, Brass, Horn, Viola, 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.

Beside the chorus "Ensemble" effect, Strings Dream offers a four-stage Phaser for those famous "Jarre pads" and an exclusive reverb with the ability to morph on request to that "trembling" sound of the vintage spring reverb units.

Main Features:

- True analogue sound, VA "Octave Divider" emulation, (no samples used)
- 55 voices full polyphony, plus mono legato on bass section.
- Vintage audio effects on board.
- MIDI learn on every knob.


About Strings Machines.

A remarkable number of musicians recognize the desirable sonic character of “string machines”.  String machines were unique to the Seventies and nearly every major manufacturer offered some variation on the theme.  ARP’s biggest selling instrument was in fact their Omni, an instrument that combined a string machine with a simple synthesizer.  Even Moog got in on the act with their Opus 3.
 Just as the Rhodes™ piano and Hammond™ organs were intended as portable solutions to musicians who desired the sound of more cumbersome (and expensive) instruments, string machines were seen as the gigging musician’s alternative to the orchestra.  Or, at the very least, it was easier to carry around than a Mellotron!  Of course, the string machines didn’t sound like an orchestra, but had a character that today’s musicians find quite appealing on its own merits.

What makes a string machine?

This is a polyphonic electronic keyboard based on the top-octave divide-down technology as used in electronic organs to produce a fully polyphonic instrument from a single master oscillator.  This means that just a single oscillation is the primary cause of all frequencies of all notes played.  There are two main sonic characteristics of instruments that use divide-down technology: 

1) The waveforms are all derived from a simple pulse (on, off states) using post filters
2) The relative phase of the waveforms for all generated pitch is locked, more later about why this is so valuable.

Ensemble and/or Chorus effects were perhaps the main contributing factor to the sound of these instruments.  Not just any old chorus, either.  Only a good old-fashioned analogue BBD-based chorus or ensemble will do.  “BBD” is short for "bucket brigade device", a specific sort of analogue (not digital as we are used today) chip used to generate delay in audio:
