DreamStation DXi2
DreamStation DXi2 is a free software synthesizer developed by Audio Simulation. Available format(s): DirectX for Windows.
DreamStation DXi2 is a polyphonic analog synthesizer plugin based on DreamStation I.
DreamStation DXi2 utilizes the same techniques featured in the standalone version; physical models of analog circuits, mathematical reproduction of analog oscillators which makes DreamStation DXi2 acting just like real analog synthesizers. You can sweep the pitch smoothly from 20Hz to 20kHz and apply the pulse width modulation without any digital aliasing at all.

- Subtractive synthesis combined with FM synthesis.
- 3 oscillators, multimode self oscillating IIR filter, VCA, LFO, user EG for each voice.
- Available waveforms: sine, triangle, sawtooth, pulse, square, noise.
- Available filter types: 12dB/Octave Lowpass, Highpass, Bandpass, 24dB/Octave Lowpass and Formant.
- A maximum of 16 voices polyphony.
- Linear frequency modulation, Hard synchronization, Ring modulation, Distortion.
- Supported sampling rates: 11.025Khz, 22.05Khz, 44.1Khz, 48Khz and 96Khz.
- Supported digital audio resolution: 16 to 32bits.
- Internal calculating resolution: 32 bits (with 24bit mantissa).

Dream Sequencer
Dream Sequencer is a free software synthesizer developed by Dream Vortex Studio. Available format(s): VST for Windows.
Dream Sequencer is for that sequencing sound of the 70’s as produced by Tangerine Dream, etc. The VSTi synchronizes with the host BPM and takes its root key from a “MIDI note” and plays for the duration from “note on” until “note off”. The pitch knobs are quantized to semitones with a range of one octave.

Dominator
Dominator is a free software synthesizer developed by Computer Music. Available format(s): VST for Windows 64b.
Programmed from the ground up to CM’s own specifications, Dominator takes the venerable sound of classic analogue synths and beefs it up with modern routing, modulation and waveshaping options.
Features:
Triple Oscillators
- Three oscillators per voice with a choice of six waveforms (Saw, Pulse, Sine, Triangle, Sync Saw, Sync Pulse).
- Pulse width modulation per voice and coarse (4 octave range) and fine tuning adjustments.
Oscillator Control
- Dedicated LFO to control vibrato depth and pulse width modulation.
- Glide time setting and mod wheel vibrato depth control.
- Analog control for adding fat analogue-style detuning.
Voice Control
- Four voice modes (monophonic, polyphonic, unison and chord mode).
- Unison with 2, 6 or 12 voices.
- Chord mode with 5 user-definable intervals (plus root note) for building up complex chords to be triggered from a single key.
- 6 play modes for mono/unison/chord, for controlling when glide should be applied and when envelopes should be reset.
- Smart mode for handling successive presses of the same key, or Reset mode, where all envelopes and oscillators are reset for each note, for a punchier sound.
Mixer
- Independent levels for each oscillator.
- Noise and ring modulation (between oscillators B and C) can also be mixed in.
- An external input signal can be mixed in on the VST effect version (this is mixed into each voice).
Amplitude Envelope
- Classic ADSR envelope with velocity sensitivity.
- Optional ‘Warm’ VCA mode gives a non-linear analogue-style response.
FX
- Chorus modeled on the classic Roland Juno chorus, with depth and rate controls.
Dual Filters
- Two fat multimode Moog-style filters per voice, with 5 filter types (lowpass 12/24dB, bandpass 12/24dB and highpass 12dB).
- Filters can be overdriven and can be made to self-oscillate, just like true analogue filters.
- Keytrack, velocity and filter envelope can all be used to modulate the cutoff frequency.
- Optional ‘Warm’ mode drives filter harder to add more oomph and body.
Filter Envelope
- The classic ADSR envelope for modulating cutoff of the filters.
Waveshaping
- Optional waveshaper per voice with five different modes and drive control (goes up to 11).
- Transistor, diode, hard clip, sine and rectifier shaping modes.
Routing
- Waveshaper and the two filters can be configured in five different arrangements, including serial and parallel configurations, for flexibility.
LFO
- LFO with sine, triangle, square, positive-only square, sample and hold and noise shapes.
- Can modulate amplitude, oscillator pitch B, oscillator pitch C, filter A and filter B.
Modulation Envelope
- ADSR envelope to modulate filter B, pulse width modulation, vibrato depth, oscillator pitch B, oscillator pitch C and noise level.

Dolphin Bassline
Dolphin Bassline is a free software synthesizer developed by Signaldust. Available format(s): VST for Windows.
Dolphin Bassline is a simple monosynth with a diode-ladder filter circuit-model and the general feature-set inspired by the famous silverbox. It’s not an entirely serious reproduction, but still attempts to match the general character to a certain degree.

Distel
Distel is a free software synthesizer developed by TOK-TOK. Available format(s): VST for Windows.
Distel was more or less the Test synth for Fratzoor, but in the end it didn’t sound too bad I think. There is not a lot to say about Distel. It’s based on subtractive synthesis and distorting in many different ways (1 Waveshaper for each Oscillator and another Waveshaper behind the Filters) has a bass enhancer with several controls and some other things you will find out.
There are some hidden features 😉
Use the volume controls to manage distortion a bit.
You use Distel on your own risk.
- 2 Oscillators, 1 Waveshaper for each.
- 3 different Filters + adjustable modulation-amount.
- (Signal Flow : Filter 1,Filter 2, Filter 3) + another Waveshaper.
- 6 Voices and different Voice-Modes.
- adjustable Bass-Enhancer (fixed frequency at 80Hz).
- LFO+Filter and Amp Envelope.
- Windows 32-bit (works bridged as 64-bit).
