Get Inspired With Over 650 Presets & Incredible Sound Manipulation Tools!

“SynthMaster One” comes equipped with an easy to understand yet powerful interface, a massive amount of presets to draw inspiration from and also true Wavetable Synthesis abilities which open up new possibilities for sound design.

SynthMaster One Architecture

SynthMaster One’s architecture is intuitive and easy to negotiate, but boasts enough flexibility and depth to deliver a limitless range of electronic sounds.

It consists of two Oscillators with associated Sub Oscillators, the mixed outputs of which feed into two Filters, which in turn output to one or two envelope modulated amplifiers, followed by a series of master FX.

Routing Panel

The signal flow between the oscillators and filters can be reconfigured using the Filters menu here.

Browsing Presets

“SynthMaster One” comes with a huge library of over 650 presets that can be searched and filtered in the browser by:

  • Instrument Type
  • Attributes
  • Music Style
  • Preset Author
  • Bank Name

For example, if you want to see all trance-appropriate sequenced mono Factory presets by Aiyn Zahev, select the Factory Presets, Aiyn Zahev, Sequence, Monophonic and Trance entries in the five browser columns.

A Sound that’s Uniquely Yours – Voices, Oscillators & Filters!

“SynthMaster One” comes equipped with a whole bunch of ways to manipulate your sound… down to the finest detail. In fact it is such a powerful synth that it’s capabilities are far too many to list here! Here is just a taste of what to expect:

Voice Parameters

  • Polyphony Mode – Three voicing configurations are available, selected from the Mode menu at the top of the interface: Poly, Mono & Legato.
  • Glide – In “Mono” and “Legato” modes, the Glide knob (at the right hand side of the Keyboard panel) determines the time it takes to slide from one note’s pitch to the next.
  • Glide Type – The two Glide Types available here; “N”ormal and “S”lide, affect the way overlapping and consecutive notes are handled.


SynthMaster One’s two stereo oscillators are capable of loading standard analogue-style waveforms, as well as sampled single-cycle waveforms and wavetables.

Waveshaping Algorithms

The raw output of each oscillator can be shaped using one of 16 wave-shaping algorithms in four categories:

  • Spectral algorithms – Lowpass, Highpass, LowShelve, HighShelve, Bandpass, Bandstop
  • Bend algorithms – Bend+, Bend-, Bend +/-
  • Sync algorithms – Sync No Window, Sync Half Window, Sync Cos Window, Sync Triangle Window, Sync Saw Window
  • Other algorithms – Pulse1, Pulse2, Bit Crush

Importing Waveforms/Wavetable via drag-n-drop

Starting with version 1.0.5, you can drag and drop wave files/folders containing single cycle waveforms or wavetables onto an oscillator waveform display.


Filters in synthesizers are used to boost/cut certain frequency ranges, depending on their type. SynthMaster One has two zero delay feedback ‘analogue’ filters with four type categories:

  • Ladder Filter – Modeled on the famous Moog ladder filter, with a choice of two slopes (12dB/octave and 24dB/octave) and four filter types (Lowpass, Highpass, Bandpass and Bandstop).
  • Diode Ladder Filter – Modeled on the well-known analogue filter circuit of the Roland TB-303. Includes only one filter type: Lowpass with 24dB/octave slope.
  • State Variable Filter – Modeled on the analogue state variable filter found in the Oberheim SEM. This one’s available in four types: 12dB/octave Lowpass, 12dB/octave Highpass, Bandpass and Bandstop.
  • Bite Filter – Modeled on the 12dB/octave Lowpass.

Bring Your Sounds To Life With Modulation, Arpeggiation & FX!

As you would expect, “Synthmaster One” provides plenty of ways to add interesting space and movement to your music.

Modulation Sources

“SynthMaster One” features the following voice modulation sources, which are available separately for each voice (as opposed to global modulation sources – MIDI CCs, Constant, Keytrack, etc):

  • 4 ADSR envelopes
  • 2 LFOs
  • 1 Vibrato LFO
  • MIDI Velocity
  • Bipolar/Unipolar Random
  • Alternating


“SynthMaster One” features a very powerful Arpeggiator/Sequencer with up to 16 steps. Each step has it’s own Velocity, Length, Slide, Hold and Delta (Arpeggiate mode only) settings, and Note number(s) (Sequence mode only).

Using the Arpeggiator/Sequencer, you can create rhythmic arpeggios and polyphonic sequences. The Arpeggiator receives MIDI input and sends MIDI output.

The Arpeggiator/sequencer has the following modes:

  • Classic – Up,  Down, UpDown, DownUp, UpDown2, DownUp2, As Played, Chord
  • Arpeggiate
  • Sequence

FX Section

The signal flow through the FX section runs from the top of the ‘rack’ to the bottom. To load an effect into one of the six slots or replace a loaded effect with a different one, right-click the slot and choose a module from the menu.

  • Distortion – 2-band shelving EQ followed by a distortion stage, followed by another 2-band shelving EQ.
  • Lofi – applies bit depth and sample rate reduction (through sample and hold).
  • Ensemble – generates up to six ‘unison’ voices in parallel at different delay modulations.
  • Phaser – a 4-, 8-, 12- or 16-stage analogue modeled phaser.
  • Equalizer – a 6-band EQ, editable using the knobs and/or by dragging the filter nodes in the display.
  • Vocoder – consists of 16 analysis and 16 synthesis filters (1 LP + 14 BP + 1 HP).
  • Delay – a stereo delay effect with built-in 2-band EQ.
  • Chorus – the Chorus effect adds time variable delays to its stereo inputs.
  • Tremolo – modulates the amplitude of its stereo inputs based on the movement of an internal stereo LFO.
  • Reverb – a powerful Reverb effect, used to simulate rooms and spaces.
  • Compressor – used for dynamic gain reduction, automatically lowering the output level in response to changes in input signal gain.

So What Exactly Can I Do With “SynthMaster One”?

With it’s unparalleled flexibility, “SynthMaster One” opens up a whole new world of sound design possibilities for your next track, thanks to it’s huge collection of Oscillator, LFO and Modulation controls, as well as the fully featured Arpeggiatior/Sequencer and Effects rack.

The 650+ presets that “SynthMaster One” comes with mean you can get to work right away on your next track in whatever style you choose, including but not limited to:

  • Trance
  • Underscore
  • Chillout
  • Psytrance
