True analogue oscillators, filter, sample and hold, noise generator and VCA for authentic analogue sound.

1 x Logarithmic Voltage-Controlled Oscillator, with square, ramp, triangle and sine outputs, and PWM control of square wave. Square wave shape can be manually set to give pulse waveforms. The comprehensive range of frequency modulation sources includes 2 x LFO, Sample & Hold, ADSR contour, and external input. Switchable keyboard pitch range (normal, +1 octave and -1 octave), plus tuning control and pitch bend control.

1 x 24dB/octave, 4-pole Lowpass Filter, log response. Plenty of modulation inputs including ADSR sweep (for the typical filter automatic "wah" effect each time a note is played), LFO 2 (for repeat wah, bubbling effects, etc.), Sample & Hold, MIDI Velocity and external input. Re-create all those classic synth filter effects, or discover new ones of your own. Self-oscillation feature means that the filter can be used as an extra playable oscillator if required. Switchable keyboard tracking feature.

2 x Triangle and Square Wave Low Frequency Oscillators, with frequency and wave shape controls (much like those on the Korg MS-10 and MS-20), for vibrato and extreme modulation effects. Adjustable to give ramp, sawtooth, and pulse outputs in addition to the triangle and square waves.

1 x Built-in MIDI to CV Unit, with 5V gate and velocity output, 1V/octave CV response (can also drive external analogue gear). Fully variable glide (portamento) control, giving mild to extreme swoops of pitch when playing the keyboard, or when receiving external MIDI note information.

1 x Sample & Hold, giving crazy, random note effects and unpredictable filter modulation!

1 x White Noise Generator, can be used to add edge to imitative sound like flutes and whistles, or for rain, surf, thunder effects etc.

1 x ADSR Envelope Generator, drives VCA and VCF, with HIGH and LOW range switch. Bright yellow LED monitor and bypass switch for easy set-up. Useful ADSR repeat feature, driven by LFO 1.

1 x Linear Voltage-Controlled Amplifier with built-in germanium diode overdrive stage, for massive distortion effects - perfect for filthy solos and grungy basslines!

Electronic Music for Everyone

The Trax RetroWave desktop monosynth was designed for musicians who want the warmth and power of classic analogue synthesizer sound, created by a real analogue instrument, as opposed to a digital system. It is equally at home on stage, or in the amateur or professional studio.

Use it to recreate those classic synth sounds once made by Moogs, Korgs, VCS-3s, ARPs, etc., or make your own unique sound patches that are perfect for today's music.

Using the RetroWave is very intuitive - just turn knobs and flip switches to get the sounds you want. Unlike a digital keyboard, you are not stuck with a set of presets to limit your creativity!


Keyboard or Computer Control

Play soaring lead lines and powerful basslines in real time, or use your computer programs and a USB to MIDI converter cable, to achieve stunning, intricate sound patterns.

Connect any keyboard or sequencer with a 5-pin DIN MIDI out socket to the R-1's MIDI input socket, and you have an complete analogue synthesizer system for live gigs and recording - no MIDI setup to worry about, just plug in, select a channel and play!

You can also use it free-standing to create your own electronic sound effects for TV, video, DJ events, stage plays, etc., or to expand your existing analogue synth system.



The RetroWave's comprehensive "pot and switch" patching system lets you to set up sounds without recourse to endless menu screens. This way, you create electronic music from scratch - the way Carlos, Tomita, Jarre, Perrey and all the other pioneers did in the early days of sound synthesis.


Inputs and Outputs

The rear panel has inputs for 24V dc power supply, MIDI (via 5-pin DIN socket), gate, VCO CV (control voltage), VCO PWM (pulse width modulation), VCF CV, VCA CV and external audio (all 1/4" jack sockets). Output jacks are also provided for CV, gate +5V, velocity and audio.

The jack sockets can also be used in conjunction with the supplied patch lead, for extra interconnections between modules that are not catered for by the internal patching arrangement.


Power Supply and Accessories

The unit is supplied complete with a universal 24V dc power unit that will work on any mains supply from 100 to 240V ac,. There are three interchangeable plug tops - just attach the plug pin assembly that matches your local power supply socket.

A long 1/4" (6.35mm) mono jack to jack output lead is supplied, for connection to an external audio amplifier.

A short patch lead is also included, for making extra connections between internal sections as described above, or for connecting external effects units.


Case and Controls

The retro-styled steel case has a powder-coated, black and white paint finish. The construction is solid and robust, making the unit ideal for live performance use.

The controls and switches are laid out as ergonomically as possible, with plenty of space around the control knobs, making programming rapid and easy.

We deliberately avoided putting any sockets on the front panel, to keep the unit neat and uncluttered when in use - let's face it, nobody needs a tangle of patch leads getting in the way when trying to set up sounds!

All potentiometers are robust, full-size units, and all switches are good quality toggle type, as opposed to fragile and unreliable slide switches.

VCO (Voltage-Controlled Oscillator) 
Pulse width modulation and frequency modulation of VCO, via continuously variable controls

ADSR/VCA Section

ADSR envelope controls, for full control over Attack, Decay, Sustain and Release of sounds.

Rear Panel Sockets

View of rear panel - 1/4" jack sockets for signal and control inputs/outputs

Audio mixer and VCF (Voltage-Controlled Filter)

Comprehensive audio mixer feeds the VCF input.

Features an external high-level line input, for processing the outputs of other electronic instruments such as organs and pianos, or recorded content such as voices, music and sound effects.

VCF modulation from four internal sources, and an external source.

Low-Frequency Oscillators

Two Low-Frequency Oscillators, giving plenty of modulation possibilities
