Explore the past

Humanity has travelled the world and all the seas. The sky is not the limit for us; we even reached the moon and beyond. But we were never able to explore the past (before). Only Retronaut, our LoFi Nostalgia Machine, may take you there. Fasten your seatbelts. The expedition through history starts now. 

Retronaut Key Features

LoFi Nostalgia Machine

Retronaut is a multi-voice vibrato and chorus with LoFi effects. It is inspired by old analogue gear such as bucket brigade chips, tape cassettes, vinyl records and voltage-controlled filters.

Vibrato to Chorus

The multi-voice engine allows you to mix from a single vibrato voice up to 4, resulting in a rich chorus. The mix is continuously variable, so you can find sweet spots between the voices.


Retronaut adds that nostalgic magic of the past, with multiple ways to age and degrade your music. Including warm dirt & grit, wow & flutter, dusty crinkles & crackles and more.


Offset the voices in various ways to create organic and evolving movements. Spread the voices over the stereo field, progressively delay them, warp their phase and even offset the LFO rate for each independently.

More Than Modulation

The heart of Retronaut is its modulation. However, you can dial back the "Vibe" and use its other effects. The tape saturation sounds so good it could have been a plugin on its own. Get that warm, woolly and compressed tape sound, then shape it with the VA filters and mix to perfection.

Crossfeed Into the Aether

The Feed control sends the signal from each voice back into each other to create a complex feedback network. Combine this with Lag to delay each voice and the filters for dampening to get a lush modulated reverb that sounds breathtakingly beautiful.

Virtual Analog Filters

The plugin has high-pass and low-pass resonant filters with switchable 2 or 4 poles to shape the tone of the effect. The filters can also be modulated with the LFO to add extra motion and flow to your sounds.

Hassle-free software protection

No iLok, no dongle, or internet access is required for activation. Our software uses license files to activate your software. You can freely use the purchased software on all your computers as long as you are the user.

Realistic 3D yet flexible GUI

The photorealistic graphic user interface of the plugin gives you the feeling you are touching the real hardware. But it easily adapts to your needs. You can always drag the arrow in the bottom right corner to change its size - make it smaller to save valuable screen space, or enlarge it to make it easier to use.

FREE 15-Day unlimited trial

All the descriptions are nothing compared to putting your hands on the plugin. No saving limits. No noises. No boundaries. Engage the plugin in your project for real and fully exploit its powers for two weeks.

64-bit audio quality at ANY sampling rate

The plugin provides the maximum audio quality you can get. It uses internal 64-bit audio processing and can handle any sampling rate. 192 kHz or even higher.

Smart bypass

The intelligent way our plugins manage bypassing ensures that you don't get any clicks or harmful noises when automating the parameter. It also compensates for latency, ensuring that the bypass states are perfectly in sync with each other.

Intelligent sleep on silence

This plugin intelligently detects whether it makes sense to perform processing at all. If not, it temporarily turns on sleep mode. In such a state, it requires virtually no CPU at all to save the computing sources for other processes.

Free-for-life updates

Our plugins never become obsolete. We keep track of the current operating systems and DAWs. You may always update to the most recent version for free, without paying a cent, a penny, or whatever currency you prefer.

Retronaut is possibly the best tape warp / lofi effects plugin I’ve ever used. Great for instrument buses when you want to create an interesting atmosphere & texture around the music.”

I hate to overdo the superlatives, but it has to be said that within a minute of trying out the amazing features of the Retronaut plugin, I am astounded. I particularly love the lo-fi Degrade section, which can add a huge amount of expression to any sound you use. Retronaut’s versatility will work across all manner of instruments, from guitars to drums etc. I even tried some of the effects on a piano piece, and the results were extraordinary.

Retronaut is a time and vibe machine. It's great for dialing in a little extra funk, grit, lo-fi, attitude or to save a sound from sounding too digital

Retronaut is not just another lo-fi maker. It’s so much more useful than anything else in its category. Because it’s not just a retro sound plug-in; it’s a retro enhancer.

It sounds absolutely amazing and it can create an instant retro vibe. It's literally one of the best retro plugins I have! Light on the CPU but doesn't compromise sound quality

Once again, JMG provides a unique processor with an extreme range of unique effects. If you work in any genre that can use unusual modulation FX, you should give it a try (free as always to try for two weeks and fairly priced). A load of fun!
