Praise for our plugins
A little beast
BA-1 is our modern cult classic software synth, bringing you the authentic, gritty sound of analog hardware. Packed with sweet spots, easter eggs, and Baby Audio-quality effects, BA-1 is a synthesizer plugin that feels like a real instrument.
Modern tribute to a vintage classic
Our work on BA-1 started with a meticulous emulation of a quirky 1982 analog synthesizer. But as the project evolved, we took the liberty to make our own thing. We expanded the feature set and tweaked the sonic profile until we had realized our vision of a perfect re-imagined 1980s synth.
BA-1 combines the sound of nostalgia with modern convenience. No cables or batteries needed!
Sounds like hardware. Behaves like hardware.
We've brought you all the quirks that users of the real hardware loved (and sometimes hated).
Drain the battery, distort the signal through circuit-bending, use the built-in speaker as the output – or create unpredictable stepped glides with the Gliss feature.
BA-1 brings you a range of options to get an authentic lo-fi synth sound even before adding effects.
"Loving BA-1. It’s totally magical and inspiring!!! Sounds gorgeous and playful and really you can bring any kind of character out of it. The Re-gen button is genius, and the battery slider is so much fun. Just as slick and musical and fun as everything else you guys make. Brilliant work!"

"Another winner!!! BA-1 is such an inspiring retro synth. Just like their other releases, it’s a unique and refreshing take on throwback sonics combined with the coolest interfaces that make you excited to start tweaking. Baby Audio always packs so much creativity, fun, and flavor into every plug in that I use at least one on all my productions."

"Beautifully clean and punchy oscillators, super musical filter and the effects are super convenient. Gonna be a go-to from now on."

"In an age where you can get a plugin version of literally any synthesizer ever made, Baby Audio manages to create something unique that stands out, sounds great and is super fun to use. BA-1 doesn't sound like anything you've already got in your collection. This is a plugin I couldn't live without."
Michael Oakley
Producer and Musician
"I love the sound of this synth but also how incredibly simple it is. It's not cluttered with an overwhelming amount of features, which makes it actually super enjoyable to use. Definitely can see this being a go to synth for me."
Mick Schultz
Grammy-Nominated Producer - Jeremih, 50 Cent, YG, Gracie Abrams
"It’s only been about 10 minutes but yeah man – it’s AWESOME!! And you’re right – I don’t know of a lot of lo-fi synth plugins like this. Having just begun to mess with it, it’s already maybe the most interesting synth in my plugin collection."

"For a simple plugin, BA-1 is versatile. It hosts the vintage sound so well, all whilst being beautifully rounded!"
Jayce Lewis

"Once again, Baby Audio has managed to make something uniquely fun and useful even in such a crowded market. BA-1, like all of Baby’s tools, is immediately creative and inspiring – easy to use but with some deep capabilities – and above all, sounds fantastic and unique. Another go-to in my arsenal!"

Free effect plugin included
Effects to match the 80s aesthetic
BA-1's FX chain is not just onboard the synth but also included as a separate effect plugin with your purchase.
The FX strip captures the sound of budget 80s home studio gear and includes overdrive, filter, tone-shaper, delay, reverb, chorus and speaker effects.
Use it to add an authentic 80s flavor to any track in your mix.
Program new patches on repeat
BA-1 is simple to use, but surprisingly versatile. Program any synth sound from scratch with ease and discover new ideas along the way.
You can also delegate the programming to the smart Re-Gen feature, which automatically creates new, musically tuned patches with every click. Re-Gen is like a randomizer but just calibrated to deliver usable results every time.
Thousands of extra presets available
BA-1 already ships with 500+ factory presets. But if you want to explore cutting edge sounds for genres such as 90s electronica, chiptune and 70s disco, you can check out our growing collection of preset packs.

How BA-1 was developed
To create BA-1, we extensively measured the original analog hardware and recreated each of its main building blocks (oscillator, filter, envelopes etc.) with dedicated Virtual Analog algorithms that captured the instrument's character. Starting from this faithful emulation, the project evolved into a modern reinterpretation of the original hardware where the components were refined for a more musical and flexible response.
We intentionally built in imperfections from the analog domain to introduce non-linear behaviors. These include slight distortion from the output OP-AMP, speaker simulation (linear and non linear), experimental FM options and the battery mode, which emulates the hardware unit's battery power source.
For the effect section, we created an 80s style FDN-based reverb, an analog-inspired chorus, an early digital era delay, a musical gain compensated EQ and a side chain compressor to complete the signal chain.
The final result is not a static 1:1 replica of the original hardware that inspired BA-1 but a reimagined, modern-day version.
