Fingerlab JYNTH is a new, authentic Roland Juno-106 Synthesizer emulation for iOS/macOS that is controllable with a physics engine.
In late May, the French company Fingerlab released JYNTH, a Juno-106 Synthesizer emulation for iOS and macOS featuring a physics modulation engine. In June, they added Aphex Twin-style features, giving you a sound per key and more.
Now the free update 3.0 is out with new additions. JYNTH 3.0 adds a new FX overdrive to the multi-FX section, and the repulsor object type to the physics engine.
It also adds a new live audio recorder and Bluetooth MIDI controller support.
The new JYNTH 3.0 update is available now as a free update for existing users. The app is a free update, and you can unlock the full version for $9,99. It supports both iOS and macOS (standalone and AUv3 plugin).

Update from June 18, 2026
At the end of May, developer Fingerlab announced JYNTH, a Juno emulation with physics modulation. It has been available since early June.
The free update 2.0 is now available, significantly upgrading the app once again and making it even wilder.
Fingerlab JYNTH 2.0
The JYNTH Synthesizer isn’t a typical Juno emulation, thanks to its physics modulators. The latter is an opening for experimental Juno sounds. It’s like putting your beloved Juno synth in a roller coaster car and riding it endlessly, but always on a different track.
JYNTH 2.0 takes things a step further and adds two more experimental features: Preset per note and preset ribbon, inspired by the music of Aphex Twin.
Preset per note lets you assign a different preset to each key on the piano keyboard, so every note you play triggers not only a different pitch but an entirely different sound. You can see it in the added picture.
Preset ribbon works similarly, but arranges a free-assignable number of presets in a row and lets you glide with your finger between them in real time. I played it briefly, and it’s a crazy feature that opens up a lot of creative possibilities.
Alongside these new features, it also comes with MIDI mappings and improves the app’s overall volume. It boosts the level for a louder, fuller sound right out of the box.
A great update for the JYNTH Synthesizer app, which came as a big surprise.
The new Fingerlab JYNTH 2.0 is now available as a free update for existing Full version users. As with the recent Fingerlab apps, New features mean a slightly higher price. The full version now costs $9,99/10,99€ up from $7,99/8,99€.
It supports both iOS and macOS (standalone and AUv3 plugin).

Article from May 28, 2026
The Roland Juno is a legendary Synthesizer series from the past. This is also one of the reasons why developers love to emulate these classics. On iOS, there are three available: AudioThing JULY, TAL-U-NO-LX, and the free app AudioKit Pro J6.
Do we need more Junos on iOS? I’d say no. Fingerlab, the developers of DM10 drum machine and Musyc2, says yes and is showcasing JYNTH.
Fingerlab JYNTH
JYNTH is a new analog modeling Synthesizer app and plugin for iOS and macOS, modeled after the legendary Roland Juno 106 from 1984.
At first glance, the Fingerlab JYNTH looks like a classic Juno emulation. However, at second glance, there is a major playing aspect that none of the previous ones have.
On the main page (SYNTH), you can find all the familiar controls of a virtual Roland Juno-106. Single VCO with square, saw, sub, noise, and pulse width modulation.
The mix goes into two recreated filters: one non-resonant high-pass filter and one resonant filter with frequency, resonance, and assignable modulation (envelope, LFO, and keyboard tracking).
Then, you have a single LFO with rate, delay, and depth controls, as well as a full ADSR envelope that is invertible on the filter. The VCA has a selectable gate mode, plus you have glide (portamento) control.
The built-in arpeggiator and the multi-FX section are located on a dedicated second UI page. Yes, that’s already a difference from the original. You can easily arpeggiate sounds with just a few controls: tempo, pattern, division, octave range, and gate.
A fairly basic arpeggiator. I would have liked to see more creative elements here, especially given Fingerlab’s reputation for playful features.
Playful Physics
Sound refinements can be done in the other sections of this page. There is a multi-FX section with five effects, including fully adjustable tremolo, flanger, chorus, delay, and reverb.
It looks like the Juno chorus has been done differently than in the original. We’ll have to see how it sounds.
A highlight of the new Fingerlab JYNTH is the physics engine. You can assign up to eight physics-driven modulators to any synth or FX parameter.
Parameters such as gravity, bounce, speed, impulse, and angle let you control the physics down to the last detail, and in ways you couldn’t achieve with an LFO. Alongside this, it supports MIDI and includes an audio background mode.
First Impression
I actually have enough Juno synthesizers, whether for macOS or iOS. I have to admit. However, the built-in physics engine makes it interesting by allowing you to explore Juno sounds in a new way.
You still have until June 4th to decide, because that’s when the app drops on the Apple App Store.
Fingerlab JYNTH will be available as a free download on June 4th, 2026. You can unlock the full version for $6,99/7,99€ as an in-app purchase. It runs as a standalone and AUv3 plugin on iOS (iPhone/iPad) and macOS (native Apple Silicon).

Hopefully Waldorf has started a trend. I’d love to see more vsts add this in.
