Mariana is a new software bass synthesizer from Moog Music capable of reaching the deepest depths of low-end tone and weight. Moog has long been a pioneer in electronic bass, from the iconic Minimoog Model D to the Taurus Bass Pedals, Sub Phatty, and Minitaur. Mariana continues this tradition in the form of a groundbreaking software synthesizer for iOS, MacOS, and Windows. Optimized for vibrant bass sounds that sit perfectly in the mix, Mariana is a powerful tool for artists and musicians across all genres and workflows. Mariana is a dual-layer synthesizer, allowing you to mix together two completely different synthesizer sounds and process each layer individually. Each layer is built around two oscillators with precise and inventive controls to dial in your bass tone to make it punch through a mix and stand out from the rest, with a sub-oscillator adding even more low-end weight. Two resonant Moog filters and a third filter specifically for the sub-oscillator let you shape your sound, adding warmth while rolling off high frequencies or pushing up the resonance for added bite. With stereo crossover functionality, Mariana is optimized for quickly dialing in stereo content while simultaneously preserving a strong mono bass foundation. Warm saturation and a tight compressor add extra punch to your bass lines while an illuminating real-time metering section lets you monitor your sounds and dial them in to a professional standard. Flexible built-in delay and chorus effects operate on separate layers and can expand the stereo image of your sounds or preserve a solid mono signal. Whether designing your own bass tones from scratch or using one of the 200 included presets as a starting point, Mariana is an accessible and versatile tool for any modern production environment. Mariana is fully equipped with three LFOs, three envelopes, and two random generators per layer and a creative and extremely deep modulation editor. Nearly every parameter of Mariana can be modulated internally, via MIDI, or via virtual CV from the Moogerfooger Effects Plug-ins, and Mariana's modulation sources can be sent to and received from the Moogerfoogers for a self-contained modular Moog ecosystem right in your DAW. With an optimized user interface and seamless integration into any DAW (digital audio workstation), Mariana is the most accessible way to add the unmistakable Moog bass sound to your productions. Features: • Modern Moog Bass: Mariana pulls from the lineage of classic Moog bass instruments to deliver a new bass synthesizer with cutting-edge features for sculpting powerful bass lines. • Dual Layers: Two separate synthesizer layers allow for complementary sound stacks or independent duophonic playing that can be mixed together. • Deep Modulation: A vast array of modulation sources, destinations, controllers, and functions with a deep mod matrix editor allow for complex modulation of nearly every parameter of Mariana. • Intuitive Interface: A beautiful, resizable, and user-friendly interface gives you effortless control over your bass sounds. • Metering and Compression: Built-in effects, compression, and metering let you add punch to your bass sounds and dial them in to a professional standard. • Interconnectivity: Mariana can interact with the Moogerfooger Effects Plug-ins via virtual CV, creating a modular Moog ecosystem right in your DAW. • Flexibility: Mariana can be used as a standalone app or a plug-in inside your favorite DAW, supporting powerful AUv3 compatibility. • Preset Library: A vast library of presets covering a wide range of musical styles and genres provides a starting point for users to dive right into musical creation - or transform stock presets into something completely unique. Supports: • AUv3 Audio Unit Extensions • MPE Controller Support • 7 and 14-Bit MIDI • MIDI Program Change Support • Share over Mail or other iOS applications ## Key features - Dual-layer synthesis - Deep modulation editor - Moog resonant filters - Sub-oscillator with dedicated filter - Stereo crossover functionality - Warm saturation and compressor - Built-in delay and chorus effects ## Pricing and in-app purchases Base price: $29.99. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Bass Booster #1 | $4.99 | one-time | | Bass Booster #3 | $4.99 | one-time | | Bass Booster #2 | $4.99 | one-time | ## Recent user reviews (10 of 35) All indexed reviews: https://appshunter.io/ios/app/mariana-bass-synthesizer/id6449554307/reviews.md ### 4/5 — Sounds *2026-03-03, version 1.2.0* Sounds good using Lfo nice sound ### 4/5 — Deep *2025-12-31, version 1.2.0* It sounds really good. But, hold on Moog, no presets for a Taurus emulation? Getting close is possible, but come on developers, you’re missing a huge trick there. This thing should be shaking the walls. ### 1/5 — Not sure if reported bugs will ever get fixed? *2025-12-03, version 1.2.0* Not long after using this app I started to discover bugs such as not able to save or load Midi Maps, constantly changing buffer size and not able to export presets. Communication with the developers is good but I am still waiting for these bugs to be fixed after 8 months and as a result I cannot to use this app until the ongoing bugs have been fixed. In stand-alone mode sometimes the notes stick when using the virtual keyboard rendering it unusable. 5th April. I hesitated for a long while trying to decide whether to buy this app or not, I took the plunge and bought it, but I never expected to be blown away by all its features and out of this world sounds, even the Darleks would hide if the heard some of these presets. My 13” iPad Air M2 handles it well in terms of CPU usage. My best purchase ever, can’t go wrong with Moog 👌 ### 5/5 — Like a digital Minitaur plus *2025-10-02* I love how phat and nasty this thing sounds. It does use some CPU, but I like to mix it with hardware synths, so I'm not trying to run several soft synths on my older iPad. I wish it was available on phone too, but lots of options and I can kind of grasp how to build patches. ### 5/5 — An amazing synth *2025-05-29* The sound is fantastic1 ### 5/5 — Powerful synth with great sounds! *2025-04-15* There's a lot to like about Mariana. First and foremost, the sound. The sounds and tone are great! ### 5/5 — WOW, BEST SYNTH ON iOS 👌 *2025-04-05, version 1.2.0* I hesitated for a long while trying to decide whether to buy this app or not, I took the plunge and bought it, but I never expected to be blown away by all its features and out of this world sounds, even the Darleks would hide if the heard some of these presets. My 13” iPad Air M2 handles it well in terms of CPU usage. My best purchase ever, can’t go wrong with Moog 👌 ### 4/5 — Immense sound with caveats *2024-12-29, version 1.2.0* This synth sounds amazing but will not run on an gen five iPad at anything above 32000Khz sample rates. You might have to keep resetting this which gets annoying fast. Worse still, if you try to run other synths or connect via inter app audio you might not be able to lower the sample rate as it will reset to 44.1 and will crackle and pop in an uneseable way. However, the sound is still awesome even at lower sample rates and blows the iMS-20 away for deep bass which surprised me as that synth is no lightweight. Worth the hassle and probably only an issue on older iPads. ### 5/5 — Review after 1 year *2024-12-02, version 1.2.0* + the best analog sound on iOS. - it uses too many resources . Being a 2 layered synth makes it worse cos there doesn’t seem a way to disable the 2nd synth (which I rarely use). - the modulation options are not so great. There’s no form of audio rate modulation: no FM, no ring mod, no AM, and the LFOs are so slow. A switch to make the LFOs fast would help. Still 5 stars cos the sound is pure analog pleasure. ### 5/5 — Bass and so much more… *2024-11-04* I’ve been iPad SY thing since 2013 with Animoog and have many hundreds of synth apps. A few stick out and stay prominently in use. This one is one of the newer ones so might still be a “honeymoon” effect, but fantastic presets and a fun, intuitive UI to tweak ‘em, this has been my first pick lately for drones and strange noises and of course, BASS. It’s difficult to pinpoint why, but Mariana just sounds so good and is so easy to manipulate that it just works in my mixes like few others. ## Frequently asked questions about Mariana Bass Synthesizer ### What is Mariana Bass Synthesizer?
