Cube Synth Pro brings you the power and complexity of additive synthesis to your iPad studio. This kind of synthesis is well known for its potential capability of creating virtually any sound you can think of. But it’s also well renown for its huge amount of parameters you have to control for reasonable results. Therefore only a few synthesisers exists which uses this mighty synthesis technology. With Cube Synth Pro this prejudice will no longer be true. Specific sound morphing capabilities enables you to easily create complex evolving sound scapes, vocal phrases or stunning rhythms simply by choosing up to four sound sources from a predefined set. Then add one of the predefined envelopes and a unique, complex sound preset containing thousands of parameters is created! If you want to dive deeper into the inner secrets of this synthesis monster you can manipulate each parameter individually to get precise control over the sound. A number of high level parameters such as Brightness and Harmonic spread control hundreds of synthesis parameters in a way modelled after the inner workings of natural instruments. In addition to emulating natural instruments Cube Synth Pro gives you the ability to mimic the behaviour of the sound characteristic of vintage polyphonic synths by modelling the slight deviation from perfection which are inherent of analog systems. Cube Synth Pro gives you also a new method of getting randomly generated sound patches in a way you never experienced before: roll the dice! Every single try gives you a new unique sound patch, really every try, promised… Synthesis • Over 400 sound presets • Four morphing sound sources • Up to 512 partials per voice • Harmonic/Inharmonic spectra • User programmable noise spectra • Morphing filter banks • Unison mode with up to 8 oscillators per voice • Unique voice detuning scheme to simulate imperfections of poly analog synths. • 3 Envelopes with 64 time/level segments and tempo sync • Multi level random preset generator • 64 time/level segments per envelope Arpeggiator • Uses programmable sequences with up to 32 steps. • Can trigger single notes and chords. • Unique randomizer generates Arpeggios with 100% usability. • 32 Arpeggios included, unlimited useer arpeggios possible. • For each step you can program tie, accent, transposition and note order Effects • Chorus • Phaser • Overdrive • Ensemble • Echo/Delay • Reverb Global • Standalone App • AudioUnit AUv3 • Audiobus 3 compatible (Input slot) with state saving • Support for Ableton Link. • CoreMIDI / Virtual MIDI / Bluetooth MIDI • Audio recorder. ## Key features - Additive synthesis engine - Sound morphing capabilities - Over 400 sound presets - Programmable arpeggiator - Multiple built-in effects - Standalone and AUv3 support ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/cube-synth-pro/id1560948972/reviews.md ### 5/5 — Another fabulous virSyn Synth *2025-01-27* With a great metaphor for additive synthesis, highly graphical, and easy to interact with with many, many presets to learn and base your own as a tweak. Cube pro is not only. The good sounding sense but an inspiring one as well. It’s not as all encompassing as Tera Pro but it is an amazing set up. It is easy to play around with and find yourself with great sounding results. Although it can be warm, let’s be honest additive is a colder type of synthesis and Cube Pro embraces additive synthesis in a way that people familiar and unfamiliar will find enjoyable and useful. One of the things that I really like about the design is our results driven it is. Sometimes when you play with a new synthesizer, it can be daunting because of the interface. I’ve been involved as a tester, contributor, and friends to a couple of developers. Particularly I enjoy experiencing simple designs for complex instruments. I started with cube on the PC and actually enjoy the iPad version more because it’s so direct, deceptively simple, and fun to edit. Oh yeah, it sounds great too. Totally worth the purchase. ### 1/5 — Buggy *2022-02-05* I’d love to love this app, but annoyingly buggy. Some presets simply don’t load in the stand-alone app. When trying to use within Garageband, NONE of the presets are loading. ### 4/5 — Cool additive synth *2021-09-09* This is a nice update to the forgotten Cube synth. However, it has a bug where the pitch is affected by the sample rate. Please fix it. ### 5/5 — Amazing *2021-05-20* The variety of sounds this synth produces is phenomenal. ### 5/5 — Cubetastic *2021-05-18* More than happy to add this complex, yet workable and enjoyable synth to my colourful palette 🎨 of sounds 🎶. It's above and beyond most others in my collection. Haven't stopped playing with it since I bought it the day after its release 😎 ### 5/5 — WOW! *2021-05-17* You guys are masters of sound. It’s incredibly impressive what you are able to program in this iOS space. I’m blown away. Every patch is a goldmine and opens up new dimensions of sonic possibilities. Thanks for your constant creativity and pushing the boundaries of what is possible in software synthesizers. Jordan Rudess Wisdom Music/Dream Theater ### 5/5 — My dream has come alive! Best iOS developer hands down! *2021-05-17* A massive Visyn fan before they even graced the iOS scene. ****IS IT POSSIBLE FOR CANTOR WILL BE NEXT? Either way, between this app and Addstation being the finest Additive Synthesis app on iOS the bars too high for anyone to keep up. ### 5/5 — Truly Amazing *2021-05-16* Virsyn has all but cornered the market of additive synthesis. CubeSynth Pro taps into the methodologies implemented in previous releases, like AddStation, and added a wave sequencer. The app includes Virsyn’s excellent effects system, and a compelling modulation matrix. This is probably not for people who don’t have time to read manuals, or watch tutorials. The presets are fantastic, especially to learn about how to design sounds. ### 5/5 — Another Great Virsyn Masterpiece *2021-05-15* Again, I just buy Virsyn app the instant i see it because they are always great. Never disappointed. Thanks Virsyn ### 1/5 — Wasted money! *2021-05-14* Stand alone doesn’t have note hold. AU completely designed differently (I can’t stand that!). Everything is TOO HARD TO READ in the AU! Deleted and that’s it on this developer! No more. I have aboutsix of their apps I’m also deleting. I just don’t use their stuff. They’re too unresponsive. **Developer response:** Sorry for having you upset. You find the Key hold function in the Keyboard settings ( Tap on Gear icon above keyboard ). Version 1.1 improves AU interface readability ## Frequently asked questions about Cube Synth Pro ### What is Cube Synth Pro?
