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…

Cool additive synth

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.

Truly Amazing

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.

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.
