Cube Synth is a groundbreaking new software instrument giving you the power and flexibility of additive synthesis together with easy editing and morphing capabilities. Macro parameters allow you to control this beast with unequalled ease.

Intelligent 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 modeled after the inner workings of natural instruments.
Cube Synth 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…

Another entry in VirSyn's must-own lineup

I will readily confess that I own far more synth apps than I realistically need or use. But if I were tasked with actually picking a synth or two to actually create some music, Cube Synth (or any of the VirSyn synths) would be an excellent choice.

Cube Synth may actually be my least favorite of the (now) 4 VirSyn products, but it's still easily a 5-star product. The great thing about VirSyn apps is that they are friendly to the most obsessive sound designers ever, or somebody completely ignorant (or trying to learn) that wants huge libraries of varied sounds without having to make them from scratch. I'm probably more in the latter camp :)

The sounds in Cube Synth are rich and powerful. Aboslutely love the "dice" button which randomizes synthesis settings and creates a brand new preset on the spot (which you can save if you like it). How cool is that? The master effects suite is top-notch, and best of all the VirSyn apps take up virtually no storage space and work with everything. You'll regret some of your app purchases, but not this one.

First Impression - Nice!

Presets are much more organic than your standard subtractive. I find this one a bit cumbersome to program and it is difficult to develop patches that don't have that additive "buzzy" sound to them, but I'm giving five stars based on the fact that the envelope control is outstanding and totally innovative. Also, the arpeggiator, like the one in Addictive Synth, is especially nice.

Good concept, average sounds

I like Virsyn's Addictive Synth and AudioReverb, and bought this new synth right away. Theoretically, this should be a great instrument for evolving pads. In practice, though, I found the presets disappointing -- and there are a lot in the pad category. Maybe that's my fault for not taking the time to learn the instrument and program it to my liking. And if there were only five other synth apps in the app store, I would do that. But in my opinion, this is something to buy after you've already tried Sunrizer, Nave, Animoog, or Thor. You could argue that Cube is ahead of those other synths conceptually. (I'm not sure you would win, but you could argue it.) To my ears, though, the other synths sound smoother and, at the same time, more sinewy. I'm open to changing my mind, but for now I'm giving it four stars: good but not elite. They are fixing bugs, which is a good sign.
