Do you want to play an electric guitar and a piano at the same time? What about choosing the electrifying buzz of a drill and blending it into the soothing tone of a human voice? Jordan Rudess and Kevin Chartier’s Tachyon gives you all these options and more. From the makers of the award winning app, MorphWiz, comes a new creation that allows images and sound to become one as they magically blend under your fingertips. Each note you play is an individual expression, allowing independent control of pitch and tone far beyond that of traditional instruments. Most instruments only allow you to play one sound at a time, but with Tachyon, you can seamlessly blend between any two sounds as you slide your fingers up and down the screen. The visual experience of Tachyon is just as mesmerizing. As you move along the playing surface, a field of twinkling stars morphs into the shape of your selected instrument, allowing a direct correlation between sight and sound. As described by Jordan Rudess, “Tachyon is simple to use and at the same time offers a unique musical expressive power. The sonic core of the app is a custom crafted sound set from my personal library, encompassing sounds as familiar as those you would find in your home toolbox, and as exclusive as the ones I use on tour with Dream Theater." Whether you’re a seasoned musician looking for a next generation instrument to further express your creativity, or just a regular Joe browsing the app store looking for a fun and simple purchase that will delight the whole family, Tachyon is the app for you! “Check out Jordan Rudess’s new album with Steve Horelick entitled “interSonic”which features Wisdom Music Apps”

This compressor has the lowest total harmonic distortion of any plugin we have seen, including desktop units. At the heart of it is a unique envelope follower design that makes it possible to compress the signal without creating distortion harmonics. On the spectrum of compressor tone that ranges from "vintage analog" to "pristine digital", this plugin sits at the extreme end of low-noise digital clarity, but it is different from other low-noise digital designs because it doesn't use digital look-ahead. Therefore its response time is immediate, it adds no extra delay to the signal chain, and it works great for processing real-time performance effects. It uses no oversampling so there is no phase distortion or loss of high-frequency energy from anti-aliasing filters. It also uses no digital-style filters (FIR filters) and no digital look-ahead, so it adds no additional latency to the signal chain. Although it is not a model of an existing piece analog hardware, every component of its signal path is realizable in the analog domain. We think of it as a digital model of our ideal analog compressor: it could exist as an analog circuit but would be very expensive to build with physical analog electronic parts. The user interface is 100% scalable, designed specifically for iOS, so it looks beautiful at any screen size or orientation, from tiny portrait views in AUM on iPhone to the largest full-screen views on iPad Pro.
