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”

Verdict

The call

The clearest difference is price: Tachyon at $1.99 against MIDI FX PRO's $9.99. Tachyon also leads on review sentiment (78% vs 50%) and ratings volume (13 vs 4). MIDI FX PRO's advantage is update cadence (monthly vs every 14 months) and rating (4.0 vs 3.8). On ads, in-app purchases, monetization model and device support there is nothing between them.
