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”

StringView

Read full description

StringView is a visual fingerboard trainer for bowed and fretted string players. Choose your instrument, pick a scale, and explore the fingerboard as a clear, colorful map of notes, intervals, and scale degrees. 

Explore 16 scales and modes (more to come) StringView includes a complete set of essential scales and modes: • Major / Ionian • Dorian • Phrygian • Lydian • Mixolydian • Natural Minor / Aeolian • Locrian • Chromatic • Melodic Minor • Harmonic Minor • Pentatonic Major • Pentatonic Minor • Diminished (Whole-Half) • Diminished (Half-Whole) • Whole Tone • Augmented You can choose any root note and decide whether to display alterations as sharps or flats, so the view matches your musical background and preference. Notes, intervals, degrees, and shapes Display note names, intervals, or scale degrees on the fingerboard. Each scale degree has its own distinctive shape, and each note has its own consistent color to make patterns easier to recognize. Shapes and labels can be toggled independently, so you see exactly what you need. Harmonics and fret markers A dedicated harmonics mode highlights natural harmonic positions on the fingerboard. Fret markers, numbers, and octave zones offer multiple display modes so you can customize the view to your level and focus. Pinch to zoom Zoom in to focus on a few frets, or zoom out to see the full range — up to 36 frets across the entire fingerboard. Designed for practice Dark glass-themed interface with haptic feedback. Works on iPhone and iPad in portrait and landscape. Your instrument, scale, and display settings are saved automatically between sessions. This visual approach helps you internalize scales, understand the layout of your instrument, and discover new fingerings and melodic ideas — whether you already read music or prefer to learn by sight and pattern.
