Visual Harmony vs G.ROUND

Immerse yourself in the stunning and hypnotic effects of Visual Harmony! In Visual Harmony, each note takes the form of a colorful shape rotating about the center of the screen. When the shape crosses the line, its note is played. Shapes closer to the center move faster than those farther out. These simple rules produce intricate visual patterns and hypnotic melodies. Watch as the shapes form spinning galaxies and winding spirals. See the patterns merge back into a line, only to unfold again into complex geometric shapes. Listen as melodies emerge from the motion. Choose a slow speed and settle into the gentle repetition, or speed things up for a lively swirl of sight and sound! Visual Harmony is an interactive musical/visual experience inspired by Jim Bumgardner’s invention of the digital Whitney Music Box. Explore the original at https://whitneymusicbox.org. At Excelltech Inc., we found Jim’s web app so engaging that we created our own version for iPhone and iPad. While staying true to the original idea, Visual Harmony gives you additional control and customization of the musical experience. Now rebuilt for today’s devices, it lets you reach into the patterns and make them your own. • Change the size, shape, speed, and color palette of the spinning notes. Reverse their direction, add light trails, and experiment with 4 to 88 notes. • Choose from six synthesized instruments: music box, piano, guitar, strings, brass, and organ. Adjust the volume and room ambience to suit your mood. • Explore pentatonic, major, minor, Dorian, whole-tone, and chromatic scales, or create your own sequence of notes and rests. • Move the line that plays the notes. Drag its handle across the shapes to sound them, even while playback is paused. • Explore the music forward or backward with the circular progress control. Grab its thumb and move your finger outward for finer control, or cross the top to move smoothly between the end and beginning. • Start with one of six included compositions, customize it, and save your favorites in your personal library. • Enjoy the visualization in portrait or landscape on iPhone and iPad. Open the floating controls to make changes as the music plays, then dismiss them to enjoy the view. If you are already a fan of the original music box, Visual Harmony gives you more ways to explore its patterns, sounds, and possibilities. If this is your first encounter, open Visual Harmony and let the music take shape! All sounds are generated on your device. No account, internet connection, microphone access, ads, subscriptions, or in-app purchases are needed. Requires iOS or iPadOS 26 or later.

G.ROUND is a generative performance instrument built for musicians who want to create grooves, chord progressions, basslines, and evolving synth textures from one expressive interface. At the center of G.ROUND are two harmonic wheels: choose a chord, shape its color, change its mode, and instantly turn musical ideas into playable progressions. Every engine follows the other: drums, bass, synth, arpeggiator, recorder, and MIDI output stay locked together while you perform. Build a beat with the drum sequencer, design each drum voice with layered synthesis and modulation, generate basslines that follow your harmony, then shape a four-voice synth with oscillator, filter, envelopes, glide, LFO, delay, reverb, and advanced voicing controls. G.ROUND is not just a sequencer. It is an instrument that reacts to harmony. Record a chord performance, edit it as musical information, then keep changing the sound around it. Swap drum patterns, reshape the bass, alter the synth, enable the arpeggiator, change presets, or send MIDI to external gear without losing the progression that started the idea. Features: • Dual-wheel harmonic performance interface • Chromatic and diatonic chord control • Chord extensions, harmonic colors, and “Nerd Mode” options • Four-voice polyphonic synth engine • Arpeggiator with multiple rates, swing, gate, octave range, chord patterns, and variation • Monophonic bass synth with root, pattern, walking, melodic, acid, riff, and blues-style behaviors • Drum sequencer with kick, snare, and hi-hat lanes • Two-layer drum voice design with oscillator/noise, envelopes, filter, tone, and level controls • Per-drum modulation synced to tempo or free-running in Hz • Harmonic performance recorder with bar-synced recording and playback • Detailed MIDI track editor for recorded chord progressions • Up to 99 complete session presets • Global mixer with synth, bass, drums, and master volume control • Delay and reverb for synth textures • Voice-leading, strumming, modulation, and pitch-bend performance controls • MIDI output via cable, Bluetooth MIDI, IDAM, and CoreMIDI destinations • Multiple visual themes and adjustable internal sample rate Whether you are sketching a new track, exploring harmony, designing electronic grooves, or controlling external instruments, G.ROUND gives you a fast, tactile way to turn one gesture into a complete musical system. Start with a chord. Let the machine move. Shape everything.
