Negative Harmony vs Bionic Tape

Negative Harmony lets you explore one of music theory's most fascinating transformations: reflecting any chord or progression across a tonal axis to produce its harmonic mirror image. TAP ANY CHORD Select a root and quality on the interactive Circle of Fifths. See the original chord and its negative simultaneously, with voice-leading automatically applied. BUILD PROGRESSIONS Add chords to a progression and play them back — originals or negatives — with smooth voice leading between every chord. Common tones are held, not re-attacked. UNDERSTAND THE THEORY Built-in theory section explains the concept from first principles: the axis, the transformation formula, voice leading, and the history from Hugo Riemann to Jacob Collier. 5 SOUNDS Choose from Rhodes, Strings, Choir, Organ, or Synth Pad — the same high-quality soundfont used by professional music apps. MULTILINGUAL Full support for English, Spanish, French, German, Italian, and Portuguese.

Unfold, pick a tape, fold, listen. Bionic Tape turns your iPhone into a cassette deck. Unfolded, your playlists and albums sit on the shelf as cassettes, each in its case with cover art. Tap, and the tape slides into the deck. Fold the phone, and the tape rolls on the cover screen: reels spin, the tape hisses, the keys click. WHAT'S INSIDE • Fold instead of tap: the hinge decides whether you pick tapes or listen. Folding starts playback. • Keys you can press: real 3D keys with travel, click and haptics. PLAY latches while the tape is running. • Volume you can feel: a knob with an LED ring, a thumb wheel or a touch pad, depending on device and skin. 16 detents, each one clicks. • SHUFFLE: a slide switch plays your tapes in random order. • OUT: send the music to smart speakers, Bluetooth speakers or headphones. • Window: look through the window at the cassette with its handwritten label and the current song. The tape pack shows how much of the tape is left. • Tent mode: stand your iPhone up as a tent and the cassette becomes the show, with your playlist's cover art as the label. Tap to play/pause, swipe for the next track. • Full screen: tap the cassette and only the tape remains. • Seven skins: Translucent in see-through turquoise, 1983 in the style of 80s office computers, Sport in bold 80s yellow, Classic retro blue, Bionic OS, Cyberpunk and HMZ.swiss. • TAPE FX: hiss and clicks can be switched off. • Shelf: a tab per music source, RECENT for your latest tapes, search, and remove tapes you don't need. MUSIC • Apple Music: your playlists and albums as cassettes. Requires an Apple Music subscription. • Your own music: MP3, FLAC, AAC, ALAC, WAV and AIFF from the Files app, every album a cassette. Plays offline and in the background, with lock screen controls. • Plex: albums and playlists from your own Plex server, at home and on the go. • Demo tapes: work right away, no account needed. • Spotify: your playlists and albums as cassettes, played through the Spotify app (Premium required). You connect it with your own free Spotify developer app – Bionic Tape walks you through it. BUILT FOR THE IPHONE DUO Made for unfolding and folding. On iPhones without a hinge, a button switches between shelf and player. NO TRACKING No ads, no analytics, no account with us. Buy once, no subscription. A project from the HMZ workshop, Zurich.
