Pixelboop vs Shruti Bot

Make music as visual as it is audible. Pixelboop turns your iPhone or iPad into a visual sequencer where every note becomes a colored pixel on screen. No music theory required: tap, draw, and see the sounds. DRAW YOUR MUSIC Create beats by painting on a colorful grid. Each row is a note, each column is a moment in time. Tap to place notes, drag to draw melodies or chords, and watch your music come alive as patterns scroll across the screen. Music production that feels like a game. 4 TRACKS, INFINITE POSSIBILITIES Layer across four independent tracks: • Melody, expressive lead lines and hooks • Chords, rich harmonic backing • Bass, deep and driving low end • Rhythm, punchy drums and percussion Each track has its own color palette, so you can read a whole arrangement at a glance. 48 INSTRUMENT SOUNDS Sixteen sounds each for melody, chords and bass, from electric piano and glass pads to growling bass and bell leads. Hold a track's control column to audition and switch sounds while the loop keeps playing. EFFECTS YOU PLAY ON THE GRID Every track has its own effects column. Tap to switch between reverb and delay, compression and distortion, or a filter sweep, then slide to set the amount. No menus to dig through, and the column animates with what you hear. ALWAYS SOUNDS GOOD Pixelboop keeps you in key automatically. Choose major or minor and every note you place sounds musical. Note colors follow the circle of fifths, so harmonious notes look alike and clashing ones stand out. Interval modes let you explore different note relationships: • Pentatonic, classic 5-note scales that always work • Thirds, fourths and fifths, stack notes in musical intervals GESTURES THAT FEEL NATURAL • Tap an empty cell to place a note, tap the note again to erase it • Double-tap a note for an accent • Drag right to draw long, sustained notes • Move up and down as you drag across to build arpeggios • Hold a chord to cycle through the diatonic options ON IPAD The grid has no labels by design. On iPad, tap ? and it names itself: every control, every lane, and the note each row plays. Change key or scale and the names follow. It fades while you play and returns when you stop. EXPORT YOUR MUSIC (PIXELBOOP PRO) Bounce a finished jam to audio, export per-track stems to mix elsewhere, or send MIDI straight to your DAW. One purchase, no subscription, yours forever. SAVE, REPLAY AND SHARE JAMS Every session is saved as you play. Browse and reload any jam, set one as your starting template, or send it to a friend. Open a shared jam link and it loads straight into the grid. TEMPO AND TIMING Adjust BPM from ambient textures to driving dance beats. A visual playhead shows exactly where you are in the loop. Variable grid lengths plus 8 banks of 8 sections cover everything from a 4-bar loop to an extended arrangement. Loop one bank while you build it, or run the whole song. AUv3 PLUGIN Load Pixelboop inside AUM, Logic Pro or any Audio Unit host as a MIDI plugin. The same scale-locked grid becomes the brain of your studio, following your host's transport and tempo. MIDI AND HARDWARE Connect hardware synths and drum machines over USB or Bluetooth MIDI, with per-track send channels. Pixelboop also plays from an Erae Touch controller, with the grid mapped across its surface. DESIGNED FOR ACCESSIBILITY Pixelboop was created by a deaf musician who believes music should be visual first. The interface relies on color, position and visual feedback rather than requiring you to hear every nuance. Whether you are deaf, hard of hearing, or simply prefer a visual approach, Pixelboop meets you where you are. PERFECT FOR • Beginners who want to make music without learning theory • Producers looking for a fresh creative tool • Anyone who thinks visually and wants music to match • Educators teaching music through visual patterns • Deaf and hard of hearing musicians seeking accessible tools Music creation reimagined for the visual mind. Paint your first beat in seconds.

Shruti Bot is a shruti box you can actually tune. Ten reeds, laid out the way a real box is — the low Pa and Sa drone pair, the full middle saptak from Sa to Ni, and the upper Sa. Every reed sits at its just-intonation ratio against the tonic, not the tempered approximation, so the drone locks together the way the instrument is supposed to. Pull up the bellows and it breathes. At zero no air moves at all and the box is silent; push it up and the drone gets louder and pumps harder, until the breathing turns into an audible tremolo riding on top of the tone. Pressure opens the timbre as well as the volume, so a stroke sounds like air moving rather than a fader going up. THE REEDS • Ten stops — Pa and Sa below, Sa Re Ga Ma Pa Dha Ni across the middle, Sa above • Just intonation throughout — 3/2, 9/8, 5/4, 4/3, 5/3, 15/8 against the tonic • A tapered tuning peg on every reed, plus or minus 100 cents, turned by hand • Detune two neighbouring reeds and they beat against each other — real acoustic summing, not an effect • A mixer fader per reed, independent of the stops, for balancing what's already sounding THE KEY • Any tonic across all twelve pitch classes, octaves 1 through 6 • A peg for each key, arranged as a keyboard • Every pitch class keeps its own microtonal trim, so you can build a tuning that isn't twelve-tone equal temperament and it stays put • The current note and its offset are always on screen MOVEMENT • Two free-running LFOs on every reed — one for tuning, one for level • They run at their own rates and drift in and out of phase, so the beating keeps reorganising and the drone never quite repeats • Set them slow and the box simply sounds alive THE CHAMBER • A swept resonance that moves like a body cavity rather than a filter sweep • Stereo chorus, the point where the drone opens out of the centre • Tape delay with a real moving head — sliding the time bends the pitch the way tape does, and the repeats darken as they recirculate • Plate-style reverb from a quarter second to six TWO INSTRUMENTS Tap the logo. Shruti Bot 2 replaces the reeds with four analogue oscillators — sine, triangle, saw and pulse — with phase shaping on each, from slow comb sweeps to full PWM. Everything else carries straight over: the same tuning, the same reeds switched on, the same effects. Only the sound source changes. No accounts. No subscriptions. No ads. No network. Nothing leaves your device.
