Beatly Pro is a generative music studio for moments when you want to create but need a spark. Generate rap-inspired, lo-fi, chiptune, cinematic, and dance instrumentals, then shape them with hands-on arranging, editing, mixing, and export tools. Beatly Pro is not an AI music generator. It creates music on your device from curated patterns, musical rules, and controlled randomness. There are no prompts, cloud generation, or trained AI models. Style-aware melodies follow the harmony and develop across the arrangement. Varied instrument levels and effects give each track its own balance and character. FEATURES • Generate as many new musical ideas as you like • Create and arrange up to 8 bars across up to 7 mixer channels • Add a sampler channel and assign imported, recorded, or library samples to individual keys • Set each sampler key’s playback length and sequence it in the piano roll • Play chords on the sampler and piano-roll keyboards with multi-touch • Edit notes with pinch-to-zoom, playhead following, undo, velocity, copy and paste, per-beat transposition, keyboard lock, and custom patterns • Build chord progressions and change the key or chord of individual beats • Regenerate one instrument while keeping the rest of the track • Let Song Mode arrange generated bars for you • Set the key and tempo, or let Beatly choose them • Mix with volume, solo, mute, low-pass filtering, resonance, decimation, reverb, delay, and compression • Browse, search, and audition sounds in the Sample Manager • Record samples or import WAV and AIFF files, folders, and dragged files • Trim, fade, normalize, reverse, tune, warm, and drive samples • Import SF2 SoundFont banks, browse and audition their presets, and set note lengths • Save and recall reusable drum kits • Import a four-beat MIDI region into the piano roll, with optional transposition • Export a complete MIDI track or separate files for each instrument • Render a WAV mix, stems, or a seamless loop • Record a live performance to WAV • Share Beatly tracks with their custom samples included • Send MIDI with configurable channels and drum-note mappings • Connect through Audiobus with a full audio mix and separate MIDI outputs • Synchronize tempo and transport with Ableton Link WHO IS BEATLY PRO FOR? Beatly Pro is for producers, composers, singers, artists, filmmakers, game developers, content creators, practicing musicians, and anyone curious about generative music. HOW DOES IT WORK? Open Beatly Pro and tap Play. The app chooses instruments, tempo, key, and musical patterns, then creates up to 8 bars, or 32 beats, of instrumental music. Tap Next whenever you want a different idea. Rearrange or repeat bars, change the tempo or key, swap sounds, adjust the mix, regenerate one instrument, or edit notes in the piano roll. Add a sampler channel to build your own instrument from imported, recorded, or saved samples. Choose from five styles: Default, Lo-fi, Chiptune, Cinematic, and Dance. Default suits rap-inspired beats. Define the harmony with the chord progression builder, create reusable bar patterns, or change the key or chord of any beat. When your track is ready, save or share it, export MIDI, record a performance, or render a WAV mix, stems, or a seamless loop. Connect Beatly Pro to your studio through MIDI, Audiobus, or Ableton Link. CAN I USE MY OWN SOUNDS? Yes. Record audio, import WAV or AIFF files and folders, or load SF2 SoundFont banks. Preview, search, rename, duplicate, and edit samples inside the app. Replace an instrument’s sound or assign different samples to individual sampler keys. Samples tuned to C usually give the most predictable results when replacing a melodic instrument. Enjoying Beatly Pro? A rating or review on the App Store means a great deal. You can also support future development through the optional tip jar.
