Billie Tracker vs Wavepocket

Billie Tracker is a groovebox: a step sequencer, synth instruments, a sampler and a mixer, built as one instrument for your phone or tablet. You write music in a grid. Notes go into patterns, patterns chain into sections, and sections line up into a song, so a full track grows out of small pieces you can reuse and rearrange. Trackers have worked this way for decades. If you have used one, this will feel like home. If you haven't, a built-in tutorial walks you through your first pattern, and every screen has help one key away. It is not tied to one sound. Shape the synths from clean tones to heavy drive, sample anything and play it back as an instrument, and make whatever you want to make: techno, ambient, hip hop, pop, or the 8-bit styles trackers are known for. Rows hold up to four notes, not just one. Every instrument is polyphonic, so a chord goes into the grid the same way a single note does. Hold one on a MIDI keyboard and it lands across the row's note lanes, quantized and in key. What you get: - A step sequencer for notes, instruments, volume and effects, with chains and a song view for arrangement - Up to four note lanes on every row, so chords are typed in like single notes, on any instrument - Synth instruments you can shape: timbre, color, filter, drive, envelopes and LFOs - A sampler that records straight into the app, so your own sounds sit next to the synths - A mixer with per-track levels and sends - BOUNCE and STEMS, so a finished song leaves the app as audio - Bundles: a song and every sample it uses travel as one file - A control surface built for tracker speed. Hold one key, press another, fast. Rearrange the layout to fit your hands, or plug in a hardware keyboard or game controller - Themes, KEY and SCALE settings, and a HELP key that explains whatever you are looking at Your songs are ordinary files. There is no account and nothing to sign into. Send a song to a friend, email one to yourself, or move it around in your file manager. Nothing is uploaded to us and nothing is locked to us. Billie Tracker is made by Billie Workers' Co-op. The people using it steer what gets built, and the Discord is the fastest way to reach us.

Wavepocket is a pocket studio: a synthesizer, drum kit, sampler and 4-track tape recorder that fit in your hand. Play it with your fingers: multi-touch chords, glissando slides across the keys, drum pads, and four color-coded encoders that always control what you're looking at. MAKE A SOUND: Analog (saw–square with sub), FM, and Cluster Engines • A sampler engine: play any recording chromatically across the keys • Slice samples on the waveform, name each slice, and flip between them • ADSR envelope, resonant filter, env→cutoff, LFO • Presets by category (bass, keys, strings, brass, lead, pad, pluck, bell). MAKE A BEAT: Synthesized 8-pad drum kit: kick, snare, hats, clap, tom, rim, bell • Kit-wide tune, decay, tone and level • Arpeggiator (up / down / up-down / random) and metronome MAKE A TRACK: 4-track tape with a clip timeline: record in any mode, then drag clips between lanes, trim their edges, and cut at the playhead • Everything shares one loop boundary, so your layers always line up • Mixer with per-track level, pan and mute • Filtered delay and spring-style reverb sends. KEEP EVERYTHING: Every tweak is versioned: undo, redo, or scrub the timeline of your session and annotate the versions worth keeping • Recordings and imports persist on your device between sessions • Save the whole project with settings, history, presets and audio as a single file, and render your mix to MP3 NO STRINGS: No account, no ads, no tracking • Works completely offline • Nothing leaves your device
