Billie Tracker vs 2099 Techno

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.

2099 Techno writes complete tracks. Press generate and you get 76 bars with an intro, builds, two main sections, a breakdown and an outro, played by a virtual-analog engine and a 909-style drum machine. Bass, acid, stabs, pad, a lead line and the kit, through a dub delay, chorus and reverb. Nothing is sampled. Every note is made on the fly and no two tracks come out the same. The music comes from chaos maths. Three Lorenz attractors shape the melody, the rhythm and the mood. Three separate logistic maps run underneath the drums, the bass and the acid line, so they wander independently: turn the logistic control down and the hats and perc repeat every bar, turn it up and they never do. Chaos on its own is noise, so a small model filters it. It gets rewarded for consonant intervals and rehearses two hundred notes over the changes before it writes anything. The CHAOS / TASTE slider decides how much say each one gets. Eight styles, and they are properly different. Detroit rolls an off-beat bass under syncopated stabs. Dub Techno holds one chord for four bars and lets the delay do the work. Acid runs a 303 line with slides and accents. Hard pushes past 140 with a Reese bass and the drive up. Minimal takes most of it away. Every track is built from its seed. Write the seed down and you can have that exact track again, note for note, whenever you want it. You can play over it, too. The pads are the notes of the track's key rather than a piano keyboard, so nothing you touch is wrong, and the sixteen-step lane runs in time with the track and follows your host. Both play any part you like: bass, acid, stabs, pad or lead, through that part's sound and out on its MIDI channel. Choose which sections the lane plays in - just the breakdown, say - and preview it on its own without starting the track. Turn on RADIO and it keeps playing, picking a new key, mode, style, sound kit and tempo for each track. You also get: • 8 styles, 6 dark modes, 12 keys, tempo and density • Two-oscillator analog voice with sub, noise, resonant filter and glide • 22 presets and 9 sound kits, from Warehouse to Game Boy, plus random patch • Six-part mixer, dub delay, chorus, plate reverb and a global sweep filter • A PLAY panel: pads in the track's own key, and a 16-step lane with accent and slide, running in time with the track and only in the sections you pick • MIDI in, so your keyboard plays whichever part you have selected • MIDI export: six tracks, one per part • Live spectrum, waveform and a view of the chaos engine at work Two Audio Units, an instrument and a MIDI processor. Each part sends on its own MIDI channel, drums on 10, so one instance can drive six instruments. The MIDI version passes your keyboard through instead of swallowing it. Both follow your host's tempo and transport. One install registers both. The app is free and nothing in it is held back. Using the Audio Units inside other apps is a one-time purchase, and each AUv3 session plays for two minutes first so you can try them properly.
