--- MD Buddy - Ableton Setlist Controller MD Buddy puts your entire Ableton Live set in the palm of your hand. See every song, every section, and exactly where the playhead is - all in real time from your iPad. And now, your whole team can follow along too. Designed for worship teams, live performers, and anyone running Ableton backing tracks, MD Buddy lets the music director stay in control without touching the computer. Jump to any section on the beat, mute individual tracks per song, and keep the service moving without missing a note. REAL-TIME PLAYBACK TRACKING MD Buddy mirrors Ableton's playhead live - current song, current section, tempo, and bar number update as the music plays. A progress bar shows exactly where you are inside each section so you always know what's coming. JUMP TO ANY SECTION Tap any section button to cue Ableton to jump there. Jumps respect Ableton's Launch Quantization so they always land on the beat - no awkward cuts, no off-time transitions. OBSERVER MODE - YOUR WHOLE TEAM, IN SYNC Every other musician can now open MD Buddy on their own iPad or iPhone and follow the set live - current section, progress, tempo - without touching anything. No vocal cues, no guessing when the bridge repeats or the outro's coming. A green border shows at a glance which device is actually in control, and Settings lists everyone currently connected by name. TRACK MIXER Toggle individual Ableton tracks on or off directly from the iPad. Want to drop the drums for a quieter moment or bring in extra instrumentation? Tap once. Mute presets save automatically per song and restore every time you navigate back to that song. AUTOMATIC SETUP MD Buddy finds the bridge app on your Mac automatically - no IP address, no manual configuration. Connect via Wi-Fi or plug in a USB-C cable for a rock-solid stage connection independent of the venue's network. Save named Trusted Connections in Settings for an instant one-tap reconnect anywhere Bonjour discovery is blocked. SETLIST CONTROL Drag songs to reorder your setlist for the night. Your order is remembered between sessions. One device is always the primary controller; every other device connects read-only as an Observer, so accidental taps can never disrupt playback. FLEXIBLE MARKER NAMING Works with your existing Ableton project. Name songs using the == Song Name == convention or simply drop a marker called "Start" - MD Buddy recognizes common words in English, Spanish, French, German, Portuguese, and Italian. DEMO MODE No bridge? No problem.

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 eight 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 eight 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.
