The tracker rethought for touch now keeps a whole kit in one sampler, turns any sound into grains and lets it bloom, with up to eight commands on every step.
Tracker Pro is the music tracker rethought for touch: a sampler with vintage soul, 24 synth engines, your AUv3 plug-ins and MIDI gear in one grid, from first idea to finished track.
Work your way: fingers on a grid built for touch, shortcuts on a hardware keyboard, or a MIDI keyboard. Notes go into rows, up to eight commands shape every step, and patterns become songs. Tracker veterans will feel at home in a minute; everyone else gets a fast, precise way to write beats.
TRACKER
• Up to 16 tracks and patterns up to 128 rows, with independent track lengths for polymeter
• Up to 8 FX slots per step and 26 step commands, from retrigger, chance and glide to sample start, slice, groove and jump
• Chords of up to 6 notes on any instrument, note tables, swing and grooves
• 8 macros and 12 automation lanes per track
• Song view with sections, repeats and live row cueing
SAMPLER WITH VINTAGE SOUL
• Keep a whole kit in one Sampler: add files or a folder and choose the sample for each note
• Let a note pick a random sample, a random slice or both, so a pattern changes as it plays
• Slice by transient, beat grid or hand, up to 48 slices, and play the slices from the grid or pads
• Modern, Amiga, M3000 and SP12 playback modes, or set bit depth, sample rate and interpolation yourself; lower bit depths really resample the audio
• Stretch loops to fit bars, play forward or reverse, and build crossfaded loops
• Morphing filters with a six-stage filter envelope, plus amp envelope, LFO and modulation
• Record from the microphone, an audio interface, any track, a return bus or the master, and resample tracks through their devices
• Import audio from Files, or extract it from a video in Files or Photos
SYNTHS
• Macro: 24 synthesis engines for basses, chords, percussion and evolving tones
• Resonator: modal and string physical models, excited by its own exciter, a sample or another track
• GrainOSC: pitched grain textures from 12 built-in wavetable banks
EFFECTS
• 15 built-in effects for track, return and master chains, including Granular FX, Ambient Reverb, Space, Delay, Drive, Lofi and Compressor
• Granular FX scatters, reverses and freezes grains of incoming audio; put it after a Sampler to process your own recordings
• Ambient Reverb adds Cloud and Bloom modes, long decays, Sustain and Hold
• Two return buses and a master chain
YOUR PLUG-INS AND GEAR
• Host AUv3 instruments and effects on any track, each with its own plug-in interface; presets and plug-in state save with the project
• MIDI Out with notes, chords, bank and program changes, and 16 control lanes
• MIDI in over USB, Bluetooth and virtual ports
FINISH AND SHARE
• Export WAV mixes and individual track stems
• Self-contained projects with autosave and crash recovery, shared through Files or AirDrop
GOOD TO KNOW
• Designed for iPad in landscape, iPadOS 17 or later
• Demo song, starter samples and presets included
• Pay once: no account, no subscription, no ads
