Tracker Pro: Sampler & Synths

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, or a full shortcut set on a hardware keyboard. Built-in instruments and effects, your AUv3 plug-ins, or both. Your own samples, imported or recorded.

Notes go into rows, three FX columns 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, patterns up to 128 rows, per-track lengths for polymeter
• 3 FX columns per step and 26 step commands, from retrigger, chance and glide to slice, macro, groove and jump
• Chords: up to 6 notes in a single step, on any instrument
• Tables: 16-row sequences that run inside a note, for arpeggios and rhythmic modulation
• Swing plus 16 groove templates, assignable per track
• 8 macros and 12 automation lanes per track, with knob-ride recording
• Song view with sections, repeats, loop ranges, per-track block mute and transpose, and live row cueing
• 100 levels of undo, copy and paste, ripple insert and delete
• Play and record from a MIDI keyboard or on-screen keys, 17 scales

SAMPLER
• Record from the mic, an audio interface, any track, a return bus or the master, or import WAV, AIFF and CAF
• Slice by transient, beat grid, equal 8/16/32/48 or by hand, up to 48 slices, and play slices from the grid
• Vintage character: true 12, 8, 6 and 4-bit resampling, plus Amiga-style Paula interpolation for the real 8-bit crunch
• Vintage stretch: S950-style cycle splicing keeps the pitch, varispeed does not. Fit any loop to bars
• 13 filter types, including E-mu-style morphing filters: peak/shelf, dual morph, vowel morph, dual EQ + LP and swept EQ, plus low-pass, high-pass, band-pass and notch
• 6-stage amp envelope, filter envelope and LFO, 4 modulation slots with 22 destinations, filter mod matrix
• Forward, backward and ping-pong loops with crossfade, gate and one-shot, choke groups
• Resample any track, or bounce it into a new instrument
• Sample editor: trim, crop, normalize, reverse, fades

SYNTHS
• MACRO: 24 synthesis engines built on the open-source Plaits code by Mutable Instruments: virtual analog, waveshaping, FM, wavetable, grain, harmonic, chord, speech, swarm, noise, strings, modal, analog drums, phase distortion, wave terrain, chiptune
• RESONATOR: modal, sympathetic string and modulated string physical models built on the open-source Rings code by Mutable Instruments, excited by the built-in exciter, a sample or another track
• Poly, mono and legato voice modes, with A/B compare while you tweak

EFFECTS
• 14 devices for track, return and master chains, any number per chain: Drive, Crush, Filter, EQ, Chorus, Phaser, Lofi, Delay, Reverb, Space, Resonator, Compressor, Limiter, Utility
• Tape on the master: saturation, dust, scratch and warp
• Two return buses, a protected master chain, 67 effect presets

AUv3 HOSTING
• Load AUv3 instruments and effects on any track or chain, each with its own interface in a resizable window
• Plug-in presets and state are saved inside the project

MIDI
• MIDI OUT instrument: notes, chords, bank and program change, and 16 control lanes (CC, pitch bend, pressure, sustain, NRPN) driven by macros and automation, with MIDI Learn
• MIDI in over USB, Bluetooth and virtual ports, with Bluetooth pairing built in

FINISH AND SHARE
• Export the master mix as 16-bit, 24-bit or 32-bit float WAV
• Self-contained projects with autosave and crash recovery, shared through Files or AirDrop
• 53 hardware-keyboard shortcuts and background audio

REQUIREMENTS
• iPad only, iPadOS 17 or later, landscape orientation
• Demo song, starter samples and presets included
• No account, no subscription, no ads, no data collection
