Tracker Pro: Sampler & Synths
Vintage sampling, MIDI & AUv3
$14.99 · Designed for iPad. Not verified for macOS.
A tracker for samples, synths and Audio Units. Write patterns, shape each step and finish songs on iPhone, iPad or Mac. One purchase for all three.
Tracker Pro puts samples, synthesizers, Audio Unit plug-ins and MIDI gear in one pattern grid. Write drums, bass lines and chords, shape each step with commands, and arrange your patterns into a finished song.
Use touch controls, hardware-keyboard shortcuts or MIDI note input. On Mac, the same workspace also supports a keyboard and pointer. Built-in sounds and the STARTER 148 demo let you begin without extra equipment or downloads.
