What it is

XO is a drum sample organizer and instrument for macOS and Windows. It arranges samples by sonic similarity so users can audition sounds and rhythms rather than search folder by folder. The library includes more than 8,700 one-shot samples and more than 240 editable beat presets. XO sorts samples regardless of their storage location or format, including duplicates and files on external drives, and provides filters and search. For creating patterns, it includes Groove Templates, pattern nudging, and an Accentuator for adjusting feel and dynamics. Users can drag and drop samples, kits, stems, or complete beats as audio or MIDI, raw or processed. XO supports VST, VST3, AU, and AAX hosts, including Ableton Live, Logic Pro, Pro Tools, FL Studio, Reason, Reaper, and Cubase; a standalone app is also available. It supports MIDI, sample import, live performance tools, and eight pattern tracks. XLN Audio offers a 10-day full-feature trial without payment details. XO costs £76.20, paid once; XO + 4 expansions costs £95.40, paid once, and XO Complete costs £399.50, paid once.
