Atlas 2 vs XO

Atlas 2 uses AI to sort and organize drum samples, helping users find sounds and build beats. It runs as a standalone application or as a VST, VST3, AU or AAX plugin in major DAWs, with downloads for macOS, Windows and Linux; Linux support is experimental. It accepts formats including WAV, AIFF, FLAC, OGG, MP3 and WMA. The drum sequencer imports MIDI while preserving its original timing, supports polyrhythms, and exports MIDI and audio loops. Users can map MIDI, send MIDI to other plugins or hardware, and drag drum pads into applications such as Ableton Drum Rack. Samples can be embedded in a DAW project with the Atlas plugin instance. The 14-day trial unlocks all features, then continues outputting audio but hides the interface and prevents editing. The full version costs 99.00 USD as a one-time purchase and can be installed on three machines; it is 64-bit only.

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.
