DrumComputer vs XO

DrumComputer is a synthetic drum instrument that combines synthesis, modulation, sequencing, randomizers, and sample import. Its eight sound engines each layer a resonator, a wavetable or analogue oscillator, and a resynth or sampler. The 16-step sequencer includes probability, rolls, step delay, swing, humanize, pattern generation, and remixing or fills. Effects include a filter, compressor, overdrive, and room and hall send reverbs. The desktop version supports MIDI file drag and drop plus multiple audio and MIDI outputs. It runs on macOS 10.13 or later and Windows 7 or later, with 64-bit versions for Intel and Apple Silicon. The iPad version requires iPadOS 17.6 or later and supports standalone and AUv3 operation, MIDI export, Ableton Link, MIDI Learn, host automation, and preset iCloud sync. DrumComputer costs $129, paid once as a download. A demo is available, but restrictions include a timeout after 30 minutes / 30 days and disabled saving and export. A Claude Desktop extension can create sounds from text prompts and requires the full version.

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.
