XPN Builder is the pro expansion builder for Akai MPC.
BETA PROGRAM
Get early access with a free beta key. Test, give feedback, shape the product.
Drop 400 samples into a folder. XPN analyzes each sample's frequency spectrum — detecting kicks, snares, hats, and melodics by how they sound, not by filename. Auto-builds balanced kits in seconds.
Preview groove, pocket and swing inside XPN. Export the sequence with the pack so buyers load a kit and hear your demo immediately.
Trap · Drill · Boom Bap · House · Afrobeat · Lo-Fi · Reggaeton · Dancehall · Jersey · 4/4 · Electronic · Hip-Hop.
Export the same project as an Akai MPC expansion (firmware 2.x or 3.x), a Roland SP-404 MKII import, an Ableton Live Drum Rack, an NI Maschine pack, an Elektron RYTM pack, or a Universal WAV pack — six destinations from one source. Integrity check before every bounce.
A real sampler editor inside the builder: start/end, loop, tune, gain, fades, root note. No round-trips to a DAW for every fix.
16 kits × 128 pads × 4 banks in a single project. Switch in ⌘+[ ⌘+]. Batch-rename, batch-tune, batch-normalize across the whole pack.
Export ready-to-play packs for 6 platforms — same source, format-perfect output.
Full expansion with kits, sequences, previews and artwork — drag the .xpn into the MPC, browse it like a factory pack.
WAV 16-bit / 44.1 kHz organised bank by bank. Drop the folder onto your SD card, hit Import on the device — done.
Open the Drum Rack inside Live — every pad mapped, every sample loaded, patterns drop in as MIDI clips.
Pad-ordered folders so you can drag them into Groups in sequence. Tags file included for the NI Browser.
Samples auto-converted to RYTM specs. PadMap.txt lists which sample lands on which pad — drag through Elektron Transfer.
Kicks, snares, hats, melodics — sorted by the audio classifier. Works wherever WAVs work.
XPN Builder is the only tool in the market that treats your expansion pack like a studio session — because that's what it is. Built by an indie dev in Santiago who was tired of XML surgery and Expansion Builder crashes.
