Hacking Omnisphere 3: User MULTIsamples are a Thing!

TLDR: You can make your own multisamples for Omnisphere 3 — Spectrasonics never officially documented this, but the engine fully supports it. In this video, your old pal Keith reverse-engineers Omnisphere 3's user soundsource format (.zmap and .db files), maps multisamples by hand, and walks through real examples including Maurice White vocals from Earth, Wind & Fire, the legendary 10cc "I'm Not in Love" choir from Sampletekk's INIL library, drum kits, KRC Mathwaves Varieties of Noise sound effects, and more. Grab your XML parser and get ready for a multi-samples-a-go-go episode of your favorite talky synthesizer content show! (Already know how this works? The sequel covers round robins and sublayers — see the link below.) ─── WHAT YOU'LL LEARN ─── * What .zmap and .db files are inside an Omnisphere 3 user soundsource (and why no one has documented this) * How to drag-and-drop audio files into Omnisphere and convert them to multisample soundsources * How to edit multisample zones manually using a text editor (yes, really) * How to use Quadzone for pseudo-multisampling across the keyboard * How Omnisphere's granular engine and noise sources combine with user multisamples * What the mysterious HitKind parameter does (and what we still don't know about it) * How to convert .korgmultisample files to Omnisphere format using ConvertWithMoss ─── THE SEQUEL ─── 🎹 I Hacked Omnisphere 3 to Sound Like a ROMpler — covers round robins and sublayers, plus E-mu Proteus and Vulture Culture's Legendary Synths sample conversions: https://youtu.be/ygQ6Lp_MMy8 ─── TOOLS AND RESOURCES MENTIONED ─── 🎹 Omnisphere 3 User Audio import documentation: https://support.spectrasonics.net/manual/Omnisphere3 🛠️ Convert With Moss (mossgraber's multisample conversion software — turns .korgmultisample into SFZ, etc.): https://www.mossgrabers.de/Software/ConvertWithMoss/ConvertWithMoss.html 🎚️ Korg Sample Builder (map multisamples with a graphical interface): https://www.korg.com/us/support/download/software/0/928/4811/ 🎤 Sampletekk INIL Choir (the 10cc "I'm Not in Love" choir sample library): https://www.sampletekk.com/index.php?route=product/product&product_id=77 🎵 Digital Sound Factory (E-mu and Ensoniq sample libraries): https://digitalsoundfactory.com/ ─── ABOUT THE 10cc "I'M NOT IN LOVE" CHOIR ─── 📰 The Making of "I'm Not in Love" (Sound on Sound Classic Tracks article): https://www.soundonsound.com/techniques/classic-tracks-10cc-not-love 🎵 10cc — "I'm Not in Love" on YouTube: https://www.youtube.com/watch?v=rwsVgXG_zyI ─── RELATED VIDEOS FROM @kcrosley ─── 🎹 Omnisphere 3: Overview, Review, Synth Architecture, and History (the original 90-minute deep dive): https://youtu.be/VfbIxDRPwQE 📚 See all my Omnisphere videos: https://www.youtube.com/playlist?list=PLrpwUaHrI9tPHvEtD7ade8NzJWJ9zdkG6 ─── MORE FROM KEITH ─── 🌊 KRC Mathwaves (160,000+ wavetables, $29): https://www.wavetables.lol/l/wavetables/ 🌊 Free Wavetables Sampler (1,600+): https://www.wavetables.lol/l/free?layout=profile 🎹 Korg multi/poly Patches (90 performances, 105 programs): https://www.wavetables.lol/l/multipoly_patches_1 🎻 KRC Orchestral Impressions (38,000+ wavetables): https://www.wavetables.lol/l/orch?layout=profile 👻 Liminal Space reverb plugin (CLAP/VST3): https://www.wavetables.lol/l/liminal-space 🎁 33% OFF EVERYTHING — code THIRTYTHREE at www.wavetables.lol (limited uses) ─── ABOUT ─── Keith Crosley makes videos about synthesizers, wavetable synthesis, sound design, and music production.
