Is your SoundFont library out of control? You've got dozens — maybe hundreds — of .sf2 files scattered across iCloud, old folders and forgotten thumb drives. Every time you need a decent acoustic piano, you waste 15 minutes opening file after file in your sampler. Each bank has 20 presets but you only use 2. Rsf2 fixes that — once. HOW IT WORKS • BUILD THEMED BANKS IN ONE TAP Pull presets from 5 different SoundFonts and generate ONE .sf2 file containing only the ones you love. "My 10 Favorite Acoustic Pianos" with Steinway, Yamaha, Bösendorfer and Fazioli — all in one file, ready to load in your sampler. • REORDER PRESETS BY DRAG Visual edit mode: drag presets to dictate the exact MIDI order (bank:program) in the final file. Want Steinway D at program 0:0? Bösendorfer 290 at 0:1? You pick the sequence. • SPLIT GIANT SF2 INTO PARTS Bought a SoundFont with 30 instruments but only use 5? Split it in a tap into individual files — exactly the ones you want. WHY Rsf2 IS DIFFERENT • 100% ON YOUR DEVICE No cloud upload. No account. No cookies. No trackers. Your SoundFonts (many of which you PAID for) never leave your iPhone, iPad or Mac. • UNIVERSAL A single app for iPhone, iPad AND Mac. Buy on any device, install on the others for free. • WORKS WITH YOUR SAMPLER Cubasis, AUM, GarageBand, Logic Pro, Audiobus, FluidSynth, ROMpler, MIDI hardware — anything that speaks SoundFont 2. WHO IT'S FOR • Live keyboard players using an iPad on stage • Producers wanting clean libraries in their DAW • Sound designers recombining banks • Church studios, music schools • Composers and arrangers • Beatmakers sampling from SF2 ABOUT THE FORMAT SoundFont 2 (.sf2) is an open standard created by E-mu/Creative in 1995, still very much alive in hardware ROMplers, free plugins and mobile samplers. Rsf2 respects 100% of the spec. GET STARTED Tap "Add .sf2 files", point at a file in your iCloud Drive, mark the presets you love, name it, generate. That's it. Make your library a place where you can actually FIND things.
