RSF2 vs HeadStack

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.

HeadStack is a multi-head tape delay inspired by the character, movement and musicality of classic magnetic echo machines, reimagined for modern production. At its heart is a virtual tape loop with 8 independently configurable playback heads. Each head can be positioned, levelled and panned to create everything from vintage slap-back echoes and rhythmic repeats to vast stereo soundscapes and evolving ambient textures. While HeadStack captures the warmth and unpredictability of classic tape systems, it is not limited by their mechanical constraints. Individual heads can be modulated, filtered, diffused, pitch-shifted and transformed into granular playback engines, opening up a palette that ranges from authentic analogue echoes to shimmering harmonies and cinematic atmospheres. The tape itself becomes an instrument. Rotate the head wheel to continuously reposition playback points, stretch the spacing between heads, introduce head loss, or create cascading feedback networks that evolve with every repeat. Independent filtering, stereo placement and modulation allow each head to develop its own character within the delay line. You can even play sequences Into HeadStack and freeze it using your hold pedal and continue to play over the top. Whether you’re searching for vintage tape ambience, rhythmic multi-tap delays, lush granular harmonies or experimental feedback textures, HeadStack combines the soul of a classic tape echo with the flexibility of a modern creative effects processor. Welcome to a new generation of tape delay. HeadStack Features: Multi-Head Tape Engine - Create complex rhythmic delays using multiple independently controllable playback heads running on a shared virtual tape loop. Vintage Character - Capture the warmth, movement and musical imperfections of classic tape echo machines with adjustable tape loss, filtering and feedback behavior. Independent Head Control - Each playback head features its own level, pan, timing offset and tonal shaping, allowing intricate delay patterns and evolving stereo textures. Rotating Head Wheel- Continuously reposition or stretch the virtual head arrangement to create shifting rhythms, moving echoes and dynamic performance effects. Granular Harmony Engine - Transform individual heads into pitch-shifted granular voices, generating harmonies, octave layers and shimmering textures directly from the tape loop. Per-Head Modulation - Add movement and expression with independent modulation of playback position, spacing, tremolo and stereo placement. Creative Feedback Routing - Choose between traditional multi-head feedback or route feedback from a specific playback head for unique echo patterns and evolving repeats. Diffusion & Smearing - Blend between precise rhythmic echoes and spacious, atmospheric washes using integrated diffusion processing. Deep Stereo Imaging - Create anything from focused mono echoes to wide immersive soundscapes with per-head panning, Haas delay and stereo enhancement controls. Performance Ready - Designed for real-time interaction, encouraging hands-on manipulation of head positions, modulation and feedback while performing. Precision & Experimentation - Dial in authentic tape echoes, lush ambient delays or push the engine into unpredictable granular and feedback-driven territories. Modern Workflow - Combines the immediacy of classic hardware with the flexibility, recall and precision expected from a contemporary audio plugin. Interactive Head Wheel - Grab and rotate the virtual head wheel to reposition playback heads, create evolving delay patterns and perform dramatic tape-style scrubbing effects. Dynamic Tape Warping- Enable Rotate and Stretch modes to continuously morph the spacing and timing between playback heads, transforming static echoes into living, breathing rhythmic textures. Freeze Buffer - Freeze the contents of the audio buffer using a foot pedal, capture ideas and play over the top.
