FAQ
What is REXS and what does it do?
REXS is a music production tool that converts your Logic EXS24 instrument libraries into the universal SoundFont (.sf2) format. This allows you to use your existing EXS24 instruments on your iPad, Mac, or any other SoundFont-compatible sampler.
How does REXS handle missing audio files?
REXS intelligently searches the instrument's folder, neighboring directories, and the entire file tree for missing audio samples. If a file is still not found, it prompts you to specify the correct folder to resolve the rest.
Can I combine multiple EXS24 instruments into one SoundFont file with REXS?
Yes, REXS allows you to build themed banks by combining instruments from various sources into a single .sf2 file. You can reorder, rename, and generate these combined banks for easy organization.
Does REXS modify my original EXS24 files?
No, REXS is designed to be non-destructive. It never modifies or deletes your original .exs files or their associated audio files. The conversion process creates new SoundFont files, leaving your originals untouched.
Is REXS available as a plugin for my DAW?
Yes, converted instruments from REXS can appear directly as an AUv3 plugin within compatible DAWs like AUM, GarageBand, Logic, and Cubasis, eliminating the need for manual exporting.
What devices does REXS support?
REXS is a universal app that works on Mac, iPhone, and iPad. Purchasing the app on one device allows you to install and use it on your other compatible Apple devices for free.
What is the pricing model for REXS?
REXS is a one-time purchase application. There are no subscriptions, in-app purchases, or different 'pro' tiers. You buy the entire app with a single payment of $2.99.
Does REXS collect my data or require an account?
No, REXS prioritizes user privacy. It operates 100% on your device with no cloud uploads, no account creation, no cookies, and no trackers. Your instrument libraries remain private and secure.
