The Ensoniq ASR-10, re-imagined.
V4.2 talks to the real one.

ERX10 Edulator

The definitive ASR-10 editor & sample creator. 8-slot multitimbral emulator, advanced wave editing, advanced sampling (SPLIT & REX, chop with effects), synth-wave-to-instrument, AU & VST3 plugins for your DAW, your own plugins hosted on AUX2/AUX3, EFE-direct, CDR library, MIDI, live plugin sync — everything, in one bundle.

New in 4.2: send instruments to a real ASR-10 over MIDI and grab them back · a sequencer with songs, loops and controller lanes, saved as one file with its bank · MIDI file import · Kontakt NKI import · search inside every disk image · envelope REPEAT / FINISH modes · the new ERX One plugin.

ERX10 Plugins

Three plugins, one price: ERX Rack (8 slots, multi-out), ERX Rack Stereo (8 slots, one stereo out) and ERX One (one instrument per track, with per-track automation; Mac). Load ASR-10 instruments directly in your DAW — opens EFE files direct. Edit your sounds in the DAW, drag modulation sources to all their destinations, save ERX10 files — and, with the Edulator, send them back to the ASR-10 by MIDI SysEx or SD card. Logic, Ableton, FL Studio, Reaper, Cubase, GarageBand — any AU or VST3 host. Full envelope/filter/LFO, the built-in FX1 + FX2 effects, live sync with the Edulator. Plugin effects stay in your DAW, where you already have them.

Already own the plugins? Upgrade to the full Bundle — sign in and you're charged only the difference (never re-pay for plugins).

ERX10 Sample Library Control

Browse, tag, preview your entire EFE / EFA / ERX / WAV library. Import SD cards, create disk images, batch convert. v4.2: right-click menus to convert, reveal, and add any instrument in any image to the clipboard, create directories or categories, and paste it! Instant search inside every disk image, a new icon, Apple Silicon + Intel — plus automatic ZuluSCSI SD prep. Free forever.

ADEF Player

Plays ADEF patches in your DAW — the ones you build free in the browser, and the ones the Mac app makes. Logic, Ableton, Reaper, Cubase, FL, Bitwig, GarageBand. Inside: the UNIQUENCER per-step effect sequencer, arpeggios, host tempo sync, half and double time, editable unison, five stereo outs (Main + FX1–FX4) and a sidechain input. Every wave and texture is baked into the binary, so there is no library folder to install.

Build a patch free at the ADEF web generator, download it, and hit LOAD in the plugin. The Mac app above is where you build them by hand, arrange them and mix them.

The Windows ZIP includes 7 presets and 18 UNIQUENCER patterns, so it makes a sound without a second download.
