It will be perfect !!! Fine app to complete with J6 or Super J8 ### 2/5 — Pas de canal MIDI en AUV3 *2026-06-06* Pouvoir utiliser l’app comme extension AuV3 est super utile, mais ne pas pouvoir changer le canal MIDI comme dans la version standalone est totalement bloquant pour l’utiliser dans un sequenceur moderne comme Koala par exemple (la reception MIDI par defaut est ‘omni’, la forcer sur le Canal MIDI 10 - communément utilisé pour les drumbox - serait un minimum). ### 1/5 — DO NOT BUY UNTIL UPDATED *2026-05-11, version 1.4.2* You will know when to buy again based on the most recent time it’s been updated Until this (it is currently May 11th 2026) do not purchase It’s a good plugin for the most part other than that ### 5/5 — still love, it still great,STILL DATA NOT COLLECTED *2025-10-30, version 1.4.2* dunno why it hasn't been updated in three years,maybe because it still works FANTASTIC 😍 ### 1/5 — DOESNT EXPORT MIDI *2025-10-26, version 1.4.2* Was extremely disappointed to find you have no way of actually exporting these drums in to a place like Logic. Fun to mess around with but not practical for getting the drum loops anywhere useful but your phone ### 5/5 — Love it *2025-09-22* For this Price, the best what you can buy. A really fantastic drum Maschine with AuV3 Integration. ### 5/5 — хороша драм машинка *2025-09-19, version 1.4.2* з недоліків - наразі не завантажує пресет. потрібно перевибрати при запуску. в решті все добре. ### 5/5 — Awesome app *2025-05-24, version 1.4.2* U ### 1/5 — WONT RECORD IN CUBASIS 3 *2025-05-22, version 1.4.2* Running this in Cubasis 3 as a audio app it runs, but is not recording ... i was convinced it did a short while ago Im going to remove and redownload just incase and see what happens . ## Frequently asked questions about LE04 | AR ### What does the LE04 | AR-909 Drum Machine app do?
