Standalone FX AID editor application for PC or MAC :

windows 7 x64 > up

Mac OS 10.12 > up

Standalone application needs internet connection at first run to load program files and the current list of effects. After that the program will occasionally update itself and new effects automatically.

Entering firmware update mode: press and hold both buttons for 10 seconds. Two inner leds of the upper row will start to blink indicating the readiness for update. Play firmware file to the CV input to update the effects. In case some error occurs – two outer leds of the upper row will be blinking. Just press any button to reset this error indication and repeat playing of the firmware.

Line level signal amplitude is expected on the CV input for firmware update. So if you get error blinking, then try lowering the level.

Here is the factory bank preset, which can be loaded in the editor for easier editing.

Noise floor test: Sine wave generated by the FX AID under 100% wet, then its volume is decreased till silence and program is switched to empty slot, so only the noise floor is present.
