What's new in X!

- please reflash X! version if you have X installed - fully rewritten multiband compressor code. Proper studio grade algorithm - improved crossover bands - less noise on the input gain. Knobs also acts as a macro threshold. - added a redesigned MID/SIDE widener that uses dual parallel decorrelation paths to both turn mono material into stereo and enhance existing stereo content, with separate Mid and High implementations, including longer-delay filtering and subtle LFO movement in the High band for a livelier, more natural spatial image - fixed all possible buzzing VCA sounds as the ADC sample rate aligned with the audio rate

How to update the Endorphin.es Golden Master 1U

Update via audio. 1. Download the firmware update from the product page (zip, or the audio file directly) and use the newest WAV file. 2. Power off your modular system. 3. Unplug all cables from the module except one mono or stereo cable from your computer or phone headphone output to AUDIO IN 1. 4. Set the playback volume slightly below 100%, and turn off notifications and any EQ or audio effects on the player. 5. Hold MODE while powering the system on: the LED slowly blinks blue. 6. Play the WAV file (about 1 minute); the LED blinks blue quickly while updating. 7. The module reboots automatically when the update is installed. If the LED blinks red, stop playback, press MODE once to reset, adjust the volume and play the file again.

Just for reference. For complete and up-to-date instructions, always refer to the manufacturer's official firmware page.
