Current Firmware

1.0.1
The 4ms Sampler uses an audio bootloader: download the .WAV firmware file from 4ms.info/firmware.php and play it into the module audio input at full volume while the module is in firmware update mode. The module has two hardware revisions (16HP pre-2025 and 12HP 2025+) that share the same firmware.

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