Oscillator Devices lists HYDRA4X firmware 1.1.2 as legacy update

December 3, 2025 · 1 sources

Oscillator Devices has listed HYDRA4X firmware version 1.1.2, dated 3 December 2025, among the downloads on its legacy firmware updates page¹. The page covers updates for devices bought before April 15, 2025, or a Trash Panda Quad from the US warehouse purchased before September 15, 2025¹.

The update is delivered as a MIDI SysEx file, Hydra4X-1.1.2.syx, and requires a MIDI interface for a PC with a MIDI output¹. Oscillator Devices writes that not all interfaces handle large SysEx files reliably, and that a failed transfer can leave a device erased midway¹. The page lists the RME Fireface, ESX MIDIMATE ex, SSL 12, MOTU Micro Lite and MOTU M4 as tested and working, and the Morningstar MC6 MkII, CME WIDI uHOST and PirateMIDI as tested and not working for the legacy update¹.

On Windows, the page names MIDI SysEx file transfer utility as tested; on macOS it points to SysEX Librarian¹. Oscillator Devices says the transfer takes approximately 2 minutes and that the progress bar in the app should be ignored until a "Transfer Complete" message appears¹. During the update, the HYDRA4X reports status on its Master Red and Master Green LEDs: LED1 on with LED2 off means ready to receive, LED1 on with LED2 blinking means update in progress, and LED1 off means the update failed and should be retried¹. A device with a failed update may appear unresponsive but will still accept a new attempt, according to the page¹.

The same page lists Siren-v2 firmware 2.1.1, dated 26th March 2025, and Trash Panda Quad firmware 1.4.0, dated 23rd December 2025¹. The Trash Panda Quad download link on the page points to a file named Trash-Panda-Quad-1.4.1.syx, while the table gives the version as 1.4.0¹. No price or new hardware is involved; the HYDRA4X is a synth pedal, listed alongside others in our Synth Pedals section.
