Oscillator Devices lists Trash Panda Quad firmware 1.4.0 as legacy update

December 23, 2025 · 1 sources

Oscillator Devices has listed Trash Panda Quad firmware version 1.4.0, dated 23rd December 2025, among the downloads on its legacy firmware updates page. The page is aimed at owners of devices bought before April 15, 2025, or of a Trash Panda Quad from the US warehouse purchased before September 15, 2025, who want to perform a firmware update.

The update is delivered as a MIDI SysEx file over a MIDI interface connected to a PC. The maker states that not all interfaces handle large SysEx files reliably, and warns that a failed transfer can leave the device erased. Interfaces the maker lists as tested and working include the RME Fireface, ESX MIDIMATE ex, SSL 12, MOTU Micro Lite and MOTU M4. Those listed as tested and not working for the legacy update are the Morningstar MC6 MkII (and probably all Morningstar controllers), the CME WIDI uHOST (and probably all CME WIDI devices) and PirateMIDI, which the maker says was not tested but does not support MIDI SysEx.

On Windows the maker cites MIDI SysEx file transfer utility as tested; on macOS it cites SysEX Librarian. The transfer takes approximately two minutes, and the maker says to ignore the progress bar and wait for a "Transfer Complete" message.

During the update the device reports its state through two LEDs. On the Trash Panda Quad these are Preset 1 and Preset 2, and the maker notes their logic is inverted: all are on at startup, and the ones that are off mean on. LED1 on with LED2 off means the device is ready to receive the update; LED1 on with LED2 blinking means the update is in progress; LED1 off means the update failed and should be tried again.

The page lists the Trash Panda Quad entry as version 1.4.0 dated 23rd December 2025, but the download file is named Trash-Panda-Quad-1.4.1.syx. The page does not explain the difference. The same table lists HYDRA4X 1.1.2 (3rd December 2025) and Siren-v2 2.1.1 (26th March 2025).
