Empress Effects lists ZOIA firmware v5.32 as legacy download
December 15, 2025 · 1 sources
Empress Effects has listed ZOIA firmware version 5.32, dated 2025-12-15, on its Old Firmware Downloads page1. The same file, eezo0532.bin, appears under both the ZOIA and ZOIA Euroburo headings with the same release date1.
The page describes itself as holding legacy firmware for the Echosystem, Reverb, ZOIA and ZOIA Euroburo, and says the files are meant for users who need to go back to an earlier release1. The ZOIA list runs from v1.01, released 2019-04-26, up to v5.321. The entry directly before v5.32 is v5.30, released 2025-11-071.
The page carries a compatibility warning for early ZOIA firmware:
"ZOIA firmware version 1.05 and earlier is not compatible with newer ZOIA hardware. If your ZOIA has a serial number of approximately 2000 or higher, do not install firmware version 1.05 or earlier, as it is not compatible with your unit."
The page gives no release notes for v5.32 and does not say what changed from v5.301. Empress Effects also maintains a separate firmware updates page for current releases1.
