BOSS releases RC-505mkII system program Ver.1.40
May 1, 2024 · 2 sources
BOSS released system program Ver.1.40 for the RC-505mkII in May 2024, according to the update history on the maker's support page1. The same page lists the previous release, Ver.1.30, as December 20231.
The update increases stability when Loop Sync mode is set to MEASURE and while using MIDI synchronization1. It also fixes an issue where the unit could freeze after recording a very short loop, an issue where effect banks might not switch correctly, and an issue where audio would be silenced when using the Lo-Fi effect1. BOSS further lists a fix for the STOP button blinking after going from the Tap Tempo screen to the Play screen with the EXIT button, and fixes for several issues that could cause a freeze and/or system error message1.
The RC-505mkII is a tabletop looper; the maker's page for looping pedals covers the category. The update is installed by holding the [EXIT] button and pushing the [POWER] switch, then connecting the unit to a Windows or Mac computer by USB cable and copying the extracted system program files to the RC-505MK2 drive1. BOSS warns that the data must never be applied to any product other than the RC-505mkII and that the unit must not be powered off during the update1.
"Increased stability when Loop Sync mode is MEASURE."
The same Ver.1.40 changes appear on BOSS's support page for the RC-600, dated May 2024, including the Loop Sync and MIDI stability improvements and the fix for freezing after a very short loop2.
