When using a KATANA MkII amp connected via USB 2.0 to a WINDOWS or macOS computer and trying to connect with the BTS/BOSS TONE STUDIO for MKII software editor application, if your receive this message: "You are using an older version of Katana MKII. Update to the latest version," the user should update the firmware System Program on the KATANA MKII amp.
Note: Many new users confuse this message for a BTS or USB driver update, however it's for the amp's internal firmware System Program update and is the missing link for connectivity and amp firmware should be updated to KATANA MKII SYSTEM PROGRAM VERSION 1.10 if a new version exists please use the latest firmware update for your KATANA MKII instead.
Please click link below, download the firmware update zip and follow the PROCEDURE FOR THE UPDATE instructions.
*All KATANA 50/100/HEAD/212/ARTIST MKII amps all share the same firmware updates, drivers and downloads.
