=============================================================================================================

--------------------------------------------------------------------------------------------------------------
FW V1.21  (2025.4.1)
--------------------------------------------------------------------------------------------------------------
< Maintenance items >
- When the unit's GPIO setting was “Local”, the input audio would sometimes remain muted 
  even after the mute setting for the GPIO-IN analog input had been canceled from the Sonicview. This has been fixed.
- The unit could not be recognized by the Sonicview on rare occasions. This has been fixed. 
- Increasing the number of devices on the network would make it harder for the unit to be recognized by the Sonicview. This has been fixed.
- When the mute setting for the unit was canceled from the Sonicview, 
  the mute settings for other inputs and outputs could also be simultaneously canceled. This has been fixed.
- Operation stability has been improved.

--------------------------------------------------------------------------------------------------------------
FW V1.20  (2024.4.4)
--------------------------------------------------------------------------------------------------------------
< Maintenance items >
- When an SB-16D was mounted to the Sonicview, regardless of the settings, all SB-16D GPIO-OUTSs would turn to OPEN. This has been fixed.
- Dante settings were not initialized when Factory Reset was performed. This has been fixed.
- Operation stability has been improved.

--------------------------------------------------------------------------------------------------------------
FW V1.10  (2023.10.18)
--------------------------------------------------------------------------------------------------------------
< New functions >
- Connection from multiple IO CONTROL apps is now possible, with a maximum of 10 simultaneous log-ins, including TASCAM Sonicview 16/24.
- Pulse width and polarity settings for GPIO OUT are now supported. This has been applied in accordance with the additional functions in Sonicview FW (V1.5.0).

< Maintenance items >
- Operation stability has been improved.

--------------------------------------------------------------------------------------------------------------
FW V1.02  (2023.4.19)
--------------------------------------------------------------------------------------------------------------
< Maintenance items >
- If the GPIO-OUT port operation mode was set to “Extension” for multiple ports of this unit, a delay occurred in the output timing of each port.
  This has been changed so that output occurs with the same timing.
  Note: To enable these changes, update the firmware of the Sonicview unit to version 1.3.0. These changes will not take effect with version 1.2.0 or older.
- When recalling preset data from TASCAM IO CONTROL, the mute status before recalling would be retained. This has been fixed.
