• Save tone parameters as TON files: Compatible with the keyboard.

• Save and load tone parameters as JSON-formatted files: For CT-X700 and CT-X800 keyboards, which don't have user memory.

• Save tones directly to the synthesizer's internal memory.

• Rename tones stored in the synthesizer's memory: For better organization.

• Delete tones from the synthesizer's memory.

I am loving the app, but when we are on the main screen, and we select some tone, the Lock program. Another thing. I am a total blind, and the program is almost 100% affordable. However, on the list of tones, there does not seem to be a focus, sometimes making the screens reader not recognize the same. In the list of shades where we can erase, renamed could have some shortcut keys there, because with tab or shift tab, it is not possible to access these options. Perhaps if you add a context menu with the Applications key would be great.

Sorry for not replying earlier, I haven’t visited the forum in a while. Thank you for your feedback!
To be honest, I didn’t expect that my program would be used by people with visual impairments, so I didn’t anticipate potential accessibility issues. I’ll try to fix the focus behavior using hotkeys and release a new update!
But to be honest, at the moment I’ve lost interest in further development of the program. It feels like no one really needs it. The current functionality is enough for my own use, If I discover any bugs myself, I do fix them.
