MIDI Target Manufacturer(s): Other/Unlisted Maker
In MDPx for Mac OS and iOS, applying a Sysex Property MIDI value change may/will fail. Case in point, when activated with red dot, there is no way to make a MIDI value change since Apply Now never appears. When activated with green dot, the Apply Now only appears at the bottom right, but not at the top left. Thinking clicking the return arrow to close the window will apply any change, it does NOT in either mode. I have occasionally changed the Sysex value and hit the return arrow as I normally would, only to have my change fail and having to go into a troubleshooting mode.
If I remember to select the green dot mode and Apply Now at the bottom right, the Apply Now appears at the top left and closing the window will take the change and everything is fine. However, I should only have to apply once and not twice in the green dot mode, particularly if I am changing several controls at the same time.
I tried the Control Change MIDI value and it works in either red or green dot mode. Making a change makes the Apply Now appear at the top left as usual.
Why doesn't the Apply Now appear at the top left for MIDI entries of the Sysex Property panel? I sense a few other changes have occurred in Mac OS, such as the convenient numeric keypad with upper case hex letters and V and L no longer appears as it does in iOS.
If Sysex Properties is selected, I suggest the Apply Now becomes a choice at the top left. The user then has the option to not make a change and select the go back arrow, make a change and have the change take when closing the panel, or Cancel, which does appear. At least if he made a change and didn't want to keep it, he has several ways out.
