support decimal input/display for MIDI related features

[Be]

Decimal numbers are easier to work with for humans than hexidecimal. It would be nice if Mixxx could display MIDI values in decimal when dumped to the debug output with the --mididebug command line option, use decimal in the XML mapping files, and use decimal in the GUI mapping editor.

I think this should be the default behavior, with hexidecimal as an option that would have to be intentionally selected.

For more technical folks, MIDI in decimal doesn't make sense. So it's a conflict between novice and advanced users. I think we can easily make improvements by showing both "hex (decimal)" in the GUI and supporting either hex or decimal input.

[Sean M. Pappalardo (pegasus-renegadetech)]

Even for non-technical users, device MIDI specs are usually given in hex. (I have seen some in decimal though, so it would be ideal if we supported both.)

[Daniel Schürmann (daschuer)]

We already support hex and decimal inputs in our mapping files.

Do we have an real bug report that our current debug output was causing confusion?

IMHO it is all about read the output and copy it to the xml file.
A "hex (decimal)" output is just redundant and might cause more confusing.

What is the use case that requires a conversion?

[Sébastien BLAISOT (sblaisot)]

sometimes controller MIDI documentation is in decimal.
see for example page 22 and further of http://ts.hercules.com/download/sound/manuals/MP3_E2/01_DJ_Control_MP3_e2_ENG.pdf

this is really anoying and risky when working on a mapping to have to translate all decimal from the manual to hex

[Daniel Schürmann (daschuer)]

There is no need to translate. If you have a doku like that, you can edit the mapping in decimal.
If you have a similar doku in hex, you can edit the mapping in hex.
If you do not have such a mapping, you can edit the mapping in hex, copied from the controllerDebug output.
