support midi options in midi learn wizard

[Marco Sampellegrini]

Hi guys,

I'm trying mixxx 1.11 on ubuntu 12.04 with a korg nanokontrol. There is no mapping for this device so I gave the new midi learn a go. It works fine, all controllers are mapped correctly, but only sliders and knobs are actually working. Looking at the generated xml file, I can't see anything wrong and the mappings for buttons are present.

I tried deleting the .mixxx folder and doing the process again to no avail.

Thanks
Marco

Launch Mixxx from the terminal with "mixxx --controllerDebug" causes the program to display/log all of the MIDI/HID/etc. messages it receives and script functions it loads. Could you try to check whether the messages it receives from the buttons from the nanocontrol are the ones in the xml?

Also there was this bug: https://bugs.launchpad.net/mixxx/+bug/995652
maybe your current 1.11 installation is affected, try to use the latest build.

I've compiled the latest version and got it working. The midi learn produces this code:

            <control>
                <group>[Channel1]</group>
                <key>play</key>
                <status>0xB0</status>
                <midino>0x21</midino>
                <options>
                    <normal/>
                </options>
            </control>

I had to change <normal/> to <button/> to make it work. Thanks for your help :)

Excellent Marco,i am glad that it works now.
How is your 1.11 mapping different from the existing 1.8 mapping?
See http://mixxx.org/forums/viewtopic.php?f=7&t=1999&hilit=nano

Would you mind sharing your 1.11 mapping either here on launchpad.net or in the dedicated forum thread?

It's not that different. I'm still learning the inner workings of mixxx, especially the scripting engine which is just amazing. I'll sure post back something as soon as I'm satisfied with the result.

Markin invalid, since the Point-and-Click-Midi Wizard works just fine.

We need to extend the functionality so one can change the midi Input tag options afterwards without diving into the xml code, similar to the Midi table what we had pre1.11.

IMO not invalid since the point and click wizard won't work for devices like the NanoKontrol which need the <buton/> MIDI option. Ideally we could let them check a box or something or do a 'verify' step that if the verify fails we could try switching from normal to button.

[RJ Skerry-Ryan (rryan)]

While I believe the <button/> is no longer needed (thanks to Daniel's change to fix button handling), the midi learn wizard now supports setting MIDI options.
