Change input live

[albfan]

Connecting a complex midi controller (launchpad pro) this are the available inputs:

        o.midi.inputs.forEach((value, key) => {
          console.log("key:"+key)
          console.log("name: "+value.name)
        })

key:1A0CE1F47C19C43DAEB93B959...
name: Midi Through Port-0

key:E5906E7D3163139CD207E5D51A...
name: Launchpad Pro Live Port

key:A58AB652B0D1593D7240A7F8D4CD...
name: Launchpad Pro Standalone Port

key:90A8EE0861F31949F74E8BF58B07C75...
name: Launchpad Pro MIDI Port

So based on #49 I rework this to change live the input device
