Allow to manage MIDI clock routing, select which device is clock master and which is slave

[christofmuc]

Currently, there is no single place to choose which device is set to be the master clock, and I actually have multiple cases. Sometimes I want the drum machine to do it, sometimes the looper pedal. Sometimes both are turned off and I want the synth to be the master.

This can easily cause multiple MIDI clocks to be turned on at the same time, causing havoc.

Idea: Show a screen with a list of all synths that can generate a MIDI clock, and allow to turn them on and off, respectively do a Radio button that turns one on and all others off.

Also allow to set clock to slave mode. Not sure about the start/stop behavior.

Also measure on and show on which MIDI interface a clock is received. That would be important to know if the turn on/off worked, or if some other device is sending clock.

This is a bit problematic with MIDI patch bays like the Motu midi express XT, as that has a single "sync interface" that collects all clocks from all interfaces, and you cannot detect which port actually receives the clock.

It should have a clock measurement built in to show the clock received.

It could have a clock message translation function for the Boss RC-300 so I can finally slave that unit.

What I need is a MIDIClockCapability, with the following functions:

• List supported clock modes
• change supported clock mode
• get current supported clock mode

I think the clock modes are probably easy and everywhere the same. Maximum I think:

• Master (Internal)
• Slave (External)
• Off
• Slave no Start/Stop
• Slave passthrough
