Hi, new user here. I'm using the PC3LE8 keyboard.
I was just wondering something about syncing to an external midi clock.

After much difficulty and watching a number of vague youtube tutorials, I finally found out how to sync to an external midi clock.

So first you have to set the Tempo parameter in Song Mode to Ext and make sure the song is Looping. I mean, what? Why is this necessary?
And then you can edit a Setup to change the ClockSource in COMMON to External.
Now this works reasonably well (minus a few irritating glitches and a bug with LoopWait/Loop for the SyncTypes).

But is this the only way to do it? I use my keyboard mainly in Program mode, because I find it a lot clearer to use than Setup mode. If I want to record something or make a sequence I use a computer or external tools. Is it possible to Midi sync in program mode and make sure arpeggios are synced? I mean this seems to me like an extremely common use case. Because if I just want to play some quick arpeggios to a drum track or something, I want to be able to do this in Program Mode and not in Setup Mode, where I would be busy for a half hour making sure everything is set up right and assigning all knobs and pedals and stuff to the correct filters/effects/etc.

Thanks for the feedback! Glad I found a forum for Kurzweil stuff, because there is very limited info available online.
