Actually no, we're talking about ticks, but if I want two boys syhcned and with the same exact tone, switchable clocks are a go.

I see, so it means that having both LTC and switchable clock is pointless...
Thanks!

the slave DMG gets ticks from the master and follows those ticks.
So it doesn't get a BPM number and plays at that speed, that would cause the DMGs to work at a different speed.

Basically, a halfclocked DMG slaved to a normal DMG running at 120 BPM will receive ticks like it's playing at 240 BPM

so they will run at the same speed, but don't use too much tables

Hello there,

I stumbled upon a couple of problems while experimenting with oscillators.

I wired native one with 7.3 one through a 2-position key. When I switch between them the image freezes. If I reset the boy - it works fine with either crystal.

Another problem I'm trying to penetrate is how does GB synchronization works (via link cable I mean). If I try to sync underclocked guy with the normal speed guy - what happens?

I wonder do I need both LTC1799 and switchable x1/2 and x2 crystals. If synchronized boys need to have the same *exact* frequency, then switchable crystals may come handy. Thanks!
