Although VMware synced, always, every time I saved to an external box It would give one of those electric bizzing sounds, and hang,
So, I investigated further, I have been letting Virtualbox choose the type of virtual drive, I figured that they knew what they were doing,
It turns out that the problem was in the type of virtual drive Virtualbox was using. VDI uses drive compression, which means it cannot maintain stream syncing.
I switched to VMDK and everything works great in Virtualbox, I seems that VDI is a product of Oracle, and it does not appear to be worth shit.
I had no idea it was the Virtual drive that is faulty. So, It is even syncing my midi player and the virtual keyboard, which is the first time I ever seen that.
So, I shit canned VDI, and VMware. and combined the best of both and got the best running virtualbox now.
I can Play Midiplayer 6, with Mysung, at 1.56 g file, and the box running on 2gb of memory. And everything stays in sync.
not bad.
