Reply to On Stage & In The Studio | What Works

Hey guys!
My brother and I are looking for gear to use in the studio and at gigs.
We were looking at buying a Maschine and a Push.(we want to get into live performances)
I was wondering what would be the best option soundcard wise and what would be a good way to have our sessions MIDI synced(It would be between 2 PCs ). I know Maschine has MIDI I/O but Push doesn't.
