I used this rig over the summer to record the band's performance at Promise Keepers events (two days each in 10,000 set arenas), mixed and replicated on the spot for sale at the end of each event.
Toshiba laptop running Nuendo
2 RME pcmcia cards feeding an RME Multiface
4 Behringer ADA 8000 pre/converters lightpiped to the RME's.
2 Pacific Pro Audio firewire drives (one for backup).
A pair of KRK V4s'
32 channels in split off the monitor console.
32+ tracks, sometimes continuously up to 2 hours at a time without a single hiccup, week after week.
Mixed "on the fly" with a slew of plugins and automation then rendered and a master sequenced and burned using CD Architect.
The Behringers actually sound very good and are an incredible value for the money (about $200 each!) They survived the airlines in a 4 space SKB case without a problem. The KRK's traveled in a Pelican case.
I would check the SKB case, monitor case and board the plane with a carry-on containing the laptop, drives, interfaces, cables and clothes for the weekend.
The best performances will be selected and studio mixed "for real" for a live cd on Maranatha! records later this year.
On another note, I have a larger, rack-mounted PC rig (with Uad-1's and removeable SATA drives) also running Nuendo
which I use for studio tracking/mixing album projects. It travels in an anvil flight case as well as a two space carry-on soft rack containing an Alan Smart compressor and a Finalizer. This has worked flawlessly also.
Finally, if you plan on air travel, watch out for the dreaded 50 pound limit, carry spares (like another app drive and record drive),
keep it lean and mean and a DAW will work great.
