Expert Sleepers offers many products. Some of their product line is pretty confusing as to its purpose and functionality. The Disting does not have ADAT lightpipe capabilities as far as I know. However, it has tons of functionality. I hate the interface as it's not intuitive as far as adjusting parameters of each program. But the difficulty in use is worth it due to the tons of features. It's basically a Swiss Army knife for Eurorack. If you keep it in reserve and give it no full-time duties, it can provide that one missing ingredient. "I need an extra LFO, ADSR, ring modulator, compressor, etc..." for this one patch.
If you can dual boot your Linux machine, I'd add a Windows partition. As Lugia explained, you're not going to get the most out of your computer running Linux. It's always going to be a compromise over what's available. Booting it into Windows gives you tons of inexpensive options. There's a DAW by the name of REAPER that's quite extensive, inexpensive and hosts VST plug-ins as well. There are TONS... TONS of free VSTs out there that compete with retail. As Eurorack is quite expensive, having a low cost DAW arsenal at your disposal goes a long way towards freeing up cash for your Eurorack addiction.
The easiest way to dual boot your Linux machine is to use two hard drives on a switch. Select drive A to cold boot into Linux and drive B to boot into Windows. Or you could use the software method on one drive with two partitions. No disrespect to Linux. It's just not popular enough to compete in the DAW niche.
