As for others users and why there seems to be so little interest in the VS-100, I tend to think it was marketed primarily as a "Sonar" interface (despite it's ability to act as a controller/interface for other DAW programs) so it never really caught on outside of the Sonar community which is a shame as I really think it is a great audio interface with the prefect set of feature to price ratio for most small project studio types.
@ Jind: That is a great observation! It's got "CAKEWALK / ROLAND / SONAR" all over it, which certainly will give the impression that it will only work with SONAR! The name SONAR should have never been on there.
Although I use X1 Expanded, I also do a lot of work with Studio One V2. The VS-100 works great with that DAW, when set to Universal Mode which was introduced with the 1.5 firmware.
@ Riny: Great avatar! I am a very big Chet Atkins fan. You also do not have to apologize for your English, it's a lot better than my Dutch

. If you know Amsterdam well - can you recommend a good hotel near the Central Train Station? The band I play with is heading to Switzerland & France for some shows in May, and decided to stop in Amsterdam for a 3 day visit en route.
