[LAU] native linux vsts (esp glitch)

Hi I recently bought energyXT2 (commercial, native linux daw) and now I'm looking for vst plugins. It seems that the program could be run through wine (supporting windows vsts in dll-format), but somehow I have the feeling that running the native version is faster and should be more stable. So my questions are: 1) What would must-haves native-linux vsts (I have freeverb, the mda's and the loser-plugins + a few more)? 2) I contacted the author of glitch (http://illformed.org/blog/glitch/), which seems like a really cool tool, asking if was interested in providing a linux version of glitch. Can anything in general be said regarding how hard it would be to supply a linux version? I guess it's not only a matter of under compiling, right? I'm willing to help as much as I can, but my programming is no that great, are others interesting in helping, for instance by porting glitch, should the developer be willing to play along. 3) I know there are some non-free issues with vsts, but what exactly are those, and provided I'm right in assuming that the linux audio (dev) community has a negative attitude vsts, what would the main arguments against it be? 4) Anyone here using vsts (both native and windows)? If so how do you use them, in which hosts, and with which benefits/problems? Who do you use them over dssi or ladspa alternatives? Looking forward to hearing from you! -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk
