[linux-audio-user] corrupted midi messages using vstserver

I have just got vstserver up and running (using the recommended ancient version of wine). The problem I am having is that some midi messages to the plugins get garbled. What happens is that, if I hit two or more keys simultaneously on my midi keyboard, one (and only one) of the notes will continue sounding after the keys have been released. However if I play a slightly broken chord (i.e. where the keydowns are not precisely simultaneous) I don't get the problem. The problem occurs, as far as I can tell, with any VST plugin that produces a sustained note (such as Synth1 or Phibes). However it does not occur with unix-native softsynths such as zynaddsubfx or xsynth. My midi controller is a DX7 and my soundcard is an Audigy2. Is this an old and known problem or is it something particularly to do with my (up-to-date Gentoo) system, or even with my hardware? Is there a solution? Would jack_fst work better? (if I can ever get it to work at all). Many thanks Robert -- Robert Persson "No matter how much ye shake yer peg The last wee drap rins doon yer leg."
