Hey, solved! I had success starting MrRay73 just with vsthost (from dssi-vst-0.8) rather than jack-dssi-host. Another problem remaining now is, that the midi-notes from my keyboard are one octave too high. I would need something, like a midi-event-processor, which i can connect in qjackctl and that transposes the incoming notes down, before they are routed to MrRay. Is it "qmidiroute", what I'm looking for? thanks, oz $ vsthost MrRay73.dll Returning file identifiers: i03kOP7u65hMEIJRLIjiQDfF DSSI_PATH not set, defaulting to /home/zi/.dssi:/usr/local/lib/dssi:/usr/lib/dssi RemoteVSTClient: executing /usr/local/lib/dssi/dssi-vst/dssi-vst-server -g MrRay73.dll,i03kOP7u65hMEIJRLIjiQDfF DSSI VST plugin server v0.986 Copyright (c) 2004-2008 Chris Cannam Loading "MrRay73.dll"...
