I will apologize in advance for the length of this post.
I have finally decided to ditch Gigastudio 3 after several years of (mostly) faithful service. The search for a workable alternative is on, and I must say that I love the LinuxSampler interface and what it's capable of. I downloaded the Kontakt demo and had trouble getting into it, but with LinuxSampler I dove right in. Kudos!
Now for the issues

1. Main Issue: I've created an Orchestra, a MIDI device, and an audio device as the documentation says (standalone mode). I'm able to load a .gig instrument and hear it play with the keyboard within JSampler. The issue arises when I try to get playback from Sonar 6. I've set things up all sorts of ways and I just can't get any of the notes to sound. I'm currently running with a Sound Blaster Audigy 2 and an M-Audio Audiophile 2496. I've tried both as the MIDI inputs for JSampler and the Audio out (setting Sonar accordingly), and can't get anything. What am I missing here?
2. The documentation suggests that an "arbitrary" number of ports can be specified within JSampler for MIDI input. As far as I can tell, though, the number of ports is restricted by how many ports your soundcard tells Windows it has... in the case of the Audigy, it's 2, with the Audiophile, it's 1. With 16 channels each, that limits me to a maximum number of 48 discreet channels, as opposed to 128 with Gigastudio's "virtual ports" that it creates (and are selectable within Sonar). Am I correct in this conclusion or is there some trick to having an unlimited number of channels? This is important as I would routinely use 60+ channels for orchestral scores.
3. When trying to load LinuxSampler as a VST within Sonar, I get "A fatal error has occurred" with Exception code c0000005, in reference to LinuxSampler32.dll. I've tried several suggestions involving copying a couple dll's into the same folder as the Sonar exe, but haven't had any luck. Has anyone else experienced this or have any suggestions?
Thanks for any help you all may be able to provide. I really really want this to work and to get away from Gigastudio once and for all.
