lfm, I thought your CWBRN was fine. You explained what you were trying to do clearly. AFAIK Dimension Pro isn't going to send notes back to the host like you were expecting in your example, but I can see how that isn't obvious at all from your point of view. This probably could have been handled better on our end versus just pushing the case over to support to be honest. Sorry about that :/
I think what most likely gets people hung up on this is that a synth may expose that it supports MIDI Output, and therefore SONAR detects this and exposes it as an option, but it doesn't necessarily mean the synth supports sending notes, cc data, etc back to the host. In other words, as far as I understand it, the existence of the MIDI Out option from the synth doesn't indicate that all functions under the sun have been programmed into the synth itself. Maybe it sends one of those things, all of those things, or none of those things. It definitely differs.
I think some of the bugs people are perceiving are just features not implemented into the synths they are using when trying to test the feature.
Maybe what might be helpful is to start with something that we know sends MIDI out like Catanya, Jamstix, etc.. The demo in the video a few posts above using Reaktor is great, but a bit intense if you're not familiar.
Side note: that video is definitely helpful. Thank you for sharing it! I'm pretty sure we have documented cases of the behavior being shown internally. That's not quite the same thing that was reported in the CWBRN though, which seemed ultimately just trying to figure out how the feature worked in a broader sense.
Anyhow, I think there might be something odd about SONAR detecting MIDI Out as an option on what appears to be every synth. I'm not personally sure. I'm bugging people internally about it. Might not have an answer for a bit on this though.
