Rendering problem (maybe not a bug)

Hi when I render to stem a track with, say, a MIDI clip on it, it takes a long time, almost 4 minutes for biggish projects, even if the track being rendered only contains a few seconds' worth of MIDI data. What's even more surprising is the wave display form in the status window does not correspond at all to the track as it finally appears in the timeline once rendering is finished. I actually get the impression that Reaper renders the whole project, even though in the end I am left with only the actual track I wanted. Is there an option I have missed somewhere? It wastes a lot of time when all I want is to quickly but cleanly bounce to audio a short midi clip. thanks d

IIRC rendering a stem track always renders the track over the entire lenght of the project and so you're rendering lots of silence for a short MIDI clip. Why don't you use (r-click the MIDI item) "Apply track FX to items as new take" instead? :)

OK this is perfect, just what I was looking for. Any idea though why Reaper takes so long to render/bounce a full track (once again, alsmot 5 minutes for a track without much midi data on it)? I don't mind having blank portions on the track, I can always cut them out, but the time it takes is just too much. It seems strange that rendering individual tracks should last as long as rendering the whole project.

Hi Dacaumodo, Did you have a close look at the rendering options? -Data

similar issue, only worse 

I've been having a similar problem. When I render to mono track it will sometimes come out as a stereo track. It will show the waveform in the track but when I play it back there is nothing but silence. The BIG PROBLEM is sometimes when I render a track (stereo or mono) the resulting render will contain the waveform for a totally different track (one that wasn't selected to be included in the render) but when I play the rendered track it will play what I was rendering initially....if that makes sense. It's like this, the rendered track will be 2 minutes of audio, no silent areas, yet the rendered track will show mostly silence and maybe a 10 second long wave form which will be identical to some other track in my project..but when played, all of the audio is there, even during the visibly silent areas of the waveform. At first what I would do is immediately Ctrl-Z back to before I performed the render but when I do this, the randomly chosen 10 second track that the rendered track mimicked IS TOTALLY GONE FROM MY PROJECT! The physical track where that audio previously existed is still there, with all of my audio and pan envelopes still intact, but the audio is gone. I know this shouldn't be the reason, but it all started happening when began using a SCSI drive as my primary drive. I've re-downloaded, reinstalled reaper 3 times but the problem always comes back. Another thing, sometimes the rendered track will be EXTREMELY SLOOOOOWWWW and contain all sorts of...what could best be described as artifacts, little sound fragments that I know I've never recorded in my life....like some weird AM radio feedbacky high pitched whistling garbled sounds. Effing Strange. This occurs whether I'm using effects or not.
