Everything sounds mono!

Everything in reaper sounds mono even though both channels of each track are lighting up active. This includes MIDI files and imported wav files that are definitely stereo. Any help is much appreciated. And no i don't have the master set to mono :)

midi files have no sound so it must be the output of the instrument, your track, your master channel or your soundcard or maybe your speaker. Have you tried loading a new project with a test tone generator and panning int?

Have you made extra sure in your options/preferences/audio device settings that you've got at least two outputs allowed?

[QUOTE=faun2500;1237928]midi files have no sound so it must be the output of the instrument, your track, your master channel or your soundcard or maybe your speaker. Maybe it has something to do with my sound card? Everything else on my computer is in stereo. I could listen to a wav file in media player that is stereo, import it into reaper and it becomes mono.

What audio interface (and driver are you using)? Do you use different drivers for Reaper and Media Player? does the interface have it's own software mixing panel (might be something in there)? can you post a screenshot of your IO on the master and your audio preferences?

Make sure width is set to 100% for your master track output.

oops sorry 4 in the morning. here are those screenshots.

thanks, I was basically asking what audio device you are using to listen to stuff, your answer indicates that it's an onboard soundcard of some type. Maybe, just for interests sake, try downloading ASIO4ALL and using that as your driver instead of the WaveOut native driver. Also, if you click 'view'->'master track' you'll see the master pop up. The IO I was interested in was from that one, not the track with the midi on it.

To test if your output is stereo, just test REAPER's pan knobs while playing back your track. MIDI pan don't affect track pan, I assume. Most VSTI's probably don't have that MIDI pan CC in them. I always use track panning, BTW. Anyway, if your output really is mono with width 100% active you will notice this with track and master pan control knobs.

Let me give you a tip here mate. Don't use midi CC to control a synths pan. (unless your really, really need to do it this way for a specific reason. Just use automation. Instead of controller the synth pan automate the track pan, pre or post-fx.
