Hey Dudes: Bit of a recording newbie. Im more of a metal songwriter than a production dude; currently in the process of recording some home demos and trying to get a better sound of my home recordings. Anyway, judging by my research, this is a common issue, but none of the answers that Ive tried are working, and Im having a hard time finding a thread that is a big lighter on the technical jargon. Maybe that cant be avoided, but here it goes. Currently using Reaper as my DAW. I am making extensive use of VSTs for my guitar sounds, and Im grouping tracks as much as I can to conserve processing power. This is currently my chain for rhythm guitars: TSE 808 (Tubescreamer VST) LePou LE456 (amp) LeCab2 (impulse loader) For leads I am using a similar chain, except with an AmpLion Mesa sim instead of the LePou plugins. It doesnt need an impulse loader (has a cabinet sim built into it) and sounds great. Anyway, I have created a master track with my VSTs in the effects chain, and created two tracks: one hard left and one hard right. As soon as I group them together, the panning stops working and everything gets squished into a mono track. Before you dudes ask, yes, I have switched all of my VSTs to stereo mode. The problem is with the amp sims themselves. When I leave just the TSE 808 on switched to stereo mode, the panning works fine, but as soon as I engage the amps in the master track FX chain, the panning gets squished to mono. The problem persists with both the LePou and the AmpLion. I have tried switching to panning to stereo on all Reaper tracks as well, and as I mentioned all VSTs are switched to stereo mode and I still cant get my grouped tracks to pan correctly. Dont think its my interface because as I mentioned, the panning works fine when I leave just the TSE 808 on, Any ideas? Every answer Ive looked up for this particular problem is not fixing it. Thank you all so much!
