If I plug my Tele into the 2i2 and record something in Reaper, the level I see (in Reaper) while recording will be the level I see when the track plays back. No problem. But if I want to use some FX, such as when recording vocals, then the level I see while recording will be one thing (averaging -18 dB, no peaks above -12, the usual) but the level I see on playback will be much higher, sometimes hitting into the red. I've asked about this in the Facebook Reaper Users Group and a few snags have been cleared up but I still have the same problem. Same with recording guitar using any FX (I mean plug-ins): Reaper only tells me what the level of the signal is WITHOUT FX, but since I want the FX (sometimes) to be recorded, I need some way to know what THAT level is. Before I record, I mean. Finding out only on playback---AFTER recording---is finding out too late to do anything productive about it. I suppose this is a simple thing. So simple in fact that people can't believe this is even happening. But it is happening. Persistently. I don't know what else to try. I keep watching videos but they all talk about setting levels by seeing what the meter in Reaper shows. Fine, but if that's not the level of the signal being recorded, it's not useful. Indeed, it's deceptive: it suggests one's level is just fine when it is not!
