My setup goes engl e530>blackjack onyx>reaper/wall of sound. I open reaper, load wall of sound, arm everything and get going. Half the time I can't get it to monitor the WoS tone, and then when I playback a recording it will have the WoS tone, even let me tweak the settings. The other times, I can't get it to record sound at all. I realize I'm not working with very much processor power at all, but it's more than the required for both reaper and wall of sound. I'm about 2 days away from just saying fuck it and buying an sm57, and giving up on silent recording altogether. I'm using Audio Technica ATH-m40x's. I've tried both the headphone out and monitor outs on the interface. I've tweaked pan settings, input settings and I just don't know what to try next.
