hhmm, your midi lights are on, but you're not recording midi. Check your preference settings. It's been a while since I've used Reaper, just trying to remember. Reaper is an xlnt DAW. Make sure your track settings are set right. I think with the 1010 and reaper it would be an ASIO input. Check your settings, channel assignments and all that . More often than not, when an update is added, the settings on your DAW goes bonkers. I now use Samplitude and Studio Pro 7. With both of these I've set up a "Template" for recording. This Template I use use has 4 midi tracks and 24 audio tracks. I can always ad more tracks if needed. There's no way to tell what's going on without seeing what you've got going on. But it sounds like it could be a problem with your set-up. I've sometimes gone back to a previous recording, see if I can record on that recording, checked what everything was set at and then used those setting for a new recording. Sounds complicated, good luck.
