Reaper not recognizing more then 2 inputs from Interface (FIX)

My issue is seemingly simple, but none of the other threads about this issue has helped solve my problem. Basically, I am using my Scarlett 18i8 | Focusrite as a control surface. I have 4 microphones plugged into it that I want to record my drum set with, but I can only get Reaper to recognize two of them (at a time). I will concisely summarize what I am noticing: When I select the BR-800 via the Control Surfaces tab in Preferences, the Br-800 inputs and outputs are named "2-BR-800"; I'm assuming this is indicating there are only two inputs being recognized? inputs (and I configure them properly w/ the routing), they are recognized fine; Also, when I select the 4th mic individually (it only lets you do this with the 4th mic), it comes through fine. However, when I turn on 4 track recording, Only the first two mics are recognized (I am assuming it is because it is technically not in mono anymore? or maybe Reaper is only set to see 1 or 2 mics at a time?) The last 2 microphones are still audible through the program, but they simply will not be recognized/recorded by Reaper. I was getting a message from Reaper claiming that the input/output ports could not be opened, but I accidentally turned that error off so I can no longer tell if I Reaper is still doing this. Adding more inputs or outputs under "Device" does not seem to do anything. I tried reinstalling Reaper (I think twice?), but it apparently did not alleviate the issue. Besides Reaper ignoring the other mics, the BR-800 seems to work fine with Reaper; it controls the faders fine; pressing play, pause, restart, record, etc, triggers the similar function within Reaper. The weirdest part is that I am almost certain I recorded three different mics on the 4-track record once when I first downloaded Reaper, but it is possible I only recorded two mics and one of them was recorded twice. I am sorry this post was super detailed and convoluted, if you would like to me describe something more simply or elaborately don't hesitate to ask. I have installed a VST (Ez-Drummer 2) and used my ME-80 within Reaper, so if you believe those could have some impact on Reaper's functionality I'd also be happy to describe what I've done with each of them. Reaper not recognizing more then 2 inputs FIX. Reaper not recognizing more then 2 inputs from Interface (FIX).

You're a legend- I wasted a few hours over a few days looking at Reapers useless tutorials wondering what I'd done wrong that it would only pick up two tracks. I was just about to throw it in when I found your saviour of a video; Thanks so much!!!

"And that's the reason I'm makin the video" cracked me up. Subscribed.

[@copykon]

You my man, are REALLY fucking awesome!! No plugging for your channel, No endless fucking yapping and right to the point in just one minute and fifty seconds. THIS IS WHAT EVERY CHANNEL SHOULD BE!! AGAIN, YOU ROCK!

[@marzunknown]

Thanks so much for taking the time to make this video! Really helped me out.

[@Moparornuthin]

Helped another ! Hours and hours of other videos and you solved it in 30 seconds. Thanks !

[@mikkellee1751]

Incredibly helpful! I very much appreciate the time you took to save me the time troubleshooting this issue!

[@sensedata4908]

What a star. Just THE best and most helpful video I could get as I was in deep trouble.

[@Novasonsofficial]

This was so much help to me man! Thank you so much for uploading this. You saved he day brotha 🤘🏻😎🤘🏻

[@jongorrotxategi5239]

Thank you very much. I'm using 8 inputs to record some drums and this explanation was really useful.

[@futzpah]

Thank you!! I searched many videos and this is the one that solved it! I recently upgraded my interface with a Tascam 208i and I switched from Acid to Reaper software. So many new options I got lost in the interfaces. Now I can finally assign all my mics. Thanks again!

[@docf.n.t.2310]

Thank You so much. I was tearing my hair out trying to find a video like this. Google was hellbent to sell me another 8 channel interface ! Can even remember anymore how I asked it to get here ! I might have eventually tried this anyway, but it would have taken me considerable time to get here. This video saved me many hours, & much stress (I have a heart problem, so stress is BAD for me !)

[@xCaffeine_Fiend]

Thank you! easy to follow, and solve my problem.

[@GeoffRobb]

Thank you - this had me going crazy for half an hour!

[@sorrytopart]

Thank You..straight to the point. Worked great for me.

[@RonRhodesVO]

Brother, you just saved a lot of profanity-loaded frustration. Thank you!!!!

[@futzpah]

Over 6K views and only 130 likes!?!? Anyway, thank you for posting this! I did a hasty change to Reaper and didn't have a lot of time to adjust to the interface. This was stumping me as my DAW has 8 inputs. Quickest and easiest explanation I could find was right here. Thanks!

lol tks

[@BNWiremu]

Thanks got me to

[@soundblaster2009]

thanks

[@poweryourself8101]

I was having trouble with the Scarlett 2i2 where it stopped giving me the options for selecting Input 1 vs Input 2. Even doing the things in your video did not solve it. The only work around i've found is by displaying the Routing Matrix. It is found under View and you just select Routing Matrix and it will bring up a diagram where you can actively change the input associated with each track (Red dots). Definitely something changed in Reaper the last little while as I used to be able to select it from the track directly. Needs to be fixed.

[@ericsmeal3459]

question, what were you recording?

[@bretts1]

Danny i been missing your videos I thought u fell off a roof. I went to Southern Ideas thought u were moving there? Is this u main channel?

[@deepsouthvideos7120]

LOL no,,, video soon on Southern Ideas

[@holidaymaker2982]

👍

[@kewldeal]

the enable inputs button is not there for me...

[@AbsoluteMalarkey]

Mine isn't showing any more than two options

[@BMU5]

Where in Pro tools can do this?

[@nathanfeuerberg]

So, I was like only an idiot wouldn't realize this. I've been using Reaper for years. I know how this stuff works. Well, I went into preferences and realized I hadn't selected 8 inputs.
