Hey Troy,
It really seems you may need to take some time to watch some videos and look into the DAW (CUBASE) you are using. It can be quite complicated at first.
You are hearing 'popping' yet no input into Cubase yet? That sounds like a different issue....
Ok, FIRST, go
HERE and make sure you have the correct driver for your interface and system (W7 64-bit, or 32-bit, or mac or...)
I am assuming you are on
a Windows machine, so go to Start>
Control Panel>Sounds. Select the US1800 as your default input and output device. Also, you should disable system sounds there. They can piss you off later.
Now, here is where you need to pay attention to videos on initial setup for Cubase. It is imperative that you learn the steps to enable specific bus for each track that you create in Cubase. Then, you also have to enable the track monitor to hear what you are recording, as well as disabling it to hear it back after you record. It seems you are missing one or a few of these steps.
Don't worry or feel like you need to stress out here. It is common. You just have to sit back and learn what needs to be done. It will make complete sense very soon.
I will post here a setup thing I wrote to someone else previously. I hope it helps:
You must first select the 1800 in Cubase. Devices>Device Setup...VST Audio System. In the drop down menu at top, select 'US-1800'. While on that page, check the 'Release Driver' box. This will allow the 1800 to play WMP, Youtube, whatever, while Cubase is open.
Now, go to Devices>VST Connections (F4 shortcut). Add a mono input bus. You will need to create a input bus for each input needed from the 1800. For each input bus created, you will left click on the 'Device Port' column (highlighted in yellow), and select the input channel of the 1800 that you wish to use. Leave the default Stereo output bus.
Now, create a track to record to. Project>Add Track>Audio>Mono.
In the 'Inspector' window at the left of the main project window, look for
a symbol that looks kinda like this: >] SEE ATTACHMENT
This is where you select the bus you created in VST Connections. You will change this on each track that is using a different input channel on the 1800.
If you don't see the symbol, click on the track name at the top of the Inspector window to pull to the main Inspector screen.
You will need to also toggle the monitor button on the track to hear the input (it looks like a side view of a speaker). Toggle it back off to hear playback.
--to make this toggle automatically; File>Preferences>VST. In the Auto Monitoring drop down menu, select Tapemachine Style.
Let me know if this gets you up and running.
