This can happen with slow or very fragmented hdd and also if the audio buffer is too low.
Also, having virtual instruments in real time takes a lot of ressources. I usually use only one at the time and render the others to audio.

"...The recording stops at random times... / ..."I have no clue what makes Cubase cut my recording at random points while it still gets the sound signals from the 2i2. Any ideas on how to fix this or why it happens?"

It is very likely that you are running low on, or out of memory.

Look to PC's post as a good place to start. You could increase your RAM buffer as PC mentioned... but if you are attempting to do dense productions on a computer that wasn't built up to spec for that type of audio recording, it won't make all that much of a difference. You have to understand that multimedia production - both audio and video - are resource hogs. They will eat RAM and Storage space at a phenomenal rate.

And, if you have other processes going on in the background, like a constant connection to the internet, or apps that turn on automatically when you boot your computer, etc., then you are taxing your system even more.

For example, in Windows XP, you were limited to 4 gig of RAM. That's 4 Gig, period. And you can work with 4 gig, by and large, if you plan ahead and understand the inevitable limitations... But, the OS itself gobbles up almost 2 gig of that 4 gig right away, the minute you turn on your computer - and that 2 gig is needed to nothing other than to run XP. So... you're down to 2 gig of RAM right away, from which you now want to record... and adding various processors and effects to each track, along with VSTi's.... You are stepping up to the plate with a pretty light bat.

If you are working in a W7 (or later environment), you can add more RAM - IF your computer allows you to do so. If you are using a cheap, off-the-shelf "every-man's" computer, you are probably nowhere near where you need to be in terms of the processing power or memory that modern DAWS require to run in an efficient manner. Adding to running just the audio program itself, is the fact that you are also using VSTi's (soft synths), and they are very taxing on your system.

Questions:
What type of computer are you using? Which OS? Processor type and speed? The amount and type of memory (RAM) that you currently have? The size and speed of your internal HDD? Is this computer a stand-alone model that is off "the grid"? Or, are you continually running the internet in the background? Do you have a virus protection program installed , such as Symantec, Norton, etc? These progs are notorious for drastically slowing down your computer. When was the last time you checked your HDD for errors and ran a defrag? When was the last time you checked your computer for outdated or dead .dll (driver) files? You may have drivers resident in your registry that aren't even doing anything anymore, except for clogging your system and slowing things down...

Providing these details will assist us in helping you more.

Now that i think of it, it might be because my local drive is running out of space, my pc's HDD's are divided into 3 and cubase is recording on the most crowded one (the C: ) It might fix itself if I change the path it records the sounds to, i'll try that.

And for your question DonnyThompson:
I have Win7 Pro. (64-bit) as an OS, my PC is pretty powerfull: it's an asus g55vw, 12 Gigs of ram, and an i7-3630QM @2.40GHz intel processor.
I defragged my discs just today after i read pcrecords comment. I got Bitdefender as an antivirus, as you said norton slows your pc to turtle speed.

As I said, it's probably because my Local disc has only 9.69GB free left on it, while my other drives have 261 and 213GB, i'll try to change the place cubase writes to and see if that has an effect

You guys are amazing, i write here and problem gets solved in the exact same day, thanks for everything, i changed the path cubase recorded to, now i have infinite recording length, i just recorded about 5 minutes of silliness in one take.

Glad we could help. Pass it on. ;)

Glad it works. If you ever get a project so complex that the performance is failing. Try to unplug or disconnect from the network and disable the antivirus. It helped me many times ;)

A partitioned hard drive is SUB OPTIMAL. Get yourself another physical hard drive either internal or external. The rule of thumb is main drive for programs and OS. Second physical drive for samples. Third physical drive for recording audio. If you don't use samples cut out drive two. Store projects elsewhere on usb hard drives. Do not daisy chain pata drives. One header per drive unless you are firewire.
