The CTK-850IN can save MIDI data to an SD memory card or output MIDI data from its USB port to a computer, but MIDI data is exactly that - just data.  It is not "sound" (audio) by any means.  Per your stated criteria: "without changing its sound quality, to any external device", MIDI data can only do this if it is imported into exactly the same make and model as the source of the data; in this case - another CTK-850IN, as only another CTK-850IN would have the CTK-850IN's sound engine.  No other MIDI sound module would produce exactly the same sound.  So, for you, that leaves only audio, but the CTK-850IN does not have the capability of saving its output to an audio file for export, either internally  or to an SD memory card.  Therefore, you will need to connect its PHONES/OUTPUT jack to a computer's MIC/LINE-IN jack or to a computer audio interface unit with the appropriate adapter cable(s) and record its output with DAW or audio recording software.  An alternative would be to connect its PHONES/OUTPUT jack to an external recording device - here again with the appropriate adapter cable(s):

 

CTK-850IN (PHONES/OUTPUT) -----> Computer MIC/LINE-IN (Computer running DAW or audio recording software)

 

CTK-850IN (PHONES/OUTPUT) -----> Audio Interface Unit -----> Computer USB port (Computer running DAW or audio recording software)

 

CTK-850IN (PHONES/OUTPUT) -----> External recording device (preferably digital)

 

In all three of the above cases, the CTK-850IN's PHONES/OUTPUT level is considerably higher than that required by most recording devices, so you would need to keep its main volume control at a fairly low level to prevent over-driving the recording device's input.  It also cuts off the speakers, so would require using the recording device's output as an audible monitor.  For a computer, depending on its processor's capabilities, there could be a disturbing latency delay between the time a key is pressed and the output is heard, so I would recommend starting with the first arrangement.  For this, you would need only an inexpensive 1/4" (6.35mm) to 1/8" (3.5mm) adapter cable:

If you do not already have DAW software, I would recommend Audacity, as the basic version is available as a free download, and is very popular, so peer-to-peer support is readily available:

If you do not experience latency with this setup, then you should be able to move on to an audio interface unit (with appropriate drivers) in the future, for a more professional setup, without fear of latency:

If you do experience latency problems that can not be resolved with selection of proper drivers, your choice would be to move to a computer with higher processing power (speed), or to a zero-latency external recording device:

An advantage to an external recorder is that most can be battery powered, if necessary, to eliminate the USB ground hum that is sometimes present when connecting keyboards to audio interface units.  A less expensive option would be to record your play to the CTK-850IN's internal memory with the Song Recorder (Casio-MIDI) with no latency, and then play that back as you record the keyboard's output with one of the first two set ups. Any latency at this point would be of no consequence, as you would not be trying to play and listen to the output at the same time.

 

Best of luck with this !
