Newbie Question: Recording using Casio LK-240

[Eddie Kwok]

This is probably a stupid question, but I can't seem to figure it out. I got a Casio LK-240 keyboard, Audacity on my PC, and a USB cable connecting them. How do I record the sounds I played from my keyboard to Audacity? Am I missing anything?

Hej Eddie,
I think I can help you:

Audacity cannot record MIDI input, only audio input.
Casio LK-240 has no line out jack, so you can only connect the phones output jack with line-in jack of your computer.

If you are recording MIDI to your computer you will need a USB A to B cable if your keyboard has a USB MIDI port. You will also need a MIDI sequencing software like Anvil Studio or Reaper on your computer.

If you are recording audio output to your computer and you have no other audio out than the headphone jack, you will need a suitable cable with connectors from your headphone jack to the stereo input on your soundcard, however, since headphones are high current devices you will also need to put a 10 dB or 20 dB attenuator inline with the cable to reduce the output otherwise you risk blowing out your soundcard and your keyboard's headphone jack.

For recording audio you require a program like Audacity to record the music as a WAV file and then an encoder like LAME to convert it to MP3.

PS. Output connects to Line In on your soundcard (the blue connector) not the Mic in (red connector) and remember to place an attenuator inline with the circuit.

Here's an appropriate attenuator cable you can use in conjunction with the proper adaptors and extension cable.

You might try connecting an audio cable from the keyboard to the line in jack on the computer. You may need to point Audacity to the line in jack in edit > preferences.
