I have a casio lk-44. I want to be able to play a song from the songbank, but just hear the background rhythm and not the melodies. I want to play the melody myself from the songbank. When I pick a song from the songbank the melody plays along with the rhythm I can't turn off the melodies. I can't find out how to turn off the melody in the songbank from the booklet that came with the keyboard. thanks Jim

You can't add songs to the LK-30 song bank. I suspect you would need to take apart the keyboard and replace the ROM (read-only memory) chip to get a different song collection.

Most Casio electronic instrument manuals are available from http://support.casio.com/en/manual/manual.php?cid=008 . However, I found the LK-30 manual at manualslib.com: https://www.manualslib.com/manual/358460/Casio-Lk-30.html .

I wish that I had better news for you.

EBay has the Song Book for the LK 43/44 (which may be the same) so it's worth checking there from time to time.

The answers will be in the manual. Here's a link

Casio LK70S User Manual

you nearest casio dealer may have one in the back of the store,
many buyers don't want/need the manuals so some stores hold on to them for such occassions

Read your user manual about keyboard split. OFTEN the rhythms use the keys below F sharp for the chording of rhythm. When in this mode, you should restrict your melody to notes above F sharp that is to the left of middle C. If you play melody below this it will confuse the rhythm chording. You can likely change the split point of the keyboard, however, the F sharp split is the standard and I would suggest staying with it.

You can play back standard MIDI files from the SD card slot, or load them into memory via USB. However, it is not possible to add new tones or rhythms.

Read your manual regarding "fingered chords" and similar subjects. It sounds like you are in a single fingered chord mode...

I could not find the schematic for this, but other Casio units use a common voltage regulator amplifier chip to drive the speaker... I would firsst check that leads to the speaker have not become disconnected.

It is possible to load new rhythms and tones in the CTK-5000. But you need the stuff. That is what it really lacks. Casio needs the Rhythms and tones in its own formats.

If you have the smart card slot you can save your songs to the memory card by using Anvil Studio which is a free program. Save your midi song in Format 0 and be sure to use channel 4 for right hand playing and channel 3 for left hand. Be sure to keep the file size under 80k if you have other channels active for other instruments!
