Like many other models, the CT-S400 has a 48 part sound engine divided into groups. 16 parts are for keyboard local control. Another 16 parts are used for MIDI input. These two groups are independent. Unfortunately MIDI can't control the keyboard parts on this model. It's mainly intended for playing back MIDI files or used as a sound generator for software sequencers. The MIDI manual has more information on this architecture. https://www.casio.com/intl/support/electronic-musical-instruments/manual/?model=CT-S400

You could download an audio WAV file and copy it to USB flash drive and use the audio recorder playback function. Store the file in the MUSICDAT folder and name it "TAKE00.WAV". Replace 00 with another number if that's already used.

You may need to turn off "display chord names" to enable left right customization.

PDF version is here. It is possible to zoom in on any part of that to increase size. I keep Casio PDF files handy on my phone for helping forum members. It's easy to search key words and zoom in on specific parts I need to see.

You can connect the audio output of the keyboard to a computer and record playback of the song with software like Audacity to create an MP3 file.

What type of file are you transferring?

CT-S500 and CT-S1000V are two current models with sampling function.

Drivers are not necessary.

Error message codes are indicated by lights as shown in the full user manual error messages chart, page EN-43. Are you seeing one of those codes?

Casio Music Space will work with your WK-245 for the purposes of music learning, however the app itself is only compatible with Android and Apple devices. To use the keyboard with MIDI compatible software on a computer, connect a USB (standard printer type) cable to the keyboard. Windows will automatically detect the keyboard as a MIDI device. Any software you use capable of using a MIDI device can be configured to use "Casio USB MIDI" as the input and output device.

To save multi track recordings as standard MIDI files, use a USB flash drive connected to the device port on the keyboard. Press function>media>save>mlt R SMF and proceed with the menus to save the song. Note that a MIDI file can only contain 16 tracks maximum. If the 17th system track is recorded along with the 16 solo tracks, only the solo tracks will convert. If solo tracks are empty, the 17th system track will convert.

Are you looking for record audio from the keyboard? or MIDI?

Turn on auto resume to store settings during power off, found in the function menu, sub menu "other".

It sounds like you're using the correct key combinations. Do you have prior experience using various temperaments on other instruments? Differences in various tunings can be subtle or virtually indistinguishable depending on the type selected and chords played.

It's a standard USB printer cable if you're looking around for one.

Two USB ports are on the keyboard. To be clear, are you connected to the USB type B (to host) port?

Try blowing air between the problem keys.

That's something I call the accompaniment standby tone. With accompaniment chord mode turned on, but a rhythm is not playing yet, the standby tone confirms chord mode is tuned on. If the tone wasn't there, silence may be mistaken for a fault. Unfortunately the tone can't be changed to a different type.

The 17th system track is used to record your registration setups, splits and layers.

Best quality will be with the cable instead of wireless.

Press function, go to system, go to auto resume, turn it on. This remembers most settings for power off.

I updated the title for clarification

Yes it does. What are you referring to?

Sorry I didn't see your update. I was expecting a new post. I've never seen a pedal with adjustable tension before. I don't know how that would be done.
