I have a new Casio CTK 810 and installed driver and smf converter but cannot make a connection with my laptop and desktop, both Vista 32 bit........

You can find the software for Casio LK-70S here: https://support.casio.com/en/support/download.php?cid=008&pid=20 .Look for the driver for the keyboard under the Digital Keyboard/Piano (excluding the PL-40R). Select the appropriate link and then scroll down to the Download button. Another file is the SMF converter. The conversion software is here: http://music.casio.com/e/smf/ . Scroll down to find the download links. This software works with Microsoft Windows 98 SE, Windows XP (32-bit) and Vista (32-bit).

I hope this helps.

You need to get latest USB driver for Windows 7 (both 32bits and 64 bits available) at:

I think the SMF converter though is a 32 bits application will work on windows 7 provided the correct USB driver has been installed.

If you connect to PC using USB interface, then use a commercial midi player - e.g Melody Assistant or Harmony assistant to play MIDI files to it.

Or else download "SMF convertor" to convert midi files and download compatible file to keyboard.

Casio has this driver on their support page: https://support.casio.com/en/support/download.php?cid=008&pid=20 . Scroll down to the drivers section and click on the link for Digital Keyboards/Piano (excluding PL-40R) for 32-bit OS versions. This link is to the left. Currently the link for the 32-bit versions of Vista, Win7 and Windows 8 is https://support.casio.com/en/support/download.php?cid=008&pid=75 .

I hope this helps.

I have the same keyboard and it works...i had trouble installing the drivers cz it doesnt have autorun....what i did was plugged in my usb cable then when the bubble pops up saying found new hardware click onit and follow those prompts instead of opening the cd...once thats installed go to options/midi and you will see the keyboard there as midi be sure to click enable... remember that smc converter is not the installation fo the midi drivers so once u install smc convert your keyboard still wouldnt function as a midi hope that answers your question...

You need a MIDI to USB cable. I use the M-Audio Uno. I would recommend this--very reliable. Check it out here's the link: http://www.m-audio.com/products/en_us/Uno.html
This will allow you to send and receive MIDI between your laptop and Casio Keyboard.

Make sure the driver is compatible with your operating system... often stuff will not work with Vista for example. Often SOME software REQUIRES it to be installed before USB cable is connected, and yet other requires it not be connected till software is installed... read the manual...

Vista has SO MANY compatibility problems that it MAY be futile to try finding a specific driver for thaat synth. Consider going to Windows 7. HOWEVER, a MIDI driver is a MIDI driver and anything specific to the synth is really not truly just a driver as such, but a user interface type program that may contain things like voice editors and other functions specific to the synth.

http://support.casio.com/download.php?cid=008&pid=340&rgn=5 copy and paste or click for the software It should work with your Casio. Also check out this link http://music.casio.com/e/ and click on the link for SMF Converter and this takes you to this http://music.casio.com/e/smf/ READ THIS LAST LINK AS IT CONTAINS VALUABLE INFORMATION.

On reading specs, use of the USB is NOT supported on a MAC or on other than the 32 bit version of Vista. If you happen to have the 64 bit Vista, it won't work. All the other versions of Windows seem to be supported..

SOMETIMES one must install the software BEFORE connecting the USB cable to the unit. SOMETIMES one must install the drivers in SAFE MODE. These things are ridiculous, but some of the quirks of Windows are stupid.
