SOURCE: Casio ctk-496 claims to be midi keyboard controller

Try downloading MidiOx and troubleshooting with it. It will show you if you have any midi activity and which channel your Casio is transmitting on etc.

SOURCE: Can't get Casio CTK 601 / 611 to function as MIDI Contrller

I'm not at home right now where all my manuals are so I'll try to explain with out. You will have to set it so that the keyboard is the slave device. Try setting it to Omni receive. It has to be able to listen for all midi channels at once. You have to write a sequence on your computer and hook it to your keyboard by using midi out on the computer to midi in on the keyboard in order for you to use the computer as a controller. If you need the keyboard to create the sequences then you have to hook the midi send on the keyboard to the midi in on the computer play/enter your notes into individual tracks in your software then assign channels, voices etc to each track and save the sequence. Then when you hook it up the other way the sequence will play just like an audio recording except the sound w2on't be there. What you have recorded by creating a sequence is a series of midi messages that the keyboard will receive if you have it set properly and hooked up ptroperly which it will translate into sound. This is a minimalist explanation at best. You will have to have a better understanding of not only your keyboard but also your software and midi in general. There are some pretty amazing things you can do with midi. For instance if you have a lighting controller that is midi capable you can i,mbed all the lighting scene changes for your song in order on one track. You can also control your guitar effects pedal to change effects automatically while your playing. Once you get a handle on it you are only limited by your imagination and your budget. Hope this helps in some way.

SOURCE: looking for a schematic of the Casio ctk-700 to

The keyboard is LIKELY scanned as a matrix.

You have two problems:

The contacts in the Thomas will have to be totally disconnected rendering use of any of the Thomas organ unlikely.

The second problem is that the keyboard LIKELY has velocity sensing. This means TWO contacts must be used PER note. One contact "makes" first and "breaks" last. This is used for velocity sensing on synths. The Thomas foot pedals likely only have a single contact per pedal, and even if they had two, it is unlikely they sequentially close..

The matrix scanning is accomplished by sensing the connection of two crossing points on a matrix of circuit lines. USUALLY each of 12 wires tie to all of one note across the board. Then two other lines for each octave "strobe" the first make contact and then the second of those strobes the second make contact. There are two of these strobe lines for EACH octave on the board.

Remember that these lines scan at digital logic speeds so wire length and NOISE/STAIC DISCHGARGE PROTECTION is a must.

SOURCE: not able to connect to USB MIDI of my Casio CTK 810i

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.
