Hi Bob, Thanks for your reply. My Casio CTK-611 has Midi but I cannot see in the Midi Implementation Chart which MIDI functions will change the Tempo, Rhythm, Tone and Transpose. These are the only buttons I'm looking to "automate". The chart consists of 4 columns labeled FUNCTION, TRANSMITTED, RECOGNIZED and REMARKS. Under FUNCTION is listed Basic Channel,Mode, Note #, Velocity, After Touch, Pitch Bender, Control Change, Program Change, System Exclusive, System Common, System Real Time, Aux, Messages. The only function that has some specific remarks is CONTROL CHANGE. The remarks under CONTROL CHANGE are Bank Select, Modulation, Data Entry, Volume, Pan, Expression, Hold1, Sostenuto, Soft Pedal, RPN LSB MSB, All sound off, Reset all controller. None of this appears to be what I'm looking for. Any advise? - Ray
