Hi Casio Gurus, I want to buy one of the Casio Light Up keys 'training mode'. I want to use my own 'training songs' I want to send or load my own Midi files to operate the lights without playing the notes and not have the notes light when I press them. I dont need to select just the left or right hand (I can make seperate midi files if I need that option). I dont need to use the advanced training features - all I want is the LEDs to come on when the MIDI is sent to the keyboard (whilst the sounds come from keyboard key presses). From the great U-tube, I understand this is possible with the LK 280, is it possible with any cheaper LK? Excuse the number of I's. Please advise which models (including out of production models) as I understand the LK120 is the only LK still being made and that has no input option (no sd card, no Midi, no USB). Any other keyboard make/model considered! Thanks in advance... K
