The Yamaha MMP-01 is a Music Pad dedicated to creation of music, and features a matrix of buttons whose functions will vary according to the software being used, and its matching sheet.

It originally comes with the MPS-01 Music Pad Sheet, and other sheets are available.

Official price: ¥19,800


It might look like a huge touchpad at first glance, but in fact it uses the MSX-Paddle (PWM) protocol to transmit its coordinates, like this:

1 PWM0 X coordinate
2 PWM1 Y coordinate
6 Digital Sense

The sense signal indicates that a button was pressed. Only when sense=0 that the MMP-01 will update the X and Y coordinates so the software can read them.
