Sysex Beamer let's you copy the display contents of Yamaha keyboards (Tyros 1 bis 3, PSR 3000, PSR S-900 / 910) into a graphics file (bitmap format bmp).
To do this appropriate system exclusive messages are sent over a MIDI connection.
The graphics will then be created on a storage medium attatched to the keyboard.
The software may be enhanced easily to support new models.
In fact you may extend it to send system exclusive messages for any purpose you like.
For testing and education purposes you may type and send ad hoc system exclusive messages.
