"When I download MIDI music from internet nothing happens", CTK496

the CTK496 would make some sound whenever it receives the note information

even without any setting on TonMap. It probably needs to check and see

if the USB-MIDI interface driver would install correctly and then PC

would detect the driver.

As for "I have TonMap=G but it always reverts to "00 PIANO 1" because I

don't

know which button to press next.",

does this inquiry mean the original setting value would turn into "00 PIANO

1" after reception of MIDI information?

If yes, the program change in the keyboard would work properly.

There would be possible trouble with the keyboard if playback won't go with

right installation of the driver and right MIDI-IN/OUT connection.
