Hi Daniel,

Assuming, that you have tested your laptop’s audio and headphones by playing an ordinary CD, I agree with David that your problems are the use of the XP wave table. Your keyboard is a Yamaha keyboard while the XP wave table is a Roland wave table. The solution is to get of Yamaha a software synth or wave table that suits your keyboard. Nothing else will do, unless you are prepared to do a lot of experimenting and editing.

The Roland wave table is ok for what it is meant for and that is, that people can exchange midi files due to its universal availability. The problem arises when a midi file is played back by using a wave table that is different to the one the midi file was sequenced in.

Best wishes,

Herbert
