Hello.

The possibility of what you can do to improve the sound is endless, but ultimately it boils down to the tools YOU have to work with if your the one wanting to enhance the sound.

I often get people coming to my Studio wanting to sing covers of songs or just looking for backing tracks. What I do is buy the songs in midi file format, then delete all the GM/GS compatibility from them and remap everything on a KORG OASYS to make the most from that Keyboard.

It's not just a matter of picking better sounds either, the effects play a major roll in the quality. Putting a compressor on the drum track for example makes the drums pack a good punch.

What keyboards have you to work with ?

I do offer the service of taking midi files in and giving them back to the clients as Wave files performed on an KORG OASYS, so if that's something you would like to avail of, it only costs 20 Euro a song.

Regards
James
