Either if it's a single midi track or a full composition* i will use the best sounding samples and soft synths so that your midi will have the best quality and sound possible. Just send me your midi file and i'll send you back the audio track in wav or mp3 format. I can also give you a sample before ordering so you can be sure for what you'll be getting.
*1 gig covers a midi file that's up to 4 instrument tracks. For midi files with more tracks please check the gig extras.
