Mirza, I have edited more than a dozen sounds using the onboard programs and never had a problem - they all came out great and have been downloaded thousands of times. There is nothing poor about the sound editing and style editing programs on Yamaha arranger keyboards, but only if someone takes the time to read the damned user manual. If you don't read the manual, then it's a user problem - not a keyboard program problem.

Have you ever edited any of the voices or styles on your T5? If so, how about posting them so we can all benefit from your expertise. I have posted my entire USB drive with thousands upon thousands of edited styles and many, many edited voices.

Good luck,

Gary
