Okay, load your sequenced song and press the play button to turn it off. Press the program menus button>sequencer>record & edit>step record>press #6 (ctl) and the tempo will show at the upper right and middle lower screen. Change the setting with the tempo wheel to whatever tempo you want and you'll see the value change>press "yes">exit the screen>press #7 (rhy) and repeat the process to change the tempo value>yes>exit the screen>exit sequencer. The screen will show your song with the new tempo in place. Go to program menus>control>panel memory mode and check to see if you are in expand or normal mode.>exit menus. In panel memory section press set and the panel memories you use for your song. If you recorded in expand mode, you will have to set the new value in each panel memory you used. Turn the tempo wheel in each pm position and press set and the pm button. If you used normal mode for recording, you should only have to do this once. In any case, press each pm position you use to double check that the new tempo value is showing, and if not, change it and press set/pm button once again. When all this is done, press the sequencer play button to bring up the screen with the new tempo and reset the sequencer. Save the song to a blank spot on a disk and reload when the process has finished. Your song should load with the new value. Play it through once to make sure that all the changes happen as you programmed them and the tempo stays at the new value. Even though you may do this a dozen times with no problems, things happen, so always double check before you copy the song file back to the original disk. Personally, I like to use expand mode for changes and move through the panel memory positions with my foot switch. It's prone to stubbornness at times, but makes for smooth changes. This should clear up your problem.
