I am trying to load some wav files onto my SD Card through the Data Editor software, and have been unsuccessful. Although, I have my wav files in the correct location to be transferred from the left pane to the right pane, nothing happens. The files were made available in the left pane by clicking the Preferences tab, and then the Audio tab-the recommended method on this forum. I click & the drag the item and am unable to drop it in the right pane. Nothing happens. Some of the files are complete songs of various tempos, and some are samples. The files are 16bit 441khz files that were created using FL Studio. The latest firmware has been installed on the XW-P1, and the I am running the latest version of Data Editor on my laptop and desktop. I've even tried with the P1 connected via USB, still nothing. Also, I put the SD Card in the P1 just to see if the files had been been transferred over, and there were no files available. Any help would be greatly appreciated. Also, unrelated; my P1 was in storage for about six months, and was left standing upright. Today when I pushed the Play button, no sound was heard. The keyboard played notes, but the play button would not work in perform, tone, or step seq. mode. I did a Factory Reset, and Voila. The Play button works again. Hope that helps someone. Thank you. B
