Known issues with E-Roll Player Software In some cases, the installer does not create the folder for the collection and playlist files. When this happens, an error is reported and lists can not be saved. To correct this situation, click on file on the editor toolbar and select preferences. The location that is referenced in the “default path” must exist. You can either create the folder that is listed or browse to a folder that will be used for the files. It is possible that power management setting will slow down the MIDI tempo. This has only be found to be the case on one computer. It must be some odd mismatch between versions of Direct X and the computer bios or some other strangeness. The latest version of the program has the ability to scale the MIDI tempo to correct this and other tempo problems which effect all files. From the player window, chose setting and them tempo correction and enter a scale factor. This problem has only be demonstrated with power saving options other than “always on” and “Home/Office Desktop” so another solution is to choose one of these settings.
