I've tried and tested the installation procedure on Windows 6.2 and 7 with no ill effects. There are instructions included with it to help you with the installation for Windows 7 specifically, but in all cases you can remove the U-220 batteries, re-insert them at a later date, and you'll be fine.
Here's what else you could do with a Roland U-220. It is faster to get the patches to the U-220 with a patch library program such as SoundFont Librarian than it is to program each patch using the very Roland default patch editor.
Another issue that I have seen with the Roland U-220 is that the patch librarian will sometimes read in the wrong patch data. To test this, you'll have to set the MIDI playback to looping and adjust the initial recieve value on the meter. Then, play the patch. You should see the meter dip while the patch is being played. If that is the case, then the patch librarian is reading in the wrong setting for the patch. This can be fixed by removing the patch or going into the main SETUP.EXE and adjusting the MIDI connect to the U-220. There is apparently a value somewhere in the MIDI connect settings that can be set to \"Looping\" or \"Fixed\" for the U-220.
Below there is a utility called \"Recurse.bat\" that when run recursively will scan your system looking for all U-220 patch folders and scan recursively for patches in those folders. This can go through quite a few folders (mostly banks of for unthemed RB's and RB2's as well as banks of banks of RB3(4) banks of RB3(4) etc. This tool is a possible add-on for the standard MIDI Piano Roll Browser. Importantly, it does not play the sample files back in the folder being scanned, unlike previous tools. It is best used when run on a Windows system without demultiplexing. You'll need to enter your U-220 system folder for the program to run. Note that Roland does not have any sample files for the U-220 in an unencrypted format, so this tool is necessary if you want to use those files. The program does not attempt to censor the external media, ESD or other such problems that may be present, so the only impact this program has is in potentially larger memory footprint. If you (the user) would like Roland to package the sample libraries to perform this scanning function, a request can be sent to them. Both Windows XP and Vista are supported, and it only needs to be run if your system has a directory that has a U-220 patch folder in it. I've tested this on both. This utility replaces Roland's standard patch scanner that would scan from a standard factory directory that had Roland patches in it, i.e. one that was made by Roland and not the user. The standard scanner searches for media inside the media directory, if found, to make its patches, and can scan all per-bank directories as well as per-bank media directories. d2c66b5586
