Al,
I read your request to Steve Demming and I guess we look at this in a different light.
To me, the Music Finder Directory (MFD) is merely a miniature version of a registration, but conveniently packed into a single, scrollable folder that makes access very quick and easy. Granted, the MFD only has a limited number of features, but it is a very usable feature that many entertainers never seem to utilize. Donny is a good example of this.
Registrations, on the other hand, are an extremely powerful tool. You can pretty much do anything with a registration and save those steps in two formats--a complete bank of 8 for a single song, or one song for each of the 8 slots in each bank. Now, there are advantages and disadvantages to both methods. Eddie (Btweengigs) likes to utilize an entire bank for a single song. In doing this he can quickly look up a song in a manner very similar to using the MFD. The songs are automatically listed alphabetically because the entire bank is named by the song title. You merely press the Registration button, then using the Data Scrolling Wheel scroll do the list to the song you wish to select, press the select button and you're ready to go. You can even do this while playing another song and that song will not come into play until you press the select button.
The same is true with the MFD, but not many folks are willing to take the time to create their own, custom MFD and create registrations as well. Creating a custom MFD can either be done on the keyboard, or by using Michael Bedesem's Music Finder View program, which is downloadble at no charge. It's very easy to use and tailor made for each keyboard model.
If it saved transpose information, DNJ would love it! But, the MFD has never saved this kind of information--that's why they have both the MFD and Registrations. The MFD does save information pertaining to: Intro, Variation, Style, Tempo, Song Title, Genre, beat, allows you to copy to a favorites list and have searchable keywords.
Now, if I recall, you want the MFD selection to link to a registration. To me, that makes no sense at all. You would have to create the MFD, then create an associated registration for the exact, same song. It's double the work for the same, end result.
I guess from my viewpoint, both the MFD and registrations are both powerful tools, but they are different tools/features on the same keyboard. To overcome some of the limitations, particularly the lack of saving transposition, I merely indicate the key that I play and sing the song in the song's title. For example, "Country (C) Roads" in the MFD tells me that I perform this song in the key of "C". "A Fool Such (F) as I" indicates that I do this song in "F". So, if you're one of those guys that plays everything physically using "C" you know where you must transpose to just by looking at the title. In a registration, that transposition information can be saved and transposed automatically when the registration button for that song is depressed.
Hope this helps,
Gary
