Okay fair enough Fran, TBH I thought it was clear enough, but to explain a bit more simply:

I am not talking about selecting MIDIS per se, I am talking about a special midi file created to load a Songbook Entry - be it a style, an MP3 or a song based midi file - these are a one bar "oneshot" midi that uses NRPN CC's plus the Data Entry CC, which when transmitted over a nominated "control" channle on the PA series, then automatically loads the Songbook entry with all resources - Microphone EQ and Harmoniser settings as well.

Look why don't you check this You Tube clip - which I think explains it even better ....

Having a data base of 9,999 songs to choose from makes doing requests a snap!
It also means that ....let's say I have prepared a playlist at home for the 3rd set of the night - I have my 20-25 songs all ready to go - BUT then I am playing at the gig and I find what I had prepared is not working, with the instant nature of the KSB and the fact there are son many entries instantly available I can simply change to dynamically (you do understand what I mean by dynamically? Not being rude, just asking....) selecting songs, then if I find the audience is getting more responsive, I can slip straight back to the prepared playlist...

You know as well as I do it is harder to get folks ON the dance floor than to keep them there

I know the Roland is easy to use but the number restriction (128) was always an issue...Why Roland could not have extended the function past a basic single bank MIDI set is beyond me!!! And I will also say that had Roland HAD the access to more entries (without the need to keep loading a whole UPS to get one or two songs) I daresay I would not have gone back over to Korg with the PA2xPro..

Does that help?
