Not sure why you would want to do this but......
I can think of three of ways of doing that Rog :
1. Probably the easiest way.... Since any Intro will play in the key of the Chord which you initially 'play' in your Left Hand, or a Single note below the Split Point, with Synchro/Break, Start/Stop and Intro 1 or 2 selected, you can start the Intro in any key you wish. Once the Intro part of the style has finished, then just play a Chord below the Split Point in the desired key for the rest of the song. For example : if you wish to have the Intro in Bb, but the main song in C, set the KN7000 to say Intro 1, Synchro/Break On and Start/Stop On. Either play a Bb chord or just a Bb note below the Split point and the Intro will start in the key of Bb. Watch for the Last beat of the Last measure of the Intro and then immediately play a C chord below the Split point and continue to play as normal in the key of C. This will work with any combination of two keys.
2. Once you've decide the new key for the intro, set the new key before you start playing, using the Transpose Function, and just before the actual style part starts to play, hit both Transpose buttons to cancel the transpose function. Will probably take a bit of practise to get it just right and of course will depend on whether it's a 2, 3, or 4 measure Intro. Try watching the Red LEDs (Beat counter above the Start/Stop button) and as soon as the fourth led turns on, on the Last measure of the Intro, hit both Transpose buttons. This assumes that the actual Style will then be playing in your desired key, when the Transpose function is cancelled (i.e. no key shift)
3. If you wish to have your actual Style play in a key which already uses the Transpose Function, then method 2 of course will not be suitable... However, you can achieve this using the Panel Memory....
Select the desired key for the Intro and store this in Panel Memory 1. Select the desired key for the actual Style and then store this in Panel Memory 2.
As before, start the Intro (with Panel Memory 1 selected) and when the Intro has reached the last beat of the last measure of the Intro, hit Panel Memory 2.
If you are already using Panel Memories to store Set-ups for the song, then just ensure that these set-ups are selected in the Panel Memories 1 and 2, select the appropriate key shift for Panel Memories 1 and 2 and then save back to the Panel Memories.
If you are using a Sequence, rather than just playing 'Live', then these Transpose Functions can be incorporated into the Control Track of the Sequence, and will then be executed automatically, as the Sequence plays back.
Hope this helps Rog.....
