Tom. The after touch works well with Guitars as well. Regarding
having to do the settings for each and every voice that you feel wants it.
You only have to copy the already set voice aftertouch setting to how many
User Programs you want which will copy the effects, then just change the
voice in each of the User Programs and they will respond to the aftertouch
already there..
I have programmed A11 to A18 only, with these aftertouch voices covering
most blown instruments and Guitars which are the only ones I feel I need.
When using a style you can easily lock the USER PROGRAM-STYLE \BUTTON and
then just move through the A11 to A18 to change your real-time voices with
the appropriate aftertouch setting.
On the VA Series a lot of voices are already programmed with after touch
setting.
