AFTER TOUCH work-around for Garritan users:
--After getting my Aftertouch turned on in the Global preferences, I found that the keyboard just doesn't handle Aftertouch very well, as per the posts on this thread.
--I changed the response curve to key pressure -- there are only a few choices, and even at the most sensitive, getting Aftertouch is totally hit-and-miss. There's no way someone's playing style could adapt successfully to something that works sometimes, often doesn't, requires shifting your hand position around etc.
--Conclusion - Really bad implementation of Aftertouch on the A-800 Pro, basically unusable.
SOLUTION - Which is for Garritan users:
My main libraries are from the Garritan line, and many of the instruments use Aftertouch for vibrato. For years I've just drawn it in via the PRV. One of the big attractions for me with the Apro was to finally have a keyboard with Aftertouch. After seeing that part of the keyboard is a big failure, I Had to come up with a work-around.
I made a new Control Map. Using #19, "Sonar2" as a template, I reprogrammed the Mod Stick to send out Aftertouch instead of CC1. I reprogrammed knob R9 to send out CC17 which controls the speed of Aftertouch Vibrato in Garritan.
My new volume pedal is for controlling Garritan volume via CC11. That controller is interchangeable with CC1 for volume in Garritan.
I copied that edited map into slot #1 which is pre-set for Cubase. Now Map 0 is the basic Sonar map, and I change to map 1 for when I'm recording with Garritan.
Works great. Finally--beautiful, full range Aftertouch which is perfectly responsive.
Losing knob R9's default, panning of the Master bus, is no loss since it's very rare that the Master's pans need to be changed.
If I'm working with a synth which needs standard CC1 for vibrato, then I stick with Map 0.
Works great.
