Yamaha CS80

Do you think this is there so you could overwrite a slow attack with
aftertouch prior to the decay sequence and is this vector based as in
+Change of CV is touch responsive and -Change of CV is touch
irresponsive.......

BTW....My girlfriend is exactly like this....When I touch her, her
response is to peak at a high amplitude before I get cutoff and then she
is in touch irrisponsive mode...with sharp punchy control....releasing
me to hang with the transients.... thats why I still hang on to the ol
eighty.....lol
