Hi, people, there are some mistakes on Craig explanation, i go explain just one now. I have one Mediastation X-76, one SD1, one XP-80 and a Korg X3. I open all my keyboard´s some times to clean. Like "all" people know near the keyboard key´s board (internal) there was a ribbon "connection" with 2 wires to make aftertouch. Right ? It´s the same think that tell the aftetouch is MONO. In audio lexic the aftertouch is allways stereo and one aftertouch per KEY, sow my XP80 have 76 ribbons connector´s of aftertouch, one to each note KEY. wrong don´t have, all people can open a XP-80 and see it with eyes. It´s just one ribbon connector (MONO). XP-80 DON´T HAVE AFTERTOUCH, but soun´d have aftertouch. ( INTERNAL SOFTWARE CONVERT KEY PRESSURE TO MONO AFTERTOUCH ). Key pressure is the right name to give to all keyboard´s, because is natural that key pressure is mono and aftertouch poly. How many keyboard´s that have "aftertouch" have many ribbon connector´s ??? SD1 ?? My not, X3 ?? my Not,,, X76 ?? my not..XP-80 ??... All my keyboard´s and off course your´s have fisical key pressure and "aftertouch" emulation mono. Saw MS X76 don´t have aftertouch, and XP80 not too, SD1 not too and X3 not too. Better, all keyboard´s have the same phisical system, in this ideia SD1 have aftertouch, XP80 aftertouch too, X-76 aftertouch too and X3 aftertouch too. Now it´s true or false the ORIGINAL aftertouch on all keyboard´s ??? off course MS X76 have "aftertouch" too, but tecnical it´s named "Key pressure" like other companies keyboard´s too. I´m completey open to explain better this if you want. Now i´m a little busy, latter i can post more explanation´s about Mediastation X-76 features and send to this forum a demo of me playing. I´m a alive player. Thank´s to all !! Bye
