I didn't realize the Matrix 6 even had aftertouch until I connected a generic keyboard controller to the midi in and played some things. I couldn't believe the difference, amazing filter control and all sorts of neat things coming out of my Matrix 6 that I never knew were 'supposed' to be happening when I pressed the key down harder.
If anyone has any tips on troubleshooting or repairing the aftertouch on a Matrix 6 I would appreciate it.
Thanks!
