Re: [oberheim] Matrix 6 Aftertouch
Looks like the pressure sensor connects to U17, which is probably a 556.
with an ohmmeter you should be able to unplug it from the processor board
and measure the resistance as you press down on a key. I think the pressure sensors
fail after a while on lots of keyboards from this era. Shouldn't be too hard to
replace. You can adjust the resistor values around U17 if nec to get the desired action.

[oberheim] Matrix 6 Aftertouch
I have a Matrix 6 and just realized my aftertouch is not working. I haven't opened this up to delve in to it just yet, I am wondering if anyone else has run in to this issue and had any luck repairing it
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.
