I think there is an issue with the aftetouch on a single key. It is fully modulated every time I stike it. Is there any way to disable the after touch in the keyboard settings? Also how could I fix this?
** note I’m still having an issue with the digital noise in my earlier post. I thought it could be the after touch, but I used my DX7 as a controller to the SQ80 and still had the same noise problem. The modulation Problem was resolved by using the DX7 as a controller, but I would like to fix the SQ80 ha
Some steps I would try would be to swap that key with the same note from another octave to see if it could be the key itself. A keyboard connector issue is another possibility. I see in the schematics that the pressure circuitry for each key consists of a resistor, transistor, and coil. An open or shorted transistor sounds like a likely candidate. I believe some of that circuit is on the “poly pressure keyboard” circuit board.
Sam, thank you! It’s an after touch problem. Disabled per your direction and it fixed it. As cool as it is, I never press the keys hard enough to use it, so I’ll keep it disabled. Thanks!!
