Patches and discussion for Ensoniq VFX family

if there was a problem with the keyboard yopu would have a calibration error

as seeing you are not then all is working well

i think its just the os 2.23 thats the problem

the os tells the scanner logic chip what to do and obviously its doing its job right as there is no error flag for the calibration

i think its sensitivety is set to high as its a measure of magnetic force on these coil boards there no actual contact which is good as there is nothing to where out

so when you press harder the magnetic force is stronger becuase the metal plate is closer to the coils

its this magnetic force that the scanner cpu measures for each key

so thats 21 potential poly at signals at 1 time

I just dismounted the keys module, but I do not know how to dismount the single keys.
Do I need to dismount the single keys to check the pcb ?

thanks

Hi Rick!

I have the OS3.0 and KPC 2.33 also. Aftertouch is working, but the "usual" hard touch needed, evdn set at most sensitive.
Have You removed the keys and checked the PCB coils underneath the keys? My VFX-SD once (~18 years ago) had a coil with a broken lane, which made the aftertouch unresponsive, or erratic at best. Floatet on a very thin layer of solder, and have worked since.

The component You see is normal and should of course not be removed ;)
