Just an idea - hands might be charged by static electricity. Could it influence the encoder function?
This could easily be fixed with rubberbands or shrinkhose at the encoders. ESD wristband would work too.
No seriously Id go with KaiS idea:
"RME fixed it with a very sophisticated filtering in the latest firmwares.
Default setting usually fixes it.
"If not, increase the filter value under:
SETUP / Options / Display / Encoder Filter /"
This from MC´s firmware entry:
"Encoder jumping and direction errors: This firmware includes a new logic unit that intelligently detects and eliminates encoder switching contact errors. In addition, there is a variable filter with levels 1 to 5. Default is 1, which is largely similar in feel to the previously used filter. Higher values lead to an attenuation of very fast changes. Strongly jumping or backward running encoders can in most cases be used normally again with the setting 3. Very fast, short rotations can be replaced by medium-fast rotations after a short period of familiarization."
Id go with this before rushing to holographic room treatment.
Have a nice weekend.! Time to pop a can and put some cans on..
