Have you tried the other gain eventprocs (CMOSGain, VgaGain, CdsGain, etc)?
Yes. Some of them work, some cause crash.

On EOS M cameras the exposure gain can be controlled using "Capture.SetGainNormalApexWholeSerial" and "Capture.SetGainNormalApexRegularDrive".

I assume that the exposure gain value = SV - 576. (576 is SV for base ISO=200)
Exposure values returned by ShowCurrentExp function can not be used for FRSP, so I use PROPCASE_TV and PROPCASE_SV instead.
