only just got around to give ACTfix a try and it does not work for me.
my current (working but not extendable) ACT mapping file throws the immediate warning "current ACT mapping is probably severe corrupted, please restore from backup or delete ..."
when I remove the ACT files for a test and start with an empty ACT file I can normally map the ProChannel EQ on the VS-700C ... and also the ProChannel Compressor. Yet the new much smaller ACT file also throws the identical warning and does not allow me to do anything further.
