Automation in itself can not be linked 2 a controller... u either have the possibility or recording knob movements that are assigned 2 functions (like 4 instance cc 74 is the cutt off of A1) or not...
don't forget that if u have a loop a lot of times the writting is erasing yer previous knob movements...
as far as I can remember the best way 2 have the movements quantized is 2 draw' em by hand with the snap in snap to quantise, the quantize points u define in quantize (for instance 1/16)...
Check the previous posts about automation in SX, this is one of it's biggest sell points... I couldn't do with out it for synth tweaks and mixing automation, efx etc...
