Stepper automation 256 max reso , 8bit?

So I did a test .a

First sample

Hard paned left

Macro assigned to stepper reset ( volume ) ,stepper op.set to 256 linear mode , …so the macro scans trough the stepper …automated the macro 1 pattern .( see here or details about stepper max imum resolution )

Second sample …

Hard panned , macro directly assigned to volume input operator . automated macro …

R endered output , inverted phase of right sample , process ----> adjust sample format mono = total phase cancelation

Which means that the automation resolution ( controlling the direct volume input operator ) is also 8 bit resolution . ( 256 values )

Or maybe the resolution of the gain input operator is limited to 255 values

Or am I missing something ?

hmm can’t see the ‘attach file’ option here …
