Advancing step dial

Is it possible to advance the step dial widget by a single step by detecting any change to a CC value? That is, if I change a knob on my controller by any amount, can it trigger the stepped dial forward by one?

    Setting Loopy's capabilities aside for a minute, how would you determine when to trigger the movement? If you move a continuous controller from 0 to 10, there are 10 changes in that one movement. You'd have to have some kind of timeout to tell the dial only to move once.

    The answer is “yes” in the sense that “on” is a cc value greater than 0, but as @wim mentions turning a knob on your controller is going to send a bunch of values. So you have to think about what you want to happen when your controller sends a bunch of values in succession.

    Right, I was thinking about conditionals. I seem to recall Michael saying that he was working on them but don’t see any evidence that an “if” statement is possible in current version.

    I suppose I could write a Mozaic script that detects one CC value change then goes quiet for a set number of seconds and then starts listening again.

    You don't need to resort to using a timer. You can just set a variable to SystemTime, then check SystemTime minus the variable.

    Something like this (not actually tested):

    @OnLoad
  timeout = 250
  last_change = 0
  channel = 0
  cc = 20
  triggerChannel = 15
  trigger_cc = 20
  trigger_value = 127
@End

@OnMidiCC
  if MIDIChannel = channel and MIDIByte2 = cc
    if SystemTime - lastChange > timeout
      lastChange = SystemTime
      SendMIDICC trigger_channel,trigger_cc,trigger_value
    endif
  endif
@End

    You could handle the timeout in loopy itself if you want. You could have your midi binding in a profile by itself. Have a button in your project called time out. It would have two actions, disable the profile with the binding. Then an action that re-enables the profile. Set the timing for the second action to after last with a delay of how many milliseconds or seconds you want to use.

    @wim and @espiegel123 both are creative solutions! Thx
