# Detect long button press
# Red Heron Music, Nov 6, 2022

# Notes
# delays do not work in MDP2 version of SB
# see post on problems with delays below 150 ms in SB on Mac

# Example uses
# Cc 01 on Ch1 is monitored button
# i0 to store button state
# i1 to store delay time
# F0 58 10 - synthetic SysEx message for time tick

If Load
     Ass i0 = 0 # initialize button to off
     Ass i1 = $200 # Default delay time in ms
End

If M0 == B0 01 # Detected button action
     If M2 > 0 # Button is on
          Ass i0 = 1
          Snd F0 58 10 F7 +I +Di1
          # Any non-delayed button on actions here (optional)
     Else # Button is off
          Ass i0 = 0
          # Any button off actions here (optional)
     End
End

If M0 == F0 58 10
     If i0 == 0 # Button now off, no action
          # No Action
     Else # Button still on, take delayed action
          # Example action
          Snd B1 20 20
     End
     Block # Block synthetic message
