#2618057 - Today at 12:11 AM Yamaha FC3A half damper midi range

I am wondering if someone could do me a huge favour and confirm the actual Midi output range of the Yamaha FC3A Half Damper pedal within Midi Monitor or any other software that lets you see midi signals. I have one and it behaves in the following fashion: it goes from 0-80 in a very smooth fashion. Once I reach the last quarter of the pedal range, it jumps from 80 to 127, i.e. full sustain. I assume that this is an accurate simulation how half-dampers work on an actual piano, but just wanted to confirm that this is normal behaviour and that it is not possible to reach midi values from 81-126. Btw, I am using it with Yamaha P45 piano.

An actual piano doesn't send MIDI events. wink However, when we push the damper pedal, a first segment doesn't do anything, a second one dampers more or less the strings, and when the dampers don't touch the strings, we can push the damper pedal even further : this will not have an effect.

You will find the 3 phases on the following curve : a flat curve when the dampers don't move, an increasing curve when the dampers quit the strings, and another flat curve when the dampers don't touch the strings.

Note: the FC3A is just a potentiometer : it just send a continuous range of resistance. I think the behaviour of the continuous range 0-80 and the step 80-127 comes from the P45. Different pianos will have a different behaviour (my Yamaha just sends 7 discrete values).

Thank you Frédéric! I assume that is the case since otherwise I would have to push the pedal all the way to get the 127 value. What is your Yamaha piano? Out of curiosity, could you tell me what the 7 discrete values are, and how hard do you have to push the pedal to get to the full sustain (127) value? Mine registers 127 about 3/4 of the way in and then the last quarter of the pedal travel it stays constant at 127.
