I’m wondering if Halion supports half-pedaling sustain. So far it seems to me that it doesn’t.
(For those who don’t know what exactly is a “half-pedaling sustain”, this is a feature that allows the sustain length to be varied depending on how deep the pedal is pressed, so you get a more realistic sustain, like you would get on a real piano. But in order to get this, you must have a sustain pedal (e.g. Roland DP-10) that transmits continuous data like an expression pedal and not just on/off messages like a standard sustain pedal; and also you need a keyboard (e.g. Roland Fantom) or a software instruments (e.g. Pianoteq) that knows how to interpret that data and vary the sustain length accordingly.)
