Topic: Realistic sostenuto pedal behaviour
Out of curiosity I tried the sostenuto pedal while I was playing recently(I usually don't use it). I found the pedal behaves differently in Pianoteq compared to my RD-800(used as the controller for Pianoteq) internal sound, as well as the Ravenscroft 275 from VI lab, that is the override of the damper pedal while using sostenuto.
scenario 1: play and hold keys -> sostenuto down -> release keys -> play with damper. In this scenario, the damper works normally and won't affect the notes held by sost pedal. Pianoteq, Ravenscroft 275 and RD-800 all function the same way.
scenario 2: hold keys while holding the damper -> sost down and release keys -> release damper. In this scenario, both RD-800 and Ravenscroft 275 behave the same: damper works normally and does not affect the notes held by sost pedal, and sost is only holding the pre-pressed keys. In Pianoteq however, the damper is overridden by the sost pedal, which means as long as you are still holding the sost pedal, ALL dampers are up and won't be affected by the damper pedal.
I've never tested this on a real grand piano, so I'm not sure which way resembles the real behaviour of a sost pedal on one. Personally I prefer how the RD-800 and Ravenscroft behave as it allows more control of the sustain and such. Hope Pianoteq could do the same.
Any opinions? Has anyone tried this on a grand? thx!
