iOS, damper seems to be stuck open
Just downloaded the iOS version. Possibly, I don't know what to expect but even on Basic Piano it sounds as though the damper pedal is stuck open. Operating the Deamper pedal has not effect, but sustaining notes are cleared when Sostenuto is raised.
iPad 2018, iOS 11, using Roland FP-80 as controller with Roland pedals
The pedals work normally with the piano, and also with other apps.
MIDIScope shows Damper xmitting as CC 64, Sostenuto as 66. The action of the app is not affected by selection of continuous or switch operation on the Roland pedals
Appreciate your work. I hope this is helpful
