hi, I wanted to change the volume of 2 pipes (Organ setting/per pipe tuning): Pedal: Oktavbass 8' of the Silbermann Arlesheim Organ by Organ Art. It works, but the settings cannot be saved. I move the slides an then press "Close". Yet an earlier setting in the same rank is still saved. The saving is lost after every new start of the system. Can you help me? Sincerely, Wolfgang
