@andyhornblower Thanks for your suggestion.
The issue with that, is that we designed the physical model to play well in a certain range. And while we could feasibly extend it a few semitones lower, it becomes a slippery slope, as we need to rework the physical model to include lower tones, which then prompts people to ask why we can't go even lower, etc.
I hope this makes sense, we will consider your request as much as we are able but can't promise anything to that end. Let me know if you have any further questions.
