Shared piano seems to not enjoy playing back generated saves and consequently only allows 0.25% playback speed or 3.00% playback speed... neither of which are very enjoyable to use.
Are you saying Shared Piano won't let you play it at normal (1x) speed? If so, could you please send the link to the MIDI file you used and the saved Shared Piano link?
