I had a soundfont open, changed the buffer size to 16, then played a note and went to change it back to 1024. Upon changing and hitting Close the program crashed. It now crashes any time I try to change it back to 1024 regardless of if a soundfont is loaded.
Windows 7 x64 SP1
And on an unrelated note, my MIDI keyboard's notes and such aren't registering on Polyphone. I seem to remember it all working properly at some point, probably on 1.7. Anyway, care to help me out on that front too?
For the buffer size issue you can try to remove to configurations stored in the registry. Launch regedit.exe and remove this node: HKEY_CURRENT_USER > SOFTWARE > Polyphone
Several components within the software have been updated with the version 1.6 of Polyphone. Maybe from that time something has been broken? I would need more details but not sure I can help. It may depend also on midi drivers.
