I’ve tried to use Polyphone 2.2 to subset a soundfont and found the usability on my laptop (Thinkpad 12″, 1024x768) abysmal.
I had to resize the Polyphone window to three to four times the screen width to be able to increase the size of the left pane to even come close to read the preset names (the left pane is not very resizable, and all I get is “♫ 000…ano” for the first preset in the MuseScore_General soundfont “000:000 Grand Piano”.
Of course, sizing the window that big makes it really unusable. Keeping it at 1024px width would be more welcome.
