An outstanding bug report I just received from the git interface (by mail), sf2 inputs lacked the punch inputs since the addition of input combinations 1 year and a half ago ! it was just 2 characters to change to fix it, but it's quite outstanding !
I am currently lazy so it's fixed on git and those who compile their own binary can use the fix, but is it really useful to make a new binary for this now ? (1 year and a half before someone noticed it, I guess it can wait some more !).
Anjyway reply to this thread to complain if you really want a new binary !
