Playback for extreme registers/General MIDI compatability

The General MIDI convention specifies 128 pitch values from C-1(C-2) at 0 to G9(G8) at 127, with Middle C at 60. However, notes lower than C0(C-1) and higher than C8(C7) simply do not play back at all when inputted into the score. This may seem a minor issue as most instruments come nowhere near these limits, but it is a huge problem for comparability with MIDI files, and can be quite limiting when it comes to transcribing electronic music. Is there anyway something can be done about enabling support for playback of these notes, at the very least for the MS Basic soundfonts?
