I was trying to find a program that let you play MIDIs using soundfonts other than Microsoft GS/GM but wouldn't completely butcher the pitch-bending/LFO like FL Studio does.
Someone on Soundcloud told me that the program they used to play/record Fiery Cavern (Wario Land 4 tune) in its original form, and with such quality on top of that, was called SynthFont. I've since downloaded it, and.
It's very useful for testing out soundfonts and making MIDI arrangements in a short amount of time.
