okay let me explain a bit, based on my own knowledge
lets say you have a three-note chord and the polyphony/voices parameter is 2
when the synth recieves that chord, it will strip away less important voices based on it's settings, meaning that the three-note triad gets reduced to a two-note diad
this is useful because some sounds don't work well when they're played on top of each other more than once or twice, the waveforms all collide and sound noisy because they're being played at different pitches at the exact same time (i don't 100% know what i'm talking about so take everything i say with a grain of salt, though)
so simply i'm asking if i can strip away notes (decrease the amount of voices), with my soundfont
