I created an organ soundfont with 11 instruments. Now I want to create a preset called TUTTI with all the instruments included. The idea is to turn the instruments on/off with a MIDI controller or something else. This would be a dynamic preset. So that I can (de)activate the instrument with on klick to get combinations while playing the preset. But for now I have no idea how to do this in Polyphone. Is it possible? Perhaps you can help me with this.
