Regards

• Server tps may affect play speed.
• Midi files that are too fast may have some notes lost, the smallest time unit is a minecraft tick(50ms), notes closer than this may be considered as notes at the same moment.
• The velocity,pressure or volume of a single key would not be considered as there's no way to present this in minecraft.
• Only midi speed change message and key on messages would take effect.
• generating structure may cause performance issues. There's no undo, so be careful!
• structure width must larger than 16, you can calculate a approxmate value by lengthInTicks*3(cell width)/250(height).
