my singing monsters zynth farm help

anyone know how youre supposed to make zynth farm progress in my singing monsters go somewhat faster? i dont wanna have to spend like 12 hours waiting just to get 1 zynth woken up when i could be making actual progress on my other islands. 106 zynths times 12 hours is 1272 (its probably even more i had to count manually) i dont wanna spend 1272 hours on one farm help
